Infectious diseases are illnesses caused by microorganisms, such as bacteria, viruses, fungi, or parasites, that invade the body and cause damage. Some infections are mild and resolve on their own, while others can become life-threatening without proper treatment. Understanding infectious diseases — how they spread, how they’re treated, and how to prevent them — is vital for protecting your health and your community.
What Causes Infectious Diseases?
The main culprits behind infectious diseases are:
-
Bacteria – Single-celled organisms (e.g., tuberculosis, urinary tract infections)
-
Viruses – Tiny organisms that replicate inside host cells (e.g., flu, HIV, COVID-19)
-
Fungi – Can infect the skin, nails, lungs (e.g., athlete’s foot, thrush)
-
Parasites – Organisms like worms or protozoa (e.g., malaria, giardiasis)
These pathogens can enter your body through contaminated food, water, air, insect bites, or close contact with an infected person.
