Abstract
Malaria is caused by protozoan parasites of the genus Plasmodium. It is one of the
leading causes of illness and death and one of the most important causes of human
morbidity and mortality with enormous medical, economic and emotional impact in the
world. Estimates indicate that there were about 207 million cases of malaria and an
estimated 627 million deaths. Nyamira North District lies in the western Kenya highland
and is known to be a malaria epidemic area with unstable transmission of varying
seasonality. The highest peak of malaria transmission is usually reached between May -
July and November-January periods preceding the short and long rain seasons. The
current study aims to investigate the correlation between environment and household's
knowledge, attitudes and practices with malaria epidemics in Nyamira North District.
890 participants of all ages (all-age cohort) from the study area will be enrolled. Data on
environmental, socio-demographic, and economic factors will be collected from
21villages systematically selected. Environmental data will be collected from Olobal
Positioning System (OPS) measurements. The dwelling in which the participant
normally sleep will be assessed and distances to mapped forest edge, swamps, rivers,
roads, and health centers will be calculated. Type of vegetation within 200 m of the
house will be recorded. The presence and type of slope will also be determined. A
questionnaire will be orally administered to ascertain socio-demographic, economic and
behavioral characteristics. To establish whether there is any statistical relationship
between the mentioned variables and malaria prevalence, Pearson Chi- square test
will be used. An association between the two variables will be considered significant if
the p value~0.05. Data generated by the study will be used by the Ministry of health in
future control strategies for highland malaria in Nyamira North district.
