Communicable diseases in Zambia
Communicable diseases along with maternal, perinatal and nutritional conditions in Zambia accounted for an estimated 64 per cent of all mortality in 2008. The prevalence of HIV in Zambia, as a percentage of population aged 15-49 years, stood at 12.7 per cent in 2012. There has been a gradual and continuous decline in the prevalence of HIV since 1993. There were 2,976,395 reported cases of malaria in 2009. The number of deaths from malaria have fallen by around one-third in the decade 2001-11. In the period 1996-2012 there was a reduction of over a third in the estimated incidence of tuberculosis (TB). Estimated mortality (when mortality data excludes cases co-morbid with HIV) from the disease showed a decline in the period 1990-2012, more than halving over this time. In 2009 there were 4,702 reported cases of cholera, 681 reported cases of pertussis (whooping cough) and 371 reported cases of leprosy.
