News that many health experts have been predicting has finally developed — a new mosquito-borne illness has made its way to US shores.

Human immunodeficiency virus (HIV) is a sexually transmitted disease that can be deadly. HIV infection often goes undetected in patients who do not seek care. However, new research says that there may be new ways to use HIV care so that the virus becomes manageable.

For patients with human immunodeficiency virus (HIV), hepatitis C (HCV) can also be a problem. A new combination of medications, however, may effectively treat HCV in those with HIV.

HIV has been a national concern for years, but new data suggest that serious progress has been made.

According to new research, African-American and Latino people with HIV or AIDS were the least likely to take medication that could extend their lives. Researchers may now have some of the answers as to why.

Details of the passengers on the Malaysian Airlines plane shot down over Ukraine this week are starting to emerge. Among the lives lost were leading HIV/AIDS researchers on their way to the International AIDS Conference in Australia.

HIV can be hard to diagnose early because symptoms can be basic and flu-like. New research identified signs of HIV infection that may help doctors decide which patients need to be tested.

It can be difficult to treat C. diff  infection in people who are immunocompromised, meaning they have a weakened immune system. Researchers now think an increasingly common treatment may be safe for these immunocompromised patients.

One of the few vaccines that can actually protect against cancer is the human papillomavirus (HPV) vaccine, which prevents four strains of HPV. But some parents have expressed concerns about the safety of the HPV vaccine.

Vaccines can be used to protect against both viruses and bacteria. But bacteria have a secret weapon that makes them harder to fight.
