"It causes a rise in sea levels, accelerates erosion of coastal zones, increases the intensity and frequency of natural disasters and accelerates the extinction of species," Luis Gomes Sambo, World Health Organization (WHO) regional director for Africa, said. "The impact on human health is even greater."
Climate change, he added, is thought to directly contribute to changes in the geographic distribution of vector-borne diseases such as malaria and epidemics of meningococcal meningitis, Rift Valley fever and cholera in previously unaffected areas.
"For example, the geographic distribution of meningococcal meningitis appears to be expanding from the usual meningitis belt to the southern African region," Sambo said on 7 April during the commemoration of World Health Day in Brazzaville, capital of the Republic of Congo.
"Waterborne diseases and epidemics of acute diarrhoea are rampant in flood situations," he added. The continent has seen extensive flooding across eastern, western and southern regions.
He said WHO would give priority support to African countries to develop the capacity to assess and manage the adverse health impact of climate change.
In terms of health capacity, Africa faces a crisis. For example, it has 14 percent of the world population and 25 percent of the global disease burden - yet it has only 1.3 percent of global health workers.
