About

This study aims to determine the prevalence of taeniosis and (neuro)cysticercosis in two districts in the southern (Gwembe) and eastern province (Chipata) of Zambia.

Full description

The true prevalence of Neurocyticercosis in Zambia is not well known. Only one study which was a pilot study done in Katete district of eastern province demonstrated the prevalence of NCC among people with epilepsy. There is need to provide an accurate estimate of the prevalence of NCC among people with cysticercosis in Zambia as well as understand the clinical manifestations of the disease in humans. Data on the full range of clinical characteristics of NCC is essential to accurately estimate the burden of the disease in the community.

The epidemiology work package within the human health sector will create awareness of the size of the problem by delivering scientifically generated prevalence data on TSCT and NCC in various population groups (adults, children, and those living with epilepsy) in two provinces of Zambia. This will form an essential prerequisite for the development of public health policy guidelines for the control/elimination of TSCT/NCC in the country.

Further, environmental factors that could play a role in the transmission and maintenance of T. solium eggs will be studied. This will provide essential data in understanding the epidemiology of the parasite in endemic regions.
