Prevalence and Factors Responsible for Asymptomatic Malaria Reservoir of Plasmodium Falciparum Among Adults in Nasarawa State, Nigeria
Abstract:
Asymptomatic malaria is prevalent in highly endemic
areas of Africa, with only a small percentage of individuals exhibiting
clinical symptoms. The clinical consequence of asymptomatic malaria is not
fully understood. Some researchers are of the view that asymptomatic
parasitaemia is involved in the development of partial immunity and may protect
against clinical disease from new infections. The purpose of this study was to
assess the prevalence of malaria reservoir of plasmodium falciparum among adult
people of Nasarawa state of Nigeria and to identify the factors associated with
malaria in this category of people. A community-based cross-sectional
study was conducted among selected local government areas of the state. The
outcome variable was the presence or absence of malaria in which its
asscoiation with demographic information, knowledge and awareness, measures and
control, environmental factors are tested. The local government areas were
observed to have reported the highest positivity rate of malaria between 2017
to 2022. The study was conducted from August 2022 to April 2023. A
semi-structured questionnaire was employed to collect socio-demographic data
and other associated risk factors by trained health professionals. Body
temperature and other clinical manifestations were examined to identify the
asymptomatic individuals. This examination was carried out after selection of
individuals from households before mRDT is conducted. Data entry and analysis was
carried out using SPSS (Statistical Package for the Social Sciences) version 20
software. The results obtained are very desirable.
