Which of the following is an example of a non-communicable disease?

• A. Asthma
• B. Influenza
• C. Cholera
• D. Tuberculosis

Answer: (A)

Non-communicable diseases are conditions that cannot be spread from one person to another. They’re typically chronic and tend to involve long-term management, often influenced by genetics, lifestyle, or environmental factors. Asthma fits this idea because it’s a long-lasting inflammatory condition of the airways that you don’t catch from someone else. It requires ongoing treatment and trigger management, but it isn’t contagious.

The other options are infectious diseases caused by germs that can spread between people or through contaminated sources. Influenza is a viral illness that spreads through respiratory droplets. Cholera comes from a bacterium in contaminated water and can spread through drinking or using affected water. Tuberculosis is another bacterial infection that mainly spreads through the air when an infected person coughs or sneezes. Because these can be transmitted from person to person, they’re not non-communicable.

So asthma is the non-communicable example.
