Echoviruses 22 and 23 are classifed as human parechovirus antibiotic cream for dogs buy tetracycline with a mastercard, which cause febrile illness, exanthema, sepsis-like syndromes, and respiratory and intestinal tract infections. The epidemiology and treatment sections have been updated; recom mendations for immunization of adults with diabetes mellitus and a fgure showing stages of acute hepatitis B virus infection and recovery has been added. For diagnosis of neonatal herpes, swab specimens from mouth, nasopharynx, conjunctivae and anus can be obtained with a single swab ending with the anus and placed in one viral transport media tube. Recommendations have been updated to include new vaccines, an algo rithm recommending an approach to immunization of children with egg allergy has been added, and the current status of antiviral recommendations has been updated. Quadrivalent infuenza vaccine(s) are expected to be available for the 2013–2014 infuenza season. The outbreak of measles in the United States in 2011 is highlighted, as is the need to immunize infants 6 through 11 months of age who travel internationally. Recommendations for routine use of meningo coccal vaccines for adolescents, and for children and adolescents at high risk of disease have been updated and placed into 2 tables. Specifc changes include guid ance for adolescents and people in high-risk groups, need for booster doses, and vaccine interchangeability. Diagnostic and antimicrobial prophylaxis after exposure have been updated, as have recommendations for Tdap use in children 7 through 10 years of age, pregnant women, and adults of all ages. Mebendazole no longer is available to treat pinworm and other parasitic infections, including giardiasis, ascariasis, trichuriasis, and hookworm infection. There are now 9 human polyomavi ruses associated with a variety of diseases, generally in immunocompromised people. The postexposure prophylaxis regimen of rabies vaccine has been reduced from 5 to 4 doses given at 0, 3, 7, and 14 days following exposure. The epidemiology of rotavirus disease showing the marked reduction in hospitaliza tion following licensure of rotavirus vaccine has been updated. Changes to management of newborn infants include use of lumbar puncture in infants who have signs of sepsis, change in use of intrapartum prophylaxis and inclusion of a revised algorithm for management of newborn infants with possible risk of early-onset group B streptococcal disease. Isoniazid and rifapentine, a long-acting rifamycin, have been added, but because evaluation in children younger than 13 years of age has been limited, this therapeutic option is not recommended for this age group. The benefts of therapy with doxycycline for serious infections, including those caused by Rickettsia, Ehrlichia, and Anaplasma organisms, has been clarifed. The Antimicrobial Stewardship section highlights appropriate use of antimi crobial agents in children with the aim of decreasing inappropriate use that leads to resistance and toxicity. The Drugs for Parasitic Infections section is reproduced with permission from the 2010 edition of the Medical Letter. A new table titled Principal Adverse Effects of Antiparasitic Drugs has been added, and the table titled Principal Adverse Effects of Antiparasitic Drugs in Pregnancy has been updated. Haemophilus infuenzae and Bacillus anthracis have been added to the Exposed Host column, and rheumatic fever has been added to the Vulnerable Host (Pathogen) column. The National Childhood Vaccine Injury Act Reporting and Compensation Table has been restructured to include adverse events and intervals from vaccination to onset of event for reporting and for compensation. The table of Nationally Notifable Infectious Diseases in the United States has been updated to include diseases notifable in 2012. To accomplish these goals, physicians must make timely immunization, including active and passive immunoprophy laxis, a high priority in the care of infants, children, adolescents, and adults. The global eradication of smallpox in 1977, elimination of poliomyelitis disease from the Americas in 1991, elimination of ongoing measles transmission in the United States in 2000 and in the Americas in 2002, and elimination of rubella and congenital rubella syndrome from the United States in 2004 serve as models for fulflling the promise of disease control through immunization. These accomplishments were achieved by combining a com prehensive immunization program providing consistent, high levels of vaccine coverage with intensive surveillance and effective public health disease control measures. Future success in the worldwide elimination of polio, measles, rubella, and hepatitis B is possible through implementation of similar prevention strategies. High immunization rates, in general, have reduced dramatically the incidence of all vaccine-preventable diseases (see Tables 1. Yet, because organisms that cause vaccine-preventable diseases persist in the United States and elsewhere around the world, continued immunization efforts must be maintained and strengthened. Discoveries in immunology, molecular biology, and medical genetics have resulted in burgeoning vaccine research. Licensing of new, improved, and safer vaccines; anticipated arrival of additional combination vaccines; establishment of an adolescent immunization platform; and application of novel vaccine-delivery systems promise a new era of preventive medicine. The advent of population-based postlicensure studies of new vaccines facilitates detection of rare adverse events temporally associated with immunization that were undetected during prelicensure clinical trials. Identifcation of the rare occurrence of intussusception after administration of the frst licensed oral rhesus rotavirus vaccine confrmed the value of such surveillance systems. Physicians must regularly update their knowledge about specifc vaccines, including information about their recommended use, safety, and effectiveness. Each edition of the Red Book provides recommendations for immunization of infants, children, and adolescents. Whereas immuni zation recommendations represent the best approach to disease prevention on a population basis, in rare circumstances, individual considerations may warrant a different approach.

