Influenza activity in Kenya, 2007-2013: timing, association with climatic factors, and implications for vaccination campaigns.

ABSTRACT:

Background

Information on the timing of influenza circulation remains scarce in Tropical regions of Africa.

Objectives

We assessed the relationship between influenza activity and several meteorological factors (temperature, specific humidity, precipitation) and characterized the timing of influenza circulation and its implications to vaccination strategies in Kenya.

Methods

We analyzed virologically confirmed influenza data for outpatient influenza-like illness (ILI), hospitalized for severe acute respiratory infections (SARI), and cases of severe pneumonia over the period 2007-2013. Using logistic and negative binomial regression methods, we assessed the independent association between climatic variables (lagged up to 4 weeks) and influenza activity.
