antiviral resistance

Antiviral resistance occurs when viruses change in a way that makes antiviral medications less effective or ineffective. This can happen through mutations in the virus's genetic material, allowing it to survive despite treatment. As a result, the virus can continue to replicate and spread, potentially leading to prolonged illness or outbreaks. Using antivirals improperly, such as not completing a prescribed course, can contribute to resistance. Monitoring and managing antiviral resistance is crucial in healthcare to ensure that treatments remain effective and to control the spread of resistant viral strains.
