Hepatitis B: Explained

As the most common liver disease in the world, Hepatitis B is a life-threatening liver infection caused by the hepatitis B virus, or HBV. It can cause chronic infection and put people at a high risk of death from cirrhosis (scarring of the liver) and liver cancer. In 2015, 257 million people were living with a chronic form of hepatitis B, and almost 900,000 people died from it. In this video, you’ll learn a bit about the background of hepatitis B, its symptoms, transmission, molecular mechanism, prevention, and treatment!

I have a question, i recently visited a salon which required underarm shaving before using diode/razor and i assumed that they didnt use a sterile razor. I checked my undermarm after and there were no nicks and cuts. Can I still get HBV/Hep C and HIV after that?? Im very anxious right now

[everythingyouneedtoknowabo]

I'm inactive hepatitis B carrier with very low viral count, and I'm 21. So is there any chance that my body will git rid of those viruses completely over the period of time.

[greeshmamahadev]

Sir which protein is responsible for this disease?

[car_go_vroom_vroom]

I decided to look into the virus because after receiving the vaccine at birth & now three rounds of the vaccine again I have yet to develop any antibodies or immunity.

[johnj.reeser]

Finally I'm free from this disease Dr Oyetoro continues doing the good work God will surely see you through in everything you do
