A systematic review and meta-analysis show a decreasing prevalence of post-stroke infections.

Background: Infection is a common complication in the acute phase after stroke; a systematic review in 2011 reported a post-stroke infection prevalence of 30%. Despite the plethora of primary data on post-stroke infections in recent times, a systematic review that synthesizes the data to provide comprehensive information to guide preventive, control, and management efforts is yet to be undertaken. This systematic review, therefore, aimed at bridging this gap by describing the epidemiology of post-stroke infections including the global prevalence and the associated mortality rates.