Sources of Vaccine Information In addition to the Red Book, which is published every 3 years, physicians should use evidence-based literature and other sources for data to answer specifc vaccine questions encountered in practice. Each product insert lists contents of the vaccine, including preservatives, stabilizers, antimicrobial agents, adjuvants, and suspending fuids. Health care professionals should be familiar with the label for each product they administer. Most manufacturers maintain Web sites with current information concerning new vaccine releases and changes in labeling. Additionally, 24-hour contact telephone numbers for medical questions are available in the Physicians’ Desk Reference ( The monograph also provides information about other vaccines recommended for travel in specifc areas and other information for travelers. For additional sources of information on international travel, see International Travel (p 103). Annual course offerings include the Immunization Update, Vaccines for International Travel, Infuenza, and a 9-module introductory course on the Epidemiology and Prevention of Vaccine-Preventable Diseases. The course schedule, slide sets, and written materials can be accessed online ( This system responds to immunization-related questions submitted from health care profession als and members of the public. The hotline is a telephone-based resource available to answer immunization-related questions from health care professionals and members of the public. Appendix I (p 883) provides a list of reliable immunization information resources, including facts concern ing vaccine effcacy, clinical applications, schedules, and unbiased information about safety. Two resources comprehensively address concerns of practicing physicians: the National Network for Immunization Information ( Information can be obtained from state and local health depart ments about current epidemiology of diseases; immunization recommendations; legal requirements; public health policies; and nursery school, child care, and school health concerns or requirements. Information regarding global health matters can be obtained from the World Health Organization ( Online catch-up immunization schedulers are available for use by parents, other care providers, and health care professionals. The schedulers are based on the recommended immunization schedules for children, adolescents, and adults. The schedulers, which can be downloaded, allow the user to determine vaccines needed by age and are useful for viewing missed or skipped vaccines quickly accord ing to the recommended childhood and adult immunization schedules. The inter active vaccine schedules are available at the following sites: ♦♦ catch-up scheduler. Questions should be encouraged, and adequate time should be allowed so that information is understood ( This applies in all settings, including clinics, offces, hospitals (eg, for the birth dose of hepatitis B vaccine), and pharmacies.

The size of the molecule membrane and cell wall, perhaps becoming crosslinked to the lat varies greatly according to source and method of measurement, with average M values of 2. Glycogen serves as a cellular store of glucose; it occurs, fre the soya bean, Glycine max. Structurally, it resembles arachin, edes quently as granules, in all animal tissues, especially liver and skel etal muscle, and also in some bacteria and yeasts.

