Determinants of Schistosoma mansoni transmission in hotspots at the late stage of elimination in Egypt.

Background: In certain settings, the prevalence and severity of schistosoma infection do not lessen despite repeated rounds of preventative chemotherapy; these areas are known as hotspots. This study aimed to investigate the role of human practices, besides environmental and malacological factors, in the maintenance of the Schistosoma mansoni infection transmission chain in hotspot areas in Egypt.

Methods: This cross-sectional study was conducted between July and November 2019 in Kafr El-Sheikh Governorate, Egypt.
