“…Respiratory infections in children generally occur at two times of the year in Bangladesh: during the winter, and late in the rainy season. 59,60 The timing of the second peak is consistent with respiratory infection incidence being at least partly driven by the observed seasonal reduction in cell mediated immunity.…”

“…It is possible that 2010 was an exceptional year of increased RSV activity. Indeed a RSV-associated outbreak was reported from the country in the same year and population based data also suggest yearlong RSV activity in children aged<2 in 2010 [13,26]. The RSV detection rate was lower in 2013 which could be due to the annual variation in the circulation pattern of RSV.…”

“…The RSV detection rate was lower in 2013 which could be due to the annual variation in the circulation pattern of RSV. RSV circulation varies from year to year and there can be large and small epidemics in some countries [23,26]. The median age of the children we enrolled in 2013 was 7 months.…”

BackgroundWe combined hospital-based surveillance and health utilization survey data to estimate the incidence of respiratory viral infections associated hospitalization among children aged < 5 years in Bangladesh.MethodsSurveillance physicians collected respiratory specimens from children aged <5 years hospitalized with respiratory illness and residing in the primary hospital catchment areas. We tested respiratory specimens for respiratory syncytial virus, parainfluenza viruses, human metapneumovirus, influenza, adenovirus and rhinoviruses using rRT-PCR. During 2013, we conducted a health utilization survey in the primary catchment areas of the hospitals to determine the proportion of all hospitalizations for respiratory illness among children aged <5 years at the surveillance hospitals during the preceding 12 months. We estimated the respiratory virus-specific incidence of hospitalization by dividing the estimated number of hospitalized children with a laboratory confirmed infection with a respiratory virus by the population aged <5 years of the catchment areas and adjusted for the proportion of children who were hospitalized at the surveillance hospitals.ResultsWe estimated that the annual incidence per 1000 children (95% CI) of all cause associated respiratory hospitalization was 11.5 (10–12). The incidences per 1000 children (95% CI) per year for respiratory syncytial virus, parainfluenza, adenovirus, human metapneumovirus and influenza infections were 3(2–3), 0.5(0.4–0.8), 0.4 (0.3–0.6), 0.4 (0.3–0.6), and 0.4 (0.3–0.6) respectively. The incidences per 1000 children (95%CI) of rhinovirus-associated infections among hospitalized children were 5 (3–7), 2 (1–3), 1 (0.6–2), and 3 (2–4) in 2010, 2011, 2012 and 2013, respectively.ConclusionOur data suggest that respiratory viruses are associated with a substantial burden of hospitalization in children aged <5 years in Bangladesh.

“…8,9 The two most common causes of ARI in children below 2 years of age are bronchiolitis and community acquired pneumonia (CAP). 10 Prevalence of childhood asthma is substantial and asthma has often been treated as pneumonia and under-diagnosed in developing countries. 11 Bangladesh is no longer any exception of them with low prevalence.…”

Background :_The spectrum of respiratory illness is wide and includes diseases of upper and lower airways, communicable and non-communicable types. The variation in pattern of morbidity mortality of respiratory illness may be affected by different environmental and climatic variation in different parts of the world.Objective : The present study intended to explore the pattern of respiratory illnesses seen in Bangladeshi children admitted with respiratory illnesses.Methods :_The present prospective observational study was conducted in children up to 12 years of age admitted with acute respiratory illness in pulmonology unit of Dhaka Shishu (Children) Hospitalfrom July 2012 to July 2013. All children between the age limit with acute respiratory illness were included in the study. A standardized questionnaire was formulated and pretested. Then the data were collected through interview by using the questionnaire. Data were analyzed using SPSS version 17.Results : Total 1169 patients were admitted under pulmonology unit during July 2012 to June 2013 among them 324(27.7%) were admitted with respiratory diseases. Among the respiratory diseases Pneumonia (71.2%), Acute Bronchiolitis (20.1%), Bronchial Asthma (4.2%) and TB (2.7%) were commonest. Bronchopneumonia, Acute Bronchiolitis, Bronchial Asthma and TB was common among under 5 children and less common after 5 years. Male were predominate in every cases. Majority of respiratory cases were belonged to poor socioeconomic status. Pneumonia (50.7%) and Acute Bronchiolitis (58.5%) cases were found during autumn and late autumn. Asthma was common during late autumn and winter and Tuberculosis was common throughout the year. Mortality was higher among pneumonia cases.Conclusions :_Respiratory illness contributes most common cause of admission in tertiary care pediatric hospital. Bronchopneumonia is still the commonest respiratory disease with leading cause of mortality.Northern International Medical College Journal Vol.9(2) Jan 2018: 308-310
