Quality Assessment of Observational Studies Quality (Risk of Bias) Assessment of Individual Studies Determination of Ratings Studies that had a serious flaw were rated poor in quality, studies that met all criteria were rated good in quality, and the remainder of the studies were rated fair in quality. As the fair quality category is broad, studies with this rating vary in their strengths and weaknesses. The results of some fair quality studies are likely to be valid, while others are only possibly valid. A poor quality study is not valid as the results are at least as likely to reflect flaws in the study design as a true difference between the compared interventions. A serious flaw is reflected by failure to meet combinations of items on the quality assessment checklist; for example, unclear randomization and allocation concealment methods combined with differences between randomized groups at baseline in potentially prognostic characteristics and either high attrition or lack of an intention to treat analysis.

A precise diagnosis can only be achieved by laboratious cause should not be assumed. This is especially important in outbreaks, because of the need to instigate appropriate epidemiologic In the developing world, diarrheal disease is investigations and control measures. In Escherichia coli the developed world it remains a very common complaint, This is one of the most versatile of all bacterial pathogens. Most of the in man and animals (see Chapter 3), whereas others possess pathogens listed in Figure 20. Strains that cause diarrheal disease do so acquired by travellers to these areas and imported into their by several distinct pathogenic mechanisms and differ in home countries. Many cases of diarrheal disease are not diagnosed, either because they are mild and self-limiting and the patient does There are four distinct groups of E. It is generally impossible to distinguish on clinical nization factors, which bind the bacteria to speci?c receptors Diarrheal Diseases 255 Fig. In order to spread to a new microbes or their toxins host, pathogens are excreted in large numbers in the feces and must survive in the environment for long enough to infect another person directly or indirectly through fluids contaminated food or ?uids. These strains are cytic vacuole, multiply and spread to adjacent cells, causing referred to as verotoxin-producing E. Verotoxin receptors have been identi?ed on countries renal epithelium and may account for the kidney involvement. Salmonella Salmonellae are the most common cause of food-associated diarrhea in many developed countries Until recently salmonellae were the most common cause of food-associated diarrhea in the developed world, but in some countries they have now been beaten into second place by campylobacter. However, more recent studies indicate that there is a single species, or at most three species, and that serotypes Fig. These are summarized in Salmonella infection is also transmitted from person to Figure 20. Infections are more common in children and are person and therefore secondary spread can occur, for examoften travel-associated, and these factors should be considple within a family after one member has become infected ered when samples are received in the laboratory. Antibacterial therapy is not indicated for Diarrhea is the most common manifestation E. With the exception of multiply in lymphoid follicles Salmonella typhi, salmonellae are widely distributed in animals, causing reticuloendothelial providing a constant source of infection for man. A similar route of invasion occurs in Shigella, Yersinia and reovirus infections. The vast majority of salmonellae cause infection localized to with particular predispositions (e. Vomiting is rare and fever needed for salmonella diarrhea is usually a sign of invasive disease. Fluid and electrolyte replacement may be required, of approximately 150 cases, with about 70 deaths. Unless there is should be set in context against the approximately 30 000 evidence of invasion and septicemia, antibiotics should be reported cases of diarrhea. Salmonella diarrhea can be diagnosed by culture on selective media Salmonellae may be excreted in the feces forthe methods for culturing fecal specimens on selective media several weeks after a salmonella infection are summarized in the Appendix. The large animal reservoir small numbers may require enrichment in selenite broth makes it impossible to eliminate the organisms and therefore before culture. It is dif?cult, if not impossible, to determine the likely cause of a diarrheal illness on the basis of clinical features alone, and laboratory investigations are essential to identify the pathogen.

