in Schistosomiasis in Zambia: 2: Seasonal Cercarial Transmission Potential of
Schistosoma Mansoni in Muchinshi, by M.A. Shehata, Zambia Journal of
Science & Technology, Vol.9, no.2, December 1991, Pg. 1 -- 14.
A 3-year study of cercarial transmission of S. mansoni in Muchinshi - Copperbelt
province was made. Although the transmission took place all year round during
each year period, it was found that in each year there was season of high
transmission for S. mansoni during the warm wet season (November-March) and
followed by season of low transmission during the cold dry season (April -
August). However, a negligible transmission could have taken place during the
hot dry season (September - October). The results together with those of some
supplementary human schistosomiasis studies, throw some light on the dynamics of
transmission under natural conditions and provide a basis upon which to design a
rational control programme using molluscicides.
