Infectious diseases are illnesses caused by pathogenic microorganisms—such as viruses, bacteria, fungi, and parasites—that invade and multiply within the body. They can spread through direct contact, contaminated food or water, insect bites, or airborne transmission, affecting individuals and populations worldwide. Research in infectious disease science explores pathogen evolution, immune system responses, antimicrobial resistance, and vaccine development. From global health challenges like influenza, HIV, malaria, and COVID-19 to emerging zoonotic threats, scientists aim to understand how infections arise and spread to develop effective treatments, preventive strategies, and public health interventions that safeguard humanity against future outbreaks.