As with salmonellae, there is a large animal reservoir of campylobacter in cattle, sheep, rodents, poultry and wild birds. Infections are acquired by consumption of contaminated food, especially poultry, milk or water. Recent studies have shown an association between infection and consumption of milk from bottles with tops that have been 260 Gastrointestinal Tract Infectionsthe clinical presentation is indistinguishable from diarrhea Cholera ?ourishes in communities with caused by salmonellae although the disease may have a longer inadequate clean drinking water and sewage incubation period and a longer duration. The 1990s have witnessed the seventh pandemic of cholera spreading into Latin America, and the disease remains Cultures for campylobacter should be set up endemic in South East Asia and parts of Africa and South routinely in every investigation of a diarrheal America. Asymptomatic human carriers are tant to note that the media and conditions for growth differ believed to be a major reservoir. Growth is often contaminated food; shellfish grown in fresh and estuarine somewhat slow compared with that of the Enterobacteria, waters have also been implicated. Direct person to person but a presumptive identi?cation should be available within spread is thought to be uncommon. Cases still occur in developed countries, but high campylobacter diarrhea standards of hygiene mean that secondary spread should Erythromycin is the antibiotic of choice for cases of diarrheal not occur. Over the past 20 years there have been 66 cases disease that are severe enough to warrant treatment. Serotype O1 is the most important and is further divided into two biotypes: classical and El Tor. The El Cholera Tor biotype, named after the quarantine camp where it was Cholera is an acute infection of the gastrointestinal tract first isolated from pilgrims returning from Mecca, differs caused by the comma-shaped Gram-negative bacterium V. The disease has a long history characcauses only a mild diarrhea and has a higher ratio of carriers terized by epidemics and pandemics. The El introduction of the bacterium by sailors arriving from Tor biotype, which was responsible for the seventh pandemic, Europe, and in 1849 Snow published his historic essay On has now spread throughout the world and has largely disthe Mode of Communication of Cholera. The originated from the El Tor O1 biotype when the latter methods are given in the Appendix. This provided the recipient strain with a selective advantage in a region where a large part of the population is immune to O1 strains. The symptoms of cholera are caused by an enterotoxin sensitive to stomach acid large dose needed to causethe symptoms of cholera are entirely due to the producdisease unless patient tion of an enterotoxin in the gastrointestinal tract (see achlorhydric or taking antacids Chapter 12). However, the organism requires additional virulence factors to enable it to survive the host defenses and adhere to the intestinal mucosa. The severe watery non-bloody diarrhea is known as production of mucinase rice water stool because of its appearance. It is this specific receptors fluid loss and the consequent electrolyte imbalance that results in marked dehydration, metabolic acidosis (loss of massive loss of fluid bicarbonate), hypokalemia (potassium loss) and hypovolemic and electrolytes (no damage to toxin production shock resulting in cardiac failure. Shigella diarrhea is usually watery at ?rst, but later contains mucus and blood Prompt rehydration with ?uids and Shigellae attach to , and invade, the mucosal epithelium of electrolytes is central to the treatment of the distal ileum and colon, causing in?ammation and ulceracholera tion. However, they rarely invade through the Oral or intravenous rehydration may be used. Enterotoxin is produced, but not necessary, but tetracycline may be given as some evidence its role in pathogenesis is uncertain since toxin-negative indicates that this reduces the time of excretion of V. There have, how-the main features of shigella infection are summarized in ever, been reports of tetracycline-resistant V. Lower abdominal cramps can be As with other diarrheal disease, a clean drinking water severe. The disease is usually self-limiting, but dehydration supply and adequate sewage disposal are fundamental to the can occur, especially in the young and elderly. As there is no animal reservoir, it can be associated with malnutrition (see above).

The mechanism of after the consumption of contaminated meat by people pathogenesis is still unclear.

The clinical features of the infections are summarized too long before consumption. The common, enterotoxin-mediated infection (left) is usually acquired by eating meat or poultry that has been cooked enough to kill vegetative cells, but not spores. If reheating before consumption is inadequate (as it often is in mass catering outlets), large numbers of organisms are ingested. Even in the early many other broad-spectrum antibiotics; hence the term days of antibiotic use it was recognized that these agents antibiotic-associated diarrhea or colitis. The infection is affected the normal ?ora of the body as well as attacked the often severe and requires treatment with the anti-anaerobic pathogens.

