A disease that is communicable is known as what?

• A. Infectious Disease
• B. Noncommunicable Disease
• C. Genetic Disease
• D. Degenerative Disease

Answer: (A)

A disease that can be passed from one person to another is called an infectious disease. These illnesses come from pathogens such as viruses, bacteria, fungi, or parasites, and they spread through methods like coughing or sneezing, direct contact, contaminated surfaces, or vectors like mosquitoes. Because they can move between hosts, they’re infectious.

This is different from noncommunicable diseases, which aren’t spread between people and include conditions like diabetes or heart disease. Genetic diseases are caused by inherited gene mutations, such as cystic fibrosis. Degenerative diseases involve gradual loss of function in tissues or organs, like osteoarthritis or Alzheimer's disease. So, when a disease is able to be transmitted between people, it’s described as infectious.
