Abstract
Background: The role of viruses in pediatric pneumonia remains poorly studied in sub-Saharan Africa, where pneumonia-associated mortality is high. Methods: During a 1-year hospital-based surveillance, a nasopharyngeal aspirate (NPA) was collected from children aged Plasmodium falciparum parasitemia, and HIV. Results: Almost half (394/807) of the children hospitalized with clinically severe pneumonia had at least one respiratory virus detected. A total of 475 viruses were detected among these 394 children, the most prevalent ones were rhinovirus (41%), adenovirus (21%), and respiratory syncytial virus (11%). Eleven percent of viral infected children had concomitant IBI, 15% had malaria parasites, and 25% had HIV coinfection. Viral infection was 5.5 to 16 times more prevalent among HIV-infected children and incidence rate ratios varied according to virus. Inhospital mortality of viral cases was 9%, being highest among cases with IBI coinfection (odds ratio = 7) or HIV infection (odds ratio = 7). Conclusions: Study results highlight the high prevalence of respiratory viruses among hospitalized pneumonia cases in Mozambique. HIV infection is an important contributor to the high burden of disease and associated mortality of viral pneumonia. IBI also contributes to a worse prognosis of viral cases. Strategies to prevent mother-to-child transmission of HIV as well as introduction of Hib and pneumococcal vaccines could have a substantial impact on reduction of viral pneumonia and associated mortality among children in rural Africa.Keywords