All plates from cutaneous wounds that have moderate to numerous leucocytes seen in the Gram stain and no pathogen isolated should be reincubated for 5 days to check for Mycobacterium or Nocardia erectile dysfunction drugs in bangladesh purchase 40 mg levitra super active overnight delivery. If a patient has chronic ulcers and nothing has been isolated from previous swabs received impotence gel levitra super active 40 mg buy free shipping, these plates should be reincubated also impotence losartan potassium buy levitra super active in india. Enriched chocolate agar + bacitracin grows Haemophilus influenzae well erectile dysfunction medication causes buy levitra super active 40 mg amex, the bacitracin inhibiting Gram positive organisms erectile dysfunction and diabetes pdf levitra super active 40 mg on-line, though some Haemophilus iufluenzae strains are also sensitive to it. Colistin nalidixic acid agar grows Gram positive, but not most Gram negative, organisms and can be useful with sputa containing enteric Gram negative bacilli and Pseudomonas. In patients where they are likely to be significant, enteric Gram negative bacilli and Pseudomonas can be isolated on MacConkey agar. Feces: Xylose lysine deoxycholate medium relies on xylose fermentation, lysine decarboxylation and production of H2S for primary differentiation of Salmonella and Shigella from non-pathogenic bacteria. Salmonella shigella agar contains bile salts to inhibit Gram positive organisms and coliforms and relies on lactose fermentation for primary differentiation. Liquid specimens, or specimens submitted with a history of food poisoning after ingestion of seafood, should be screened for Vibrio using thiosulphate citrate bile sucrose agar, on which they produce colonies > 2 mm after 24 h incubation. Clostridium difficile agar consists of blood agar + D-cycloserine and cefoxitin, which inhibit almost all other organisms. The organism should be screened for if there is a history of diarrhoea following use of antimicrobials. Urine: Cystine lactose electrolyte deficient medium supports the growth of all urinary pathogens (with rare exceptions), giving good colonial differentiation and clear diagnostic characteristics. The presence of important contaminants, such as diphtheroids, Lactobacillus and Micrococcus, is also clearly elicited, giving an indication of the degree of contamination. It provides a non-inhibitory diagnostic agar for plate culture of urinary organisms. Suprapubic aspirates, ureteric specimens and other urines for which more extensive treatment is warranted may also be cultured onto enriched chocolate agar, anaerobic media and into thioglycolate broth. Genital Specimens: Blood agar will grow most aerobes found in genital specimens, exceptions being Neisseria gonorrhoeae, which grows poorly after 48 h (Neisseria meningitidis grows well after 24 h), and Haemophilus influenzae, which grows poorly unless Staphylococcus is present, in which case satellitism may be observed (note that other organisms also produce satellitism). Enriched chocolate agar + bacitracin should be set up on females less than 10 years old in case of a Haemophilus influenzae infection. New York City medium contains lincomycin to inhibit Gram positive cocci, amphotericin B to inhibit yeasts, and colistin and trimethoprim to inhibit Gram negative bacilli, and is designed to grow only pathogenic Neisseria. Gardnerella vaginalis agar contains nalidixic acid to inhibit staphylococci, amphotericin B to inhibit yeasts and gentamicin to inhibit Gram negative Diagnosis and Management of Infectious Diseases Page 414 Culture bacilli, and grows Gardnerella vaginalis, streptococci and Lactobacillus. The use of a metronidazole disc on the plate will help to distinguish true anaerobes (nearly all sensitive to metronidazole) from facultative anaerobes (resistant to metronidazole). Vancomycin inhibits Gram positives and kanamycin facultative aerobic Gram negatives. Candida albicans will grow and Enterococcus faecalis will sometimes grow on aged media. It was soon realised that characteristics for classification should be as correlated with other characteristics as possible. However, this approach has its problems: real exceptions occur to most characteristics for most organisms, supposed key characteristics may be shared by quite dissimilar organisms while varying for quite similar ones, and slight variation in technique can cause wrong results and wildly incorrect identifications. Numerical taxonomy takes an entirely different tack: testing organisms for a large number of characteristics, each of which is given equal weight, and classifying them in clusters of similarity, which form natural taxons. The 20 or so characteristics chosen for each system were those which had been found to be both highly correlative and most constant for the group of organisms for which the system was designed. These systems now constitute the mainstay of bacterial identifications in the clinical laboratory, but key reactions, many using commercial packages, are also frequently used. For many of those organisms for which no simple packaged system exists, tables and/or keys are available which enable identification. Unfortunately, however, genetic classifications are often not very useful clinically. For example, genetically, Escherichia coli and Shigella should be in the same species. If you know the growth characteristics of an organism, its appearance, smell (if any), perhaps a few key biochemical reactions, likely antibiogram, its usual habitat and the circumstances under which it is likely to be isolated in