Acute respiratory infections (ARIs) in spite of being the single most important under-five morbidity have not been studied adequately in peri-urban settings in India. We conducted this study prospectively on a cohort of 106 children in a peri-urban area of Delhi. The overall 2-week prevalence of all types of ARI was 34.3%. Annual combined incidence of all types of ARI was 7.9 episodes/100 child-weeks; while that for no pneumonia, cough, and cold, pneumonia, and otitis media was 7.1, 0.85, and 0.09 epi/100 ch-wks, respectively. Incidence of ARI was higher in infancy (9.4 epi/100 ch-wks) as compared to toddlers (7.0 epi/100 ch-wks). Pneumonia incidence was higher among boys (0.9 epi/100 ch-wks as compared to 0.6 for girls) and the highest in infants under 2 months of age (1.09 epi/100 ch-wks; < 0.01). Incidence of severe pneumonia was roughly one-tenth that of pneumonia. Incidence of both ARI and pneumonia peaked in spring and autumn. Mothers of infants, zespecially those under 2 months of age, need to be made aware of ARI/pneumonia and IEC campaigns may be aired more intensively keeping their peak season in mind.
