A gene which protects against malaria increases the risk of HIV

A gene that. Before the incidence of malaria increases the risk of HIV infection by 40%, according to U.S. and British scientists It has always been a myth that people in Africa, the higher the risk of HIV infection. Because the picture of sexual behavior, but also because of the social conditions However, scientists have long assumed that it might be. A genetic cause of the virus in certain communities People of African descent, there are changes in the gene for DARC that affect their ability to fight malaria, but also contribute to HIV infection. Change in this gene, scientists believe. Due to frequent outbreaks of malaria in the region There was a mutation in the gene for the purpose of the prevention of malaria. Such changes in the gene are observed in about 90% of Africans. According to the researchers, these changes explain the origin of most cases of HIV in Africa. Scientists do not volunteer to live in Africa, but analyzed data from a 25-year study by American scientists, the emergence of HIV in different ethnic groups performed. The researchers found that increases in the face of socio-economic differences in people with genetic changes by 40% susceptibility to HIV infection. According to experts, if the people of Africa, there was no change in the gene is approximately 11% reduction in the rate of HIV infection. According to statistics, approximately 24.5 million people in Africa living with the virus and about 2 million people die of it every year.
