Which of the following hepatitis virus in non enveloped naked virus?
Many ‘non-enveloped’ viruses, including hepatitis A virus (HAV) , are released non-lytically from infected cells as infectious, quasi-enveloped virions cloaked in host membranes.
Is hepatitis B virus a retrovirus?
The life cycle of Hepatitis B virus is complex. Hepatitis B is one of a few known non-retroviral viruses which use reverse transcription as a part of its replication process.
Where is hepatitis A found?
What is hepatitis A? Hepatitis A is a virus that causes liver disease. Hepatitis A virus is found in the stool (poop) and blood of infected people .
