Greek hepatitis B immigrants

Your opinion doesn't hold water. Hepatitis has existed since ancient times, even when there was no America in the world. Besides, Americans have to do it themselves.

As early as BC, the ancient Greek doctor Hippocrates (born about 460 BC) described hepatitis (jaundice).

Our country also recorded the clinical symptoms of jaundice in Huangdi Neijing, such as hypochondriac pain, red eyes, blue face, cheek pain, sore throat and so on. And realize that it is contagious, "damp and heat intersect, and people are sick and jaundice."

At the beginning of World War II, the US military vaccinated more than 2 million people with serum-containing yellow fever vaccine, and 5 1337 people developed hepatitis, with an incidence rate of 10% ~ 15%, and a large number of asymptomatic infected people.
