Didier Drogba, the Chelsea footballer, said yesterday that he still had not fully recovered from his bout of Malaria. He suffered with headaches and a fever for a month before he was diagnosed in September last year and although he was immediately treated he was sufficiently debilitated by the virus to still feel that he has not yet fully recovered.
This comes in the week that doctors have released new research about the malaria parasite which shows that it is not as effective at infecting its host if that host has a different body clock.
Scientists at Edinburgh University gave the parasites "jet lag" by injecting them into mice whose body clocks were different from their own 24-hour cycle.
The research allows scientists to know when the parasites are at their most infectious and will lead to improved methods of treatment to combat the debilitating, and potentially fatal, virus.
