Today is #WorldHepatitisDay2022! To honor it let's talk about Hepatitis B.
The Hep B vaccine is now given at birth, but starting *this year* all adults <60 are recommended to get it.
I talked to the CDC's former viral hepatitis lead Dr. John Ward to understand why 🧵

First, what is viral hepatitis?
Viral hepatitis comprises a few different infections caused by viruses Hepatitis A, B, C, D and E. While A and E mostly cause acute disease, the others including B often lead to chronic infection.
HepB in particular is a lifelong infection.

HepB is harmful because chronic infection is a leading cause of liver cancer.
In the US, between 1-2 MM people have chronic HepB. Most are unaware. And while it travels through body fluids, it's so infectious that transmission can happen through casual contact. (Dr. Ward ⬇️)
