Infectious diseases are illnesses caused by harmful microorganisms, such as bacteria, viruses, fungi, or parasites, that invade the body and disrupt its normal functions. These diseases can be spread through direct contact (e.g., person-to-person or animal-to-person), indirect contact (e.g., contaminated surfaces or objects), or vectors such as mosquitoes. Symptoms range widely depending on the type of infection and can include fever, fatigue, cough, diarrhea, rash, or more severe complications like organ damage. Common infectious diseases include the flu, tuberculosis, malaria, and COVID-19. Effective management involves diagnosis, appropriate treatment (e.g., antibiotics, antivirals), and preventive measures like vaccination, hand hygiene, and safe food and water practices.
