What is hepatitis B?
Hepatitis B is a vaccine-preventable inflammation of the liver caused by infection with the hepatitis B virus. Transmission can take place from mother to child at birth, through sexual contact or contact with blood (RIVM, 2021). Hepatitis B is not spread through food or water, sharing eating utensils, breastfeeding, hugging, kissing, hand holding, coughing, or sneezing.
What is the window period for hepatitis B?
Every STI has a window period. This is the time between when an individual is infected and the moment that the STI is detectable with a test. The window period of hepatitis B is four weeks.
When should I consider taking a hepatitis B test?
If you are experiencing symptoms or have had unprotected sex, shared a toothbrush, or shared a needle with someone who has hepatitis B, you should get tested.
Additionally, many people with acute hepatitis B do not have any immediate symptoms. You may already have the virus and be contagious before experiencing any symptoms, or remain infected for an extended period without experiencing any symptoms at all. Individuals infected with hepatitis B remain contagious until the virus is cleared from their body, usually 4 to 8 weeks after onset. In some cases, acute hepatitis B will not be cleared by the body and progress to a chronic infection. This is why screening for hepatitis B as a part of routine STI screening is also recommended. Testing allows you to prevent further spread of the virus and access appropriate treatment if needed.