The anions of similar glycine conjugates of other bile liver, and erythrocytes, the glycogen having abnormally short outer acids are known. Sodium glyco glycogen disease (or amylopectinosis or Andersen’s disease) is a rare cholate is the chief bile salt in humans and herbivorous animals. It is condition of infants in which there is a generalized deficiency of 1,4 useful as a detergent; aggregation number 2. It is characterized by he patic cirrhosis, hepatosplenomegaly, ascites, and glycogen with ab normally long outer branches; the glycogen may not accumulate H3C O excessively. There is no hypoglycemia but muscular exercise H H fails to elevate the blood lactate concentration. Glycogenin catalyses formation of phate carboxylase when this is acting as an oxidase. It is converted to a glycosidic link between a glucose and one of its own tyrosines glyoxylate by glycolate oxidase (see 2-hydroxy-acid oxidase). It is now included with 2-hy forms a primer, which is then extended with further glucose mol droxy-acid oxidase. Glycogen synthase is only catalytically glycolic acid or (formerly) glycollic acid hydroxyacetic acid; hy efficient when it is bound to glycogenin. Hence, the glycogenin–synthase in to a mono or diacylglycerol, to a long-chain base such as sphingo teraction limits the size of glycogen granules. Glycogenin is a sine, or to a ceramide) or (in a bacterial glycolipid) joined in ester monomeric glycoprotein (via its reactivity), tightly bound to the 86 linkage to one or more fatty-acid molecules. By extension, the term is also used enzyme that phosphorylates a specific serine residue in each of the of similar processes in other organisms yielding, sometimes, other subunits of the dimeric phosphorylase b. The mammalian glycerate, 2-phosphoglycerate, phosphoenolpyruvate, and pyru enzyme requires glucosylated glycogenin as a primer (product of vate.

This approach allows for the anatomic assessment of the lower leg get antibiotics for sinus infection purchase 250mg tetracycline with mastercard, foot, and toes. Where possible we also attempt to obtain the axial views at the cervical, thoracic, and lumbosacral regions of the spine (Fig. Interruption of the spine, such as in sacral agenesis, is recognized in the midsagittal view, by the short size of the body of the fetus in comparison with the size of the head. Major spinal defects, such as body stalk anomaly, are easily recognized in early gestation. More subtle defects like hemivertebrae, spina bifida, or early sacrococcygeal teratoma are often difficult to detect when isolated. While open spina bifida can be suspected if the posterior brain structures appears abnormal and confirmed by the targeted visualization of the spine with high-resolution transvaginal ultrasound, isolated closed spina bifida often escape early detection. Three-Dimensional Ultrasound We encourage the use of 3D ultrasound in surface mode for the display of all four extremities in one view (Fig. Note the beginning of ossification of vertebral bodies and the intact skin covering the back. In fetus A, the 3D is obtained from the lateral aspect and demonstrates both upper and lower extremities. In fetus B, the 3D ultrasound is obtained from the posterior aspect of the fetus and shows an intact back. We encourage the use of 3D ultrasound in the first trimester, which allows for the demonstration of both arms and legs (A) and back (B). Follow-up ultrasound examinations closer to term should be considered for leiomyomas in the lower uterine segment in order to assess for obstruction of the birth canal. The adnexal regions should be evaluated for the presence of any abnormal ovarian masses. Often the corpus luteum can still be seen and enlarged multicystic ovaries can be demonstrated in pregnancies of assisted reproduction. Evaluation of the adnexa is commonly performed by the transabdominal approach as the ovaries in the late first trimester are lifted toward the upper pelvis by the enlarging uterus. The presence of any suspected adnexal masses should be evaluated by transvaginal ultrasound if feasible as this allows for more detailed assessment. Common adnexal masses in pregnancy include hemorrhagic cysts, endometriomas, dermoid cysts, and pedunculated leiomyomas (Fig. It is important to note that endometriomas can be decidualized in pregnancy and this appearance may mimic a cancerous tumor (Fig. Follow-up ultrasound examination into the second and third trimesters of pregnancy can help differentiate a decidualized leiomyoma from a malignant tumor. In patients with Mullerian uterine anomalies, such as bicornuate or septate uterus, the localization of the pregnancy and the placenta is easier to demonstrate in the first trimester ultrasound. The leiomyoma was too large to be visualized in one image and panorama view was used. Hemorrhagic cyst (A) is shown with characteristic reticular pattern and fluid level, endometrioma (B) is shown with unilocular ground-glass appearance, cystic teratoma (C) with echogenic foci from the fat emulsion, and a pedunculated leiomyoma (D) with solid appearance and minimal vascularity on color Doppler. Color Doppler shows no vascular signals within the hemorrhagic cyst and endometrioma. Decidualized endometriomas can be mistaken for a malignant tumor with papillary projections. Pregnancy Risk