An infection is a condition caused by the invasion and multiplication of harmful microorganisms, such as bacteria, viruses, fungi, or parasites, within a host organism.
These pathogens disrupt the normal functioning of the body, leading to various symptoms and potential damage to tissues. Infections can occur in different parts of the body, ranging from localized skin infections to systemic illnesses affecting multiple organs.
Proper medical treatment, often involving antibiotics or antiviral medications, is essential to combat infections and restore health. Prevention measures, such as vaccinations and hygiene practices, play a crucial role in minimizing the risk of infections.
