Differences in influenza seasonality by latitude, northern India.

ABSTRACT: The seasonality of influenza in the tropics complicates vaccination timing. We investigated influenza seasonality in northern India and found influenza positivity peaked in Srinagar (34.09°N) in January-March but peaked in New Delhi (28.66°N) in July-September. Srinagar should consider influenza vaccination in October-November, but New Delhi should vaccinate in May-June.
