Popa,
“Hepatitis B is not common among our community, for good reason.”
Sorry, but I just had a patient the other day who was positive for Hep B. What if I had not been vaccinated and had been exposed? I live in a typical frum community. Easy to pass it around.
Hep B can be spread many ways. People in the frum world work every day with non-Jewish people. People have contact with their car mechanic, gas station attendant etc etc. So to say that frum people are never exposed to these diseases is highly inaccurate.
