The virus has a double effect, not only arousing fat cells, but also preventing them dying and being sent out of the body. The affected cells then accumulate, leading to obesity. In a study using samples of healthy tissue from 80 women, four out of five who were overweight had the virus – against just one in five who were a normal weight.
