Hepatitis b study tests if 'Undetectable equals Untransmissible' holds true for body fluids

This study looks at whether people with chronic hepatitis B who have undetectable virus levels in their blood also have undetectable levels in other body fluids like saliva or semen. Researchers will compare treated patients with suppressed virus to untreated patients with active virus. The goal is to see if the 'Undetectable = Untransmissible' message, already used for HIV, can apply to hepatitis B, which could reduce stigma and fear of transmission.