a clinical laboratory, the identification can be rapid and you are unlikely to be misled into error. Most clinical specimens are seeded to a number of different types of media and it is important to compare the growth on the different media. For example, an organism growing on blood agar but not enriched chocolate agar with bacitracin is probably Gram positive; one growing on enriched chocolate agar with bacitracin but not on blood agar (except, perhaps, as pinpoint colonies) is probably Haemophilus; one growing on blood agar and colistin nalidixic acid agar but not MacConkey is Gram positive; one growing on blood agar, colistin nalidixic acid agar and MacConkey is likely to be either Enterococcus faecalis (tiny colonies) or a Pseudomonas species; one growing on blood agar but not colistin nalidixic acid agar or MacConkey is probably a non-Enterobacteriaceae Gram negative; etc. A Gram positive rod appearing overnight, or even in 48 hours, is definitely not a Mycobacterium. On the other hand, a Haemophilus that takes 48 hours to make a feeble growth on enriched chocolate agar from an eye swab may well be suspected of being Haemophilus aegyptius rather than Haemophilus influenzae. Use of colonial characteristics as a criterion has fallen into disfavour in many identification systems. This is largely because such characteristics are difficult to describe in terms that mean the same to all observers, impossible to include in numerical type taxonomies and even difficult to incorporate into keys and tables. However, many bacteria regularly produce colonies that are typical and almost instantly recognisable, reducing identification procedures to one or two simple confirmatory tests, such as Staphyslide for Staphylococcus aureus and indole for Escherichia coli. Equally, if an identification system gives you an identification which does not accord with the appearance of the organism as you know it or as it is described in the texts, you should seriously question that identification. As proved in a survey with Streptococcus milleri, the smell of the growth of some organisms is so characteristic as to approach an absolutely reliable identification procedure. The Gram stain reaction remains probably the single most correlative characteristic of an organism. This is despite the fact that isolates of some supposedly Gram positive species frequently stain Gram negative. Correlation with the colonial appearance and with the type of media on which the organism is growing may prevent an error in some cases. Also, in many cases, one can learn to recognise microscopically the morphology of species such as Bacillus and Lactobacillus which Diagnosis and Mangement of Infectious Diseases Page 416 Identification of Isolates frequently overdecolorise, and even to detect the minute difference in the appearance of the cell wall in Gram positive and Gram negative species. The potassium hydroxide string test [Place colony in 3% potassium hydroxide and lightly emulsify. Unfortunately, it is not infallible, and Achromobacter, Acinetobacter, Agrobacterium and Moraxella regularly give false negative reactions, while Bacillus species may give a false positive. Where suspicion still exists, vancomycin susceptibility may settle the question; all Gram positives except Lactobacillus, Leuconostoc, Pediococcus and rare strains of Enterococcus are sensitive, while Acinetobacter and Moraxella are the only Gram negatives which may show sensitivity. Again, an oxidase negative and/or large-celled Gram negative bacillus which is penicillin susceptible should be viewed with suspicion unless it has been identified as belonging to a species which includes penicillin susceptible strains. Slow-growing Gram positive bacilli of fine morphology should be subjected to a modified Ziehl-Neelsen stain. The actual morphology of an organism is frequently characteristic and can sometimes be virtually diagnostic. The appearance of cells grown in the presence of a ?-lactam to which they are susceptible (eg, from the zone edge around a penicillin disc) can often be useful in deciding this; cocci tend to enlarge and disrupt spherically, while rods are prone to elongate. Other important properties that can be almost instantly determined are the catalase and oxidase (Kovacs method using a platinum (never nichrome) loop to inoculate an 18-24 hours old colony from a non-selective and non-differential medium to freshly prepared 1% tetramethyl-p-phenyldiamine dihydrochloride (reacts with cytochrome c to form a blue coloured compound; positive reaction must occur in 10 seconds) is the most satisfactory method) reactions. The single most important biochemical characteristic is undoubtedly the O-F reaction. Whether an organism utilises glucose fermentatively, oxidatively or not at all is a highly correlative criterion. It is important to realise that nonfermentative organisms are strict aerobes and vice versa. This is because of the broad groupings, with lack of due notice given to important exceptions; the fact that absolute positive and negative values of characteristics are given at the 85% level, which gives a fairly high probability of encountering an exception; because descriptions of genera are sketchy and sometimes wrong in failing to note important exceptions, while descriptions of species are virtually nonexistent; such basic properties as colonial and cellular morphology are rarely mentioned. So, anyone using Cowan and Steel should check the identification carefully against a description in Balows or Bergey. The tables in Balows are more complete, frequently quote percentages, and are