Cost-benefit analysis
KCM MCM Zambia Sugar
As shown in Figure 2.5, there is a positive correlation (coefficient = 93%) between costs (money spent
by companies to prevent malaria) and benefits (reductions in health-care costs and worker absenteeism
and productivity due to reductions in malaria cases). While causality cannot be ascertained in
this retrospective analysis, the company malaria control efforts appear to have been an important
driver of the observed effects.
