The DAA drugs against hepatitis C are taken orally, as tablets, for 8 to 12 weeks. [56] The treatment depends on the type or types of hepatitis C virus that are causing the infection. [57] Both during and at the end of treatment, blood tests are used to monitor the effectiveness of the treatment and subsequent cure. [56]
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer.

Some of the most well known are antiviral drugs widely used to treat HIV/AIDS, hepatitis C and COVID-19. These protease inhibitors prevent viral replication by selectively binding to viral proteases (e.g. HIV-1 protease ) and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles .
Demonstrates presence or absence of virus: Results may be intermittent during course of infection. Negative result is not indicative of absence. anti-HCV: 5–6 weeks: Enzyme Immunoassay for antibodies: Demonstrates past or present infection: High false positive in those with autoimmune disorders and populations with low virus prevalence. ALT ...
Co-administration of nirmatrelvir/ritonavir with certain drugs is contraindicated, including drugs dependent on CYP3A for removal, for which a raised concentration results in serious reactions, or those with potent CYP3A inducers, for which reduced blood concentration of the two main components may result in loss of effect against the virus and ...
A similar process occurs with other types of viruses. The hepatitis B virus, for example, carries its genetic material in the form of DNA, and employs an RNA-dependent DNA polymerase to replicate. Some of the same compounds used as RTIs can also block HBV replication; when used in this way they are referred to as polymerase inhibitors.
Assessments at this visit will include whether the at-risk person or the potential source-person are HIV positive, details around the potential HIV exposure event, including timing and circumstances, whether other high-risk events have occurred in the past, testing for sexually transmitted diseases, testing for hepatitis B and C (nPEP is also ...