usually accompanied by clear descriptions of species. The problem with Balows is that it largely presupposes enough knowledge to be able to get to the right table. Probably the best scheme for identification of nonfermenting and fastidious Gram negative bacilli is the WeaverHollis scheme. These limitations can arise because the necessary data are not in the data base, because the tests employed have insufficient discrimination for particular organisms, or because a test gives incorrect results. It is always wise to set up the standard extra tests (motility, nitrate, O-F glucose, MacConkey) on any oxidase positive organism; also, any organism which shows only a few reactions after overnight incubation should be reincubated for a further 24 hours and the extra tests set up. For organisms which do not grow on MacConkey or on the usual susceptibility test agars, the addition of a few drops of sterile serum to the saline will improve the test. If no red colouration appears, add a small amount of zinc dust; a red colouration indicates no reduction of nitrate, while no red colouration indicates reduction of nitrate to nitrogen gas. However, failure is usually due to a failure of generated codes to appear in the compendium, rather than of misidentification. Direct identification and susceptibility testing of a suspension of centrifuged organisms from positive blood cultures is possible in many cases (93% accuracy overall); however, it will not work with such organisms as pneumococci, Neisseria and Haemophilus and may give erroneous results for oxacillin sensitivity of Staphylococcus aureus, several antimicrobial agents with enterococci, and ampicillin and cephalosporins with Citrobacter, Enterobacter and Serratia.. On xylose lysine deoxycholate medium, Salmonella appears as distinct black colonies due to H S2 production, and on Salmonella-Shigella agar as clear colonies with some H S2 production. Test first for urease production [converts urea to ammonium carbonate, giving an alkaline reaction; spot test positive in 2 minutes, tube test in 2 hours or less]. A heavy suspension is made of the suspected Salmonella in formal saline from the nutrient agar plate. To drops of this suspension are added 1 drop of polyvalent A-G and/or polyvalent A-S (somatic O antigens), polyvalent H (flagellar antigen) and Vi (capsular antigen) respectively. If polyvalent A-G and/or A-S and polyvalent H are positive and Vi negative, the organism is a Salmonella other than Salmonella typhi and can be further identified by specific agglutinations. If the somatic O antigens are negative, the suspension should be boiled and the agglutinations repeated. If the Vi reaction is positive, boil the suspension for 15 minutes and repeat the agglutinations. Shigella does not ferment xylose and appears as red, sometimes crenated, colonies on xylose lysine deoxycholate agar, clear on Salmonella-Shigella agar. Colonies of Aeromonas hydrophila are large, rhizoid, non-xylose fermenting and oxidase positive. Plesiomonas shigelloides is non-xylose fermenting, oxidase positive, non-haemolytic on blood agar. Diagnosis and Management of Infectious Diseases Page 418 Identification of Isolates Campylobacter is a microaerophilic Gram negative bacillus which grows at 42?C. Rapid hippurate discs are used to differentiate between Campylobacter jejuni (positive) and other thermophilic Campylobacter species (negative). Vibrio grows on thiosulphate citrate bile sucrose agar after 24 hours as ? 2mm colonies (Vibrio cholerae (sucrose fermenter): 2-3 mm yellow; Vibrio parahaemolyticus (lactose fermenter): 3-5 mm green). Fecal isolates are oxidase positive but this cannot be tested from thiosulphate citrate bile sucrose agar as false negatives occur. Colonies of Clostridium difficile on blood agar + cycloserine + cefoxitin agar after 48 hours of anaerobic incubation at 37?C are large, grey, irregular and have a distinctive putrid smell. The organisms can be presumptively identified with > 90% accuracy by a combination of colonial morphology, Gram stain and simple tests (eg. This necessitates the use of a fairly heavy inoculum (usually several colonies), which in turn means that it should be used only where one is reasonably certain of being able to obtain an inoculum consisting entirely of one organism (especially since no purity check will be available when the strip is read). Note particularly that Escherichia coli will give reactions of Shigella if insufficient reaction occurs. Always be suspicious of an identification (in any system) based only on a few characteristics. As long as one is alert to such rarities as Haemophilus in a urethral swab or Pasteurella in a sputum, the vast majority of isolates can be easily identified by the standard methods. The simple scheme below will allow the identification of the great majority of isolates of anaerobes, at least to the degree required. Even here, of course, the vast majority of isolates can be readily recognised by colonial appearance on the different media employed and identified in the usual simplistic manner. Note that both systems have problems with Enterobacter/Klebsiella; in doubtful cases, a motility test may settle the question. Capsular swelling (the swelling of capsule on the surface of the bacterium in the presence of specific antiserum) may also be useful in identifying Klebsiellla. Pseudomonas aeruginosa is usually recognisable by appearance (it commonly produces a green pigment) and distinctive odour. It grows on blood agar, enriched chocolate agar with bacitracin and on MacConkey agar, but not on colistin nalidixic agar.

