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]
In the past nucleic acid tests have mainly been used as a secondary test to confirm positive serological results. [3] However, as they become cheaper and more automated, they are increasingly becoming the primary tool for diagnostics and can also be use for monitoring of treatment of viral infected individuals t.
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.

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 ...
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 ...
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 .
Nitazoxanide alone has shown preliminary evidence of efficacy in the treatment of chronic hepatitis B over a one-year course of therapy. [17] Nitazoxanide 500 mg twice daily resulted in a decrease in serum HBV DNA in all of 4 HBeAg-positive patients, with undetectable HBV DNA in 2 of 4 patients, loss of HBeAg in 3 patients, and loss of HBsAg in one patient.