Assessment Findings from the first trimester ultrasound are currently used in some settings to provide for pregnancy risk assessment in order to predict pregnancy complications such as preeclampsia, fetal growth restriction, and preterm delivery. In general, algorithms combining maternal history, biochemical markers, and first trimester ultrasound parameters are used to generate individualized pregnancy risk assessment, which allows for the identification of high-risk pregnancies and for optimization of pregnancy care. This first trimester risk assessment is incorporated into the concept of 26,27 “turning the pyramid of pregnancy care,” which stratifies pregnancy risk from early gestation and coordinates prenatal care according to risk. A main component of the first trimester risk assessment includes Doppler of the uterine arteries. The uterine arteries are easily identified in the first trimester on a parasagittal plane of the uterus in color Doppler. The uterine arteries are typically seen to cross over the hypogastric vessels (Figs. The application of uterine artery pulsed Doppler is considered safe in the first 28,29 trimester, as the Doppler sample volume is applied outside of the gestational sac. Details on the use of uterine artery pulsed Doppler along with other first trimester markers for pregnancy risk assessment are beyond the scope of this book. Interested readers are advised to refer to the literature on this subject, especially that this knowledge is advancing rapidly. Step 2: Activate color Doppler and tilt the transducer to left or right in a parasagittal plane until visualizing the left or right uterine artery, respectively. Screening for fetal anomalies during the first trimester of pregnancy: transvaginal versus transabdominal sonography. Early development of the forebrain and midbrain: a longitudinal ultrasound study from 7 to 12 weeks of gestation. Transvaginal ultrasound measurements of the fetal heart at 11 to 17 weeks of gestation. Transvaginal sonographic diagnosis of congenital anomalies between 9 weeks and 16 weeks, menstrual age. Detailed screening for fetal anomalies and cardiac defects at the 11–13 week scan. Role of first-trimester sonography in the diagnosis of aneuploidy and structural fetal anomalies. Improved detection rate of structural abnormalities in the first trimester using an extended examination protocol. Prenatal detection of congenital heart defects at the 11 to 13 week scan using a simple color Doppler protocol including the 4-chamber and 3-vessel and trachea views. Systematic review of first trimester ultrasound screening in detecting fetal structural anomalies and factors affecting screening performance. First trimester fetal anatomy study and identification of major anomalies using 10 standardized scans. Fetal transabdominal anatomy scanning using standard views at 11 to 14 weeks’ gestation. A model for a new pyramid of prenatal care based on the 11 to 13 weeks’ assessment. The presence of fetal chromosomal aneuploidies has been associated with significant pregnancy complications such as multiple malformations, growth restriction, and perinatal deaths. Prenatal screening for chromosomal aneuploidies has received significant attention over the past 30 years and is now considered an integral part of prenatal care. Advancement in aneuploidy screening has currently led to the prenatal identification of most fetuses with chromosomal abnormalities. Interestingly, one or more of these four findings was found in 53% of all T21, in 72% 1 of all T18, and 86% of all T13 fetuses. In this chapter, we present detailed first trimester sonographic features of aneuploidies in addition to aspects of other genetic diseases and syndromes. This has been one of the most important elements of aneuploidy screening as it resulted in a significant reduction in unnecessary invasive testing on pregnant women with advanced maternal age. Monosomy X was also detected in more than 90% of cases along with more than 85% of triploidies and more than 30% of other 6 chromosomal abnormalities. Additional first trimester findings in T21 fetuses are shown in images in various chapters of this book. Note the various thicknesses of the nuchal translucency (asterisk) and the absence (A, C, F) or poor ossification (B, D, E) of the nasal bone (arrows). Note the presence of early hydrops with body skin edema (white arrows in A and B) and a thickened nuchal translucency (asterisk in A). Note the presence of an atrioventricular septal defect (asterisk) in A and B, which represents the typical cardiac anomaly of this syndrome. Also note the associated body edema (arrows), which resolved at 16 weeks upon follow-up. For physicians and sonographers with expertise in the first trimester ultrasound examination, T18 or T13 is often first suspected by the presence of typical ultrasound features, rather than by biochemical screening. In a study involving 5,613 normal fetuses and 37 fetuses with T18, the first trimester ultrasound examination was found to be a good screening test for 7 7 T18. Note the presence of reverse flow during the atrial contraction phase (A) of the cardiac cycle (arrow). Fetus A had no associated cardiac defect, whereas fetus B had a cardiac defect, which may explain the more severe reverse flow of the A-wave (arrow in B).

