Study area
This study was conducted in Nakuru, Elgeyo Marakwet and Nandi Counties
in the Rift Valley region. The sites in which the study was implemented
include three district hospitals and one sub-district hospital (Figure
1). The sentinel sites were selected purposively due to the paucity of
information regarding respiratory infections in these counties and their
contributions to the healthcare burden in Kenya. A temperate climate
characterizes the study location with an altitude ranging between
2000-2500m above sea level.
