Chronic infections are long-lasting infections that can persist for months or even years. Unlike acute infections, which come on suddenly and resolve quickly, chronic infections often develop slowly and can be difficult to treat. They may be caused by various pathogens, including bacteria, viruses, fungi, or parasites, and can lead to ongoing health issues. Common examples of chronic infections include HIV, hepatitis B, and tuberculosis. These infections can remain in the body for extended periods, sometimes without causing noticeable symptoms. Effective management often requires long-term medical care and treatment to control the infection and prevent complications.