Purchase tetracycline with a visa

Obtain clinical specimens (usually stool specimens) from ill case patients for laboratory analysis of enteric pathogens 01 bacteria order 500mg tetracycline visa. When possible, obtain samples of implicated food or environmental samples for laboratory analysis. Hold these samples under refrigeration until a known etiologic agent has been identified. Relate the outbreak to time, place and person If an outbreak occurs following a common meal or exposure. It is imperative to interview non-ill (control) persons who are similar or had similar experiences regarding time and place to those ill. Begin with broad or “loose” definitions that may be narrowed as more cases are defined. Make case counts and relate these to the appropriate population to determine those groups at risk. Contact those with information on the illness or environmental circumstances contributing to the outbreak. When attempting to identify cases, additional contacts may need to be surveyed such as physicians, clinics, hospitals, laboratories and friends of case-patients. In some situations the media may be used to solicit case-patients, but this approach should be considered carefully to avoid biasing an epidemiologic investigation and damaging the reputation of local establishments unnecessarily. Test hypothesis and formulate conclusions Accept or reject the hypothesis on the basis of the available data and appropriate statistical analysis. For a hypothesis to be accepted, the patterns of disease must fit the nature of the agent, its source, its mode of transmission, and the contributory factors that allowed the outbreak to occur. If the hypothesis is rejected, another hypothesis should be developed and additional data gathered in order to test this new hypothesis. A more systematic study can be conducted as needed to improve the sensitivity and specificity of the findings, establish the true number of cases, and assist in arriving at more definitive conclusions. These final reports serve as a record of the rationale and provide documentation for the activities conducted during the investigation. The final report can also be used to improve future investigations and prevention measures. The report should follow the usual scientific format of introduction, background, methods, results, discussion, references and recommendations (See below). The background is a short paragraph describing why the outbreak investigation was initiated and may include who was affected, how many people were ill and how many exposed, where the outbreak occurred, the severity and clinical presentation of the cases. Note whether or not the outbreak involved a particular setting or social event. The methods section should list how cases were identified, how questionnaires were developed, methods used to collect data, as well as clinical and environmental samples, laboratory tests performed, statistical methods. The results section should list what was discovered in the investigation, results of laboratory testing of clinical or environmental samples, results of the epidemiologic investigation, the sanitarian’s report, statistical results, epi-curves, tables, charts and other studies used during the investigation. Could they be instituted in similar outbreaks in the future or how should they be changed? Is the current surveillance program sufficient to identify and control future outbreaks? List any important or unique aspects of the outbreak or a specific disease agent uncovered during the investigation.

Criteria for confirmation of parasitic agents responsible for foodborne and waterborne illness. Criteria for confirmation of other agents responsible for foodborne and waterborne illness. This is especially true for those agents that may only be shed for several days such as Clostridium perfringens, Bacillus cereus or Staphylococcus aureus. It is also important for the laboratory to be notified about these specimens as early as possible because several of these agents require special plating media that may need to be ordered before the samples reach the laboratory. Clinical Samples Collect clinical specimens (usually stools) from ill cases for laboratory analysis of enteric bacteria and viral pathogens. The amount of sample required for bacterial and viral testing is less than for parasites. For parasite testing a walnut-sized portion of stool is submitted in formalin (See Criteria for Confirmation). If the food item was already frozen, hold it in the freezer until a determination can be made about testing. Samples should be labeled with the name of the outbreak or establishment where the sample was collected, type of specimen, time and date of collection, a unique sample number and the investigating official’s initials. All food samples should be held under refrigeration until clinical specimens have been tested. If clinical samples on case patients are negative or not tested, food samples are not tested unless there is compelling epidemiologic evidence incriminating a particular food item. Laboratory procedures for the isolation of microbial foodborne disease agents are complicated and time consuming. It is important the laboratory has good epidemiologic information before analyzing food samples to insure a proper analysis. If the sample being submitted is a commercial food, the name of the manufacturer or processor, code or lot number, and other identifying characteristics are important. If a clinical specimen from at least one ill individual is positive for a foodborne pathogen, food samples should then be transported to the laboratory on ice or under refrigeration as rapidly as possible in order to maintain the population of organisms present. If food kit #32 is not available, an insulated container with frozen kool-pacs or ice cans should be used when shipping samples to the laboratory. Packages received at the local post office by late afternoon or evening must be sent by Overnight Express Mail to guarantee next day delivery. Food samples collected on Friday may be held under refrigeration until the following Monday. With some microbial agents of foodborne disease, it is necessary that large numbers of the organisms be present in a food for it to be hazardous. Examples of these agents would be: 6 Bacillus cereus, Clostridium perfringens and Staphylococcus aureus. Usually 10 organisms per gram of food are necessary before there is a danger of food poisoning from these agents. For these kinds of agents the laboratory reports the number of organisms present per gram of food, and whether or not this would be considered a significant level. With other bacteria, any number of organisms present in a ready-to-eat food may be significant.

