Malawi is faced with a high burden of disease with malaria as one of the top contributors to this burden. Health which is a capital stock may be expected to positively contribute to an individual’s decision to participate and supply labour. The decision may in the end have some positive impact on the economy in general. The study assessed the impacts of malaria on household agriculture labour supply in Malawi and examined the effect of malaria on the decision to participate in household agriculture labour supply. The study used the integrated household survey 3 (IHS-3) data collected by the National Statistics Office (NSO) of Malawi in 2010/2011 and employed the Heckman model. Findings from the research reveal that malaria illness affects the decision of an individual on whether to participate in household agriculture or not but not the actual number of labour hours supplied to household agriculture. Other variables such as location (rural) and gender (female) were found to have a significant impact of the number of labour hours supplied to household agriculture. In terms of the decision to participate in household agriculture, factors such as age, education, marital status (married), location (rural), and household size were found to be significant. The main conclusion drawn from this study is that malaria has no significant impact on household agriculture labour supply in Malawi.