There are currently no available rapid point-of-care diagnostics to differentiate between bacterial and viral pneumonia; this is a key gap in monitoring the spread of both bacteria and viruses contributing to pneumococcal disease and in providing proper treatment. Vaccines containing proteins common to all pneumococcus serotypes are promising because they could provide broad protection to children worldwide. In addition to radiography and laboratory culture specimen testing, more accurate, robust, and straightforward techniques to count the breathing rate of sick children can help improve specificity for pneumonia. This has the potential to improve the diagnosis and appropriate treatment of pneumonia. These studies have been completed (from 2008 to the latest in 2012), but no study results have been published as to date. Over 90% of this amount went towards vaccines research and development while diagnostics only received 5% of the total funding (see Table 6. New approaches to the genetic manipulation of vaccine candidates can now be considered, including the use of gene rearrangement or genetic recombination of several candidate viral genes. Respiratory synctial virus vaccine development by manufacturers has been affected by the financial risk involved, the high level of investment required, and the low return the investment provides. A possible challenge for such an invention would be an issue of effective usage of the technology. For example, results from malaria studies conducted in Tanzania showed that although point-of-care tests for malaria are more accurate than diagnosis using microscopy, clinicians often ignored both negative results and those patients were still being treated with antimalarial drugs. If pneumonia is combined with hypoxaemia, as happens in 13% of cases, children are five time more likely to die than those with only pneumonia. Even with the availability of novel pneumococcal vaccines, the decision to introduce at the country level is only the first step; storage, transport, education efforts, and health care 6. Such research and development requires constant funding throughout multiple clinical trials in order to get the vaccine on the market and implemented into national immunization programs. There is a need for additional conjugate vaccines, as well as vaccines made of protein antigens that are conserved across pneumococcal serotypes so that an immune response can be generated against all pneumococcal pathogens regardless of their serotype. Research is needed towards the discovery of a pneumococcal vaccine which is immunogenic in all young children as well as the elderly. An ideal vaccine would also protect against pneumococci regardless of their capsular types. Further pharmaceutical gaps lie in the need for rapid diagnostic tools for pneumonia. While X-rays and cultures laboratory tests can confirm the presence of the organism, those diagnostic tools can be costly and time consuming, especially in lower-income and leastdeveloped countries. Moreover, cases of suspected pneumonia cannot be categorized as a bacterial infection or a viral infection without performing the necessary lab cultures. Therefore, there is a need for rapid diagnostic tools to differentiate between a viral or bacterial infection. A quick and accurate point of care tool could aid health-care providers in providing children with proper treatment in a timely manner and help decide whether or not antibiotics are needed. More precise diagnosis would also help reduce antimicrobial resistance through rational and judicial use of antibiotics in treating pneumonia. The goal to reduce incidence and increase prevention lies with access to affordable vaccines and treatments. Health care pharmaceutical technology companies and small and medium enterprises ? Develop low-cost pneumococcal vaccines with room for more production should there be an increase in market demand. Conclusion Over one million children will die before their fifth birthday, nearly all of which are preventable. Prevention by means of vaccination would be most crucial for reducing pneumonia mortality in children under five, while effective (uptake of) antibiotic therapy for the elderly would serve to decrease mortality due to pneumonia in Europe. Community-based management of severe disease could be an important complementary strategy to reduce pneumonia mortality in children under five as well as in the elderly. Pneumonia has a great burden of morbidity and mortality in developing countries, which results in economic and social pressures on families and the country as a whole. Therefore, pneumonia prevention is not only about saving the lives of children, but it is also about preventing illness, hospitalization, and related economic costs. An integrated care management system has proven to be effective in reducing pneumonia mortality by 17% with the available vaccines against Hib and S. Improved rapid diagnostics at point-of-care along with effective antibiotic treatments would aid in the reduction of pneumonia mortality, while wide-scale implementation of pneumococcal vaccines would help prevent incidences of pneumonia worldwide. Moving forward, research institutions, pharmaceuticals, and smalle and medium enterrpises must work alongside government and funders to create initiatives for the development of novel medical devices and biologics. The constant and unpredictable nature of pneumococcal pathogens can outpace technological and drug development, thus it is crucial for researchers and innovators to continue to make progress in research and development of pharmaceuticals and non-pharmaceuticals interventions.

It will exclude patients with recent hospitalization and children with wheeze whose indrawing resolves after bronchodilator therapy.
