“…Health capital determines individuals' labour productivity (Bridges & Lanson, 2011;Novignon et al, 2015;Straus & Thomas, 1995;Thomas & Straus, 1997) and labour participation (Lavy et al, 1995;Handa & Neitzert, 1999as cited in Bridges & Lanson, 2011. Poor health could reduce one's hours of labour supply or days worked (Pitt & Rosenweig, 1986;Ulimwengu, 2009), and one's health status has a significant impact on his/her participation in labour wages (Straus &Thomas, 1995;Mwabu, 2008;Novignon et al, 2015). Extended periods of illness are highly likely to have a negative impact on one's ability to supply labour and could affect the household's productivity (Ulimwengu, 2009).…”