Personal Protection: When handling items soiled with blood or body fluids antibiotics history tetracycline 250mg free shipping, use disposable impervious gloves, gowns, masks and eye coverings. Cleaning Procedure: Blood and other body fluids must be thoroughly cleaned from surfaces and other objects before applying this product. Disposal of Infectious Materials: Use disposable impervious gloves, gown, masks and eye coverings. Blood and other body fluids must be autoclaved and disposed of according to local regulations for infectious waste disposal. Table 7 lists the evaluated products that are registered for use in California and claim efficacy against norovirus (aka Norwalk virus), which can cause stomach flu or gastroenteritis. Appendix C: Best Practices for Cleaning, Sanitizing and Disinfecting Surfaces Product selection is only one element of a comprehensive risk reduction strategy for disinfection and sanitizing. Below are our recommendations for best practices relating to the selection, dilution and use of antimicrobial cleaning products. Use disinfectants and sanitizers only on 43 surfaces with high public health significance, where germs (such as flu virus) might be easily transferred to others, or where required by law. If sanitizers and/or disinfectants are needed, public agencies should establish procedures detailing where, when and how they should be used, and ensure that all janitorial staff are properly trained. Products with general disinfecting claims are primarily needed for touch points: Faucets, doorknobs, sinks, toilet seats, railings, and other surfaces frequently touched by building occupants. To kill viruses or fungi, look for disinfectants specifically registered for use against these organisms, since some disinfectants are registered to kill only bacteria. Certain types of facilities have specialized cleaning, sanitizing and disinfection requirements. For example, licensed childcare operations often have specific requirements in diaper-changing and bathroom areas. Similarly, restrooms in correctional or healthcare facilities may fall under specific state or local regulations. Public health regulations usually require surfaces that come in direct contact with food primarily in the kitchen to be pre-cleaned and then treated with a product that is approved for use as a food-contact surface sanitizer. Disinfectants claiming bloodborne pathogen efficacy may be needed if there is an incident resulting in contamination with bodily fluids (such as blood or vomit). Disinfectants that are registered to kill athlete’s foot fungus are appropriate for locker rooms and gym areas. Flu epidemics require products registered for influenza, and more extensive use of disinfectants. Read labels carefully and consider clearly labeling which product is used for each situation. Microbes adhere to organic matter, which means that effective cleaning is usually 123 sufficient to eliminate 80-99% of germs. Surfaces such as mirrors (even restroom mirrors), windows and walls, for example, generally do not need to be treated with sanitizers or disinfectants. Public agencies should consider using microfiber mops and cloths since they are more effective at removing dirt and germs than conventional string mops. Microfiber systems are popular in health care facilities because they minimize transferring microbes from room to room because a new microfiber pad is 129 used in each room. In situations where disinfection is required, a two-step process is ideal: Clean the surfaces first, followed by a U. Although some products are labeled as one-step cleaner-disinfectants, it is not advisable to use them because it is difficult to monitor whether they are being used properly. However, if a surface exceeds that level, the product will no longer be effective. An important first step in developing a cleaning plan is to conduct a baseline assessment of the cleaners, sanitizers and disinfectants that are used on various surfaces in the facility’s restrooms and other areas. It is important to develop an inventory of products currently in use on various surfaces in hallways, restrooms, offices, and other parts of the building. Together, these documents will help users identify many of the important health and environmental risks, as well as the efficacy and dwell time of products currently in use. As a general rule, target for elimination those products containing ortho-phenylphenol, chlorine bleach, quaternary ammonium chloride compounds (quats), peroxyacetic acid, pine oil, and thymol. Compare their efficacy to products containing hydrogen peroxide, citric acid, lactic acid, or caprylic acid and choose an alternative product with the efficacy you need. All antimicrobial products must be left on the surface for the required “dwell time” in order to be effective against the organisms claimed on the label. If a product is wiped or rinsed off before the required dwell time, it is not likely to effectively kill the germs you are trying to target. Some products must also be rinsed off to prevent exposure to building