Which of the following statements is TRUE according to the passage?
Scientists say they have proven what they have long suspected about HIV, the virus that causes the disease AIDS. They found that an infected person who has a low amount of HIV in the blood is less likely to pass the virus to someone of the opposite sex.
The study is the largest ever to examine the link between viral level in a person’s blood and the risk of passing HIV through sex. The findings suggest that reducing the amount of the virus in a person’s blood may be one way to slow the rate of AIDS infections. The researchers found that having other sexually transmitted diseases did not affect the risk for HIV. The amount of virus in the blood did affect the risk for HIV.
Experts say the Ugandan study may lead to new treatments to prevent the spread of HIV. But the study has caused criticism about the way AIDS research is carried out. Doctor Marcia Angell, the editor of the blew England Journal of Medicine that published the study, says the HIV-infected people in the study should have been offered anti-viral drugs that are given in industrial countries. She and other people fear that AIDS research is carried out unfairly in poor countries.
