Drug resistance
Drug resistance occurs when a disease-causing organism, like bacteria or viruses, evolves to withstand the effects of medications that once effectively treated them. This happens through mutations or acquiring resistance genes, often due to misuse or overuse of drugs. As a result, infections become harder to treat, leading to prolonged illness and increased healthcare costs. Managing drug resistance involves careful use of antibiotics and antivirals, ensuring patients complete their prescribed courses, and developing new treatments. Understanding and addressing drug resistance is crucial for effective health care and combating infectious diseases.
