Bronchiolitis in Tropical South India

Epidemiology and aetiology of acute bronchiolitis in Hong Kong infants

“…Furthermore, according to the statistics of the Medical and Health Department of Hong Kong collected during 1976-85, the number of in-patients treated in seven government hospitals for acute bronchiolitis and bronchitis was greater in late spring and summer and lowest in winter (personal communication). Although this seasonal distribution is different from that reported from Western countries, similar observations have been reported from Trinidad [25] and South India [26].…”

Acute Respiratory Tract Infections: Epidemiological Data, Guided Case Management and Outcome in a Pediatric Hospital in Riyadh

“…Pneumonia accounted for 4336 patients (73.3% of ALRTI admissions) ( Table 2), which is lower than the 86.5% reported in a Bangladesh study. 24 Bronchiolitis accounted for 1581 patients (26.7% of ALRTI admissions), which is lower than the 35% and 54% reported earlier in South India 25 and Riyadh, 26 respectively. Better immunization, nutrition, socioeconomic and educational status at present could explain the lower incidence of both pneumonia and bronchiolitis in our study, compared to eight years ago when these two studies were performed (from 1985 to 1987).…”

“…The higher male to female ratio (1.4:1) in this study has been reported in other studies. 18,[24][25][26] Although bronchiolitis and pneumonia have been shown in this study to be present throughout the year, there is a clear correlation with the rainy season starting in our area in October through March, with a peak in January (Table 3). This is consistent with earlier studies from other tropical and Western countries.…”

“…[28][29][30] Perhaps the fact that more people remain indoors during this period, resulting in overcrowding, could explain this. 25 The peak season was different in Hong Kong 27 and Bangladesh, 24 possibly because of a different rainy season. The total duration of hospitalization due to ALRTI was 36,774 days.…”

Audit on the Management of Bronchiolitis: A Single Centre Real World Experience in Bangladesh Can We do Better ?

“…Infants younger than 6 months are most severely affected, owing to their smaller, more easily obstructed airways and their decreased ability to clear secretions 2,3 . Bronchiolitis occurs as much as 1.25 times more frequently in males than in females, the exact reason for this difference is unknown [4][5][6] .…”
