What Role Do Microorganisms Play in Infectious Diseases?
Microorganisms are responsible for a wide range of infectious diseases. Bacteria can cause illnesses like tuberculosis and strep throat, while viruses are responsible for diseases like the flu and COVID-19. Fungi can lead to infections such as athlete's foot, and protozoa can cause diseases like malaria. Epidemiologists study these organisms to understand their life cycles, transmission patterns, and the factors that contribute to their spread.
