An infection is the invasion and proliferation of microorganisms, such as bacteria, viruses, or fungi, in the human or animal body.
These microorganisms can cause diseases by damaging the cells and tissues of the organism. Infections can be transmitted from person to person through direct contact, the air, water, or contaminated food.
The symptoms of an infection can vary depending on the type of microorganism and the area of the body affected. It is important to treat infections properly with medication or therapies to prevent complications and promote recovery.
