Chronic infection refers to a persistent, long-lasting infection caused by pathogens such as bacteria, viruses, fungi, or parasites. This type of infection can often go undetected for an extended period of time, as symptoms may be mild or intermittent. Chronic infections can lead to various health complications, including inflammation, tissue damage, and organ dysfunction. Treatment for chronic infections typically involves a combination of medications, lifestyle changes, and sometimes, surgery. Researchers study chronic infections to better understand the underlying mechanisms, develop more effective treatments, and prevent long-term consequences for patients.
