HIV-Infected More Prone to Malaria Agence France-Presse Paris - People with HIV may be twice as likely to catch malaria compared to people who do not have the AIDS virus, according to the first research to confirm a link between the two diseases, reported in the Sept 16 issue of The Lancet. The researchers monitored 484 people who visited a rural clinic in Uganda from 1990 and 1998, where their temperature was taken and blood monitored for any malaria parasites and for a count of CD4 cells the white blood cells that are unleashed by the immune system in response to an invader. Malaria infection was found among 11.8 percent of individuals with the AIDS virus, compared with 6.3 percent among people who were HIV-negative.
