Direct-acting antivirals

Direct-acting antivirals (DAAs) are medications designed to specifically target and inhibit the replication of viruses, particularly those that cause chronic infections like hepatitis C. Unlike traditional antiviral treatments that may affect the entire immune system, DAAs focus on specific stages of the virus's life cycle, making them more effective and often with fewer side effects. They can significantly reduce the amount of virus in the body, potentially leading to complete recovery. DAAs have transformed the treatment landscape for viral infections, offering shorter treatment durations and higher success rates compared to older therapies.
