infectious disease
Illness caused by microorganisms
An infectious disease is a disorder caused by an organism, such as a virus, bacterium, parasite, or fungus, that invades and infects the body. These organisms can be transmitted through direct contact with infected individuals or their bodily fluids, contact with contaminated surfaces or objects, or through inhalation of airborne particles.
Infectious diseases can range from mild to severe and can affect different parts of the body. Symptoms of infectious diseases can include fever, fatigue, coughing, diarrhea, and rashes, among others. Treatment for infectious diseases can include antiviral or antibiotic medications, rest, and fluids.
Prevention of infectious diseases involves maintaining good personal hygiene, such as regular hand-washing and covering the mouth when coughing or sneezing, and avoiding contact with infected individuals or their bodily fluids. Vaccines are also an effective preventative measure against many infectious diseases.
