Infectious Disease

Infectious disease is a medical specialty that focuses on illnesses caused by microorganisms such as bacteria, viruses, fungi, and parasites. These diseases can spread through direct contact, contaminated food or water, insect bites, or airborne transmission. Common infectious diseases include influenza, tuberculosis, HIV/AIDS, malaria, and COVID-19. Infectious disease specialists diagnose and treat these conditions, often using antibiotics, antivirals, or other targeted therapies. They also play a vital role in infection prevention, vaccination, and outbreak control. With global travel and climate change influencing disease spread, managing infectious diseases remains a critical aspect of public health and modern medicine.
