Is hepatitis B blood on clothes still infectious after 10 days?
Blood from hepatitis B on clothing for 10 days—under normal circumstances, after 10 days the blood has likely dried, and the risk of transmission decreases.
The hepatitis B virus exists in bodily fluids such as blood, serum, and semen. It can be transmitted from an infected pregnant woman to her fetus through the bloodstream or during childbirth via the mother's blood and bodily fluids. The virus can also spread through blood exposure, such as blood transfusions, surgical procedures, or sharing needles for drug injection. Generally, the hepatitis B virus can survive for several days in a dry environment; therefore, if the blood on the clothing has dried, the risk of transmission is reduced. However, if the blood on the clothing remains wet, or if there are open wounds or damaged mucous membranes during contact with the clothing, transmission of the hepatitis B virus is still possible.
To prevent the spread of hepatitis B, avoid contact with others' blood and bodily fluids, maintain personal hygiene, avoid sharing personal care items, and receive the hepatitis B vaccine. If infection with the hepatitis B virus is detected, prompt treatment should be sought to prevent further transmission to others.
