MCQ on Hepatitis D Virus

Sourav Bio


Hepatitis D, also known as delta hepatitis, is a viral infection that causes liver inflammation. It is caused by the hepatitis D virus (HDV), which is a small, enveloped RNA virus that belongs to the hepatitis virus family. HDV is unique in that it requires the presence of the hepatitis B virus (HBV) to replicate and produce infection. Therefore, HDV infection can only occur in individuals who are already infected with HBV or who are at risk of becoming infected with HBV. HDV is transmitted through contact with infected blood or body fluids, such as through injection drug use, sexual contact, or during childbirth. It is also possible to contract HDV through transfusions of infected blood or blood products, although this is rare in developed countries due to screening of donated blood for hepatitis viruses. The incubation period for HDV is typically 2-6 weeks, and the most common symptom is jaundice, or yellowing of the skin and whites of the eyes. HDV can be prevented through vaccination for hepatitis B and can be treated with antiviral medications.
