👉 Medical infection, also known as infection, is a condition where harmful microorganisms such as bacteria, viruses, fungi, or parasites invade and multiply within the body, causing disease. This invasion can occur through various routes, including respiratory droplets, contaminated food or water, or direct contact with infected surfaces or individuals. Once inside, these pathogens can disrupt normal bodily functions, leading to symptoms ranging from mild discomfort to severe illness. The body's immune system responds by fighting the infection, but if the pathogen is too virulent or the immune response is weakened, the infection can escalate, potentially resulting in complications such as sepsis, organ failure, or chronic conditions. Effective treatment often involves antibiotics for bacterial infections, antiviral medications for viral infections, antifungal agents for fungal infections, and supportive care to bolster the body's defenses. Preventive measures, including hygiene practices, vaccination, and proper medical care, are crucial in managing and reducing the risk of infection.
