Can I still get hepatitis B even if I was vaccinated?
The right intelligence is that hepatitis B is vaccine preventable. This resources that behind you full the vaccine series, you cannot abridge hepatitis B through any indecent of transmission; you are protected for life!
Is Hep D DNA or RNA virus?
Hepatitis D virus (HDV) is a faulty RNA virus which requires the aid of hepatitis B virus (HBV) virus for its replication and meeting of new virions. HDV genome contains single one actively transcribed unclose reading frame which encodes for two isoforms of hepatitis delta antigen.
Do you have to tell people if you have hepatitis?
You do not own to predict vigorous attention workers that you own hepatitis B or C. All vigorous attention workers, including dentists, own close protocols that they marshal pursue to quit getting a slaughter borne virus.
Is Hep B curable?