occupants who may touch the residual disinfectant, and to prevent corrosive damage to the surface. Aerosol cans often contain a significant amount of propellant, making the 130 per-unit cost of product high compared to non-aerosol delivery systems. Most propellants have environmental concerns, and the use of aerosol products also increases exposure because the product is delivered in a fine mist, which can easily penetrate the lungs. Because disinfectants need to saturate a surface for 1 to 10 minutes in order to be effective, there is almost no germ-killing benefit from spraying disinfectants or sanitizers into the air. These products are often used to mask odors but result in unnecessary exposure, are generally not effective at killing germs, and can cause or aggravate asthma, adding to any health impacts of the active ingredient or other components. Even better, identify the source of the odor and devise a chemical-free solution such as improved ventilation, if possible. Concentrated cleaning, sanitizing 131 and disinfecting products are the most cost-effective options. Concentrates are also environmentally preferable, since they avoid the need to ship large volumes of water long distances. For these reasons, we recommend closed-loop delivery systems, which are recognizable by the use of sealed bottles that can only be opened once they are fixed to the dilution apparatus. Workers cannot simply open these bottles and pour them into a bucket, and there is no possibility of contact with the concentrates. A poor second choice to closed-loop systems would be measuring pumps, which can be purchased separately and attached to the (unsealed) bottle. Besides protecting workers, dilution systems also make it easy to dilute the product accurately, reducing the likelihood of making solutions that are too strong or too weak, which is the case when concentrates 45 are diluted by hand. Proper dilution can also save money, since users are often tempted to err on the side of stronger solutions. Thymol Antibac Antibacterial Kitchen Cleaner (also called Benefect Method Products, Inc.

The authors should then not use term “correlation” in the objective (last paragraph of introduction section), as well as in the title. Therefore, I highly recommend to change to a more general title, such as “Clinical manifestation of norovirus infection in children aged less than five years old admitted with acute diarrhea in Surabaya, Indonesia: a cross-sectional study” or “Norovirus infection in children aged less than five years old admitted with acute diarrhea in Surabaya, Indonesia: a cross-sectional study”. Previously I was only concerned about electron microscopy, but I just realized that is it true that genogroup diversity can also be determined by immunochromatography? I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.

Reports of norovirus prevalence in children <5 years old with acute diarrhea in Indonesia are still limited. Therefore, this paper is highly important to expand the data of norovirus surveillance in Indonesia. Comments: However, this paper needs a major revision to improve the way of presenting and discussing the data as I recommend the following: 1. The authors should then not use “correlation” in the objective (last paragraph of introduction section), as well as in the title, this does not make any sense. The author can change into a more general title, such as “Clinical manifestation of norovirus infection in children aged less than five years old admitted with acute diarrhea in Surabaya, Indonesia: a cross-sectional study” or “Norovirus infection in children aged less than five years old admitted with acute diarrhea in Surabaya, Indonesia: a cross-sectional study. Norovirus genogroup is based on genetic analysis, so somehow it is weird that it can be differentiated based on electron microscopy. The authors did not perform comprehensive literature searching of the previous norovirus study in Indonesia. In fact, there are already some “key” publications in this field, but the authors did not include them in this manuscript. Please thoroughly check the referenced papers to improve author statement in both introduction and discussion section1-5. In the methods: Are there any specific reason to exclude <1 month baby in this study? The authors mention in discussion: “This agrees with a previous study done in healthy subjects in Surabaya, Indonesia" this is not a match comparison, because the previous study is in healthy, asymptomatic adult subjects. The authors should check the above papers that I recommended for much better comparison of previous studies in Indonesia. In the discussion, the authors should also discuss associated risk factors of contracting norovirus based on Table 2. For example, why did in your population is the most prevalent age of norovirus positive 6-23 months? In conclusion, it is mentioned: “This study demonstrated that norovirus was responsible for 48. If this is not published in a peer-reviewed journal, it would be better to change the reference with one I recommended.
