Structural heart disease is very common in HIV patients. It's possible that the conditions are directly related.

Patients with the hepatitis C virus (HCV), which primarily affects the liver, face a higher chance of getting diabetes. Antiviral HCV medication, however, may improve diabetes outcomes.

If there was a vaccine that could possibly prevent cancer, everyone would get it — right? The answer is more complicated than that, as a new study focusing on HPV vaccination showed.

Sometimes it's easy to forget how common many diseases were before vaccines for them were introduced. When the disease is not around, people may not notice as much.

New advancements in HIV treatment have allowed many people to live with a very small amount of the virus in their bodies. But what are the pros and cons?

It used to be that smoking and drinking alcohol were the biggest risk factors for cancers that develop in the mouth and throat. Those trends may be changing, according to a new study.

Many assume that once patients are diagnosed with a disease, they automatically begin receiving treatment for that condition — but researchers behind a new study warning that this may not be the case for many patients with hepatitis C.

Some people with hepatitis C experience serious side effects from or do not respond to interferons, the typical treatment for the disease. Fortunately, new research has shown promising results for a different type of treatment.
