At least 33 people have tested positive for HIV in Bangarmau town of Uttar Pradesh after an unqualified medical practitioner injected some of them with an infected syringe, a government official says.

Although the prevalence of HIV/AIDS is low in the country, Bangladesh is still at high risk of the deadly disease spreading due to its demographic transition and easy access to drugs, say experts.

Women who inserted a vaginal ring coated with an anti-AIDS drug once a month were partially protected against HIV infection, researchers said Monday as they released long-awaited results from two large studies in Africa.

People around the world are living longer, but many are also living sicker lives for longer, according to a study.
