This infection can cause a variety of health complications and can even be deadly in some cases. It is estimated that over 257 million people worldwide are chronically infected with HBV, making it one of the most common viral infections globally.

The virus is spread through contact with bodily fluids, including through sexual contact, using contaminated needles, or coming into contact with blood or other bodily fluids of someone who is infected. Symptoms of Hepatitis B include yellowing of the skin and eyes (jaundice), tiredness, fever, dark urine, and abdominal pain. It is possible to have this virus without having any symptoms at all though, which means that it is important for everyone to be tested if they think they may have been exposed to the virus. 

Hepatitis B can usually be prevented with a vaccine. The Centers for Disease Control recommends that all children get their first dose of the hepatitis B vaccine soon after birth and complete the three-dose series as recommended by their healthcare provider. Additionally, adults who are at increased risk should also be vaccinated against this virus. 

It’s important to understand that while there is no cure for Hepatitis B once it has been contracted, there are treatments available that can help manage the infection and reduce the severity of symptoms. Treatment may involve antiviral medications or immunosuppressants to control your immune system’s response to the virus. Your doctor will work with you to develop a personalized treatment plan that best suits your needs. 

If you think you may have been exposed to Hepatitis B, speak with your doctor right away so you can discuss testing and possible treatment options available to you. Together you can take steps towards managing this infection so you can live a healthy life despite being infected with HBV.
