Evaluation of the acute flaccid paralysis (AFP) surveillance system in Mwenezi district, Masvingo, 2018: a descriptive study.

The main reasons for failure to report a case in 2017 were the vastness of the district with bad road networks as well as lack of a dedicated vehicle to carry out EPI outreach activities. About a quarter, 24%, of the health workers did not know the specimen that is used in AFP diagnosis. The AFP surveillance system in Mwenezi district was performing poorly due to lack of active search of cases in the community caused by disruption of EPI outreach activities.
