Abstract
BACKGROUND:
Influenza and respiratory syncytial virus (RSV) infections are responsible for substantial global morbidity and mortality in young children and elderly individuals. Estimates of the burden of influenza- and RSV-associated hospitalization are limited in Africa.
METHODS:
We conducted hospital-based surveillance for laboratory-confirmed influenza- and RSV-associated severe acute respiratory illness (SARI) among patients of any age at one hospital and a retrospective review of SARI hospitalizations in five hospitals situated in Antananarivo during 2011-2016. We estimated age-specific rates (per 100,000 population) of influenza- and RSV-associated SARI hospitalizations for the Antananarivo region and then extrapolated these rates to the national level.
RESULTS:
Overall the mean annual national number of influenza-associated SARI hospitalizations for all age groups was 6,609 (95% CI: 5,381-7,835-rate: 30.0; 95% CI: 24.4-35.6); 4,468 (95% CI: 3,796-5,102-rate: 127.6; 95% CI: 108.4-145.7), 2,141 (95% CI: 1,585-2,734-rate: 11.6; 95% CI: 8.6-14.8) and 339 (95% CI: 224-459-rate: 50.0; 95% CI:36.3-74.4) among individuals aged <5, ≥5 and ≥65 years, respectively. For these same age groups, the mean annual number of RSV-associated SARI hospitalizations was 11,768 (95% CI: 10,553-12,997-rate: 53.4; 95% CI: 47.9-59.0), 11,299 (95% CI: 10,350-12,214-rate: 322.7; 95% CI: 295.6-348.8), 469 (95% CI: 203-783-rate: 2.5;95% CI: 1.1-4.2) and 36 (95% CI: 0-84-rate: 5.8; 0.0-13.5), respectively.
CONCLUSION:
The burden of influenza- and RSV-associated SARI hospitalization was high among children aged <5 years. These first estimates for Madagascar will enable government to make informed evidence-based decisions when allocating scarce resources and planning intervention strategies to limit the impact and spread of these viruses.
