mosquitoes again venture to advance through the highlands of East Africa. And with them is the threat of malaria, a possible consequence of global warming.
"We have seen in recent times, epidemic waves in this area," he assured Odiit Amos, head of Pediatrics Mulago Hospital (Kampala, Uganda) until last month.
The head of the Ugandan program to combat malaria, Seraphine Adibaku confirms the occurrence of epidemics in 2007 in Kabale region (2,000 meters). "It's about climate change. Kabale is not as cold as before," he says.
200 kilometers north of Kabale, in the town of Bundibugyo, Yasamu Maate, an octogenarian farmer said "we've never seen before and had no malaria mosquitoes. But now they're here."
The African continent has gained an average temperature of 0.7 degrees in a century. According to experts, this warming can only encourage the spread of malaria, a disease that transmit certain types of mosquitoes can not survive at temperatures below 15 degrees. "
there a direct link between malaria and climate," says Andrew Githeko, the head of a new research unit on "Climate and Human Health established the Research Institute Kenya Medical.
"As climate changes, more and more regions will be susceptible to parasite transmission," he added.
This researcher, a member of the International Panel on Climate has conducted several investigations at the Hospital of Tumutumu (Nyeri, central Kenya) who associate the rise in temperatures with an increase in malaria cases.
This specialist has helped to design a tool for forecasting epidemics depending on rainfall and temperature ranges, which were first used in 2011 in Kenya.
This theory climate however, has been rejected by other scholars, who believe that the evolution of malaria depends more on the efforts of public health and economic investment.
Simon Hay, of the British University of Oxford, has just produced a 'Malaria Atlas' which shows that "there has been no spread of malaria in the last hundred years", but there has been "systematic recall [ the parasite] in the warm in the tropics. "
