Infection

An infection occurs when harmful microorganisms such as bacteria, viruses, fungi, or parasites enter the body and multiply, causing illness or health issues. These microbes can invade tissues, trigger the immune system, and result in symptoms like fever, fatigue, or pain. Infections can be spread through contact with contaminated surfaces, bodily fluids, or close contact with infected individuals. Treatment often involves medications like antibiotics or antivirals, and prevention includes good hygiene practices, vaccinations, and sanitation. Recognizing and managing infections early helps prevent complications and supports recovery.
