According to health officials in the US, HIV infections among needle drug users have fallen by 50 percent since the 1990s. This was found out in a study by the Centers for Disease Control and Prevention.
Researchers tested more than 10,000 drug users from 20 urban areas in 2009. One in ten were tested HIV-positive whereas in the 1990s it was still one in five.
The bad news is, however, that rates of HIV testing among drug users were falling.
