WTF. I am a hepatitis B and Hepatitis D chronic active patient.
There is a plethora of medication for hepatitis B treatment and cure. There is a cure for Hepatitis C as well.
But there is no cure for Hepatitis Delta yet. Even Pegylated Interferon works on about 20% of the patients and that's with dual therapy alongside Telbivudine. Of course after treatment you relapse.
