• A. It only affects adults
• B. It usually results in a cough and cold symptoms
• C. It is a highly contagious disease that can lead to severe complications
• D. It has no vaccine available

Answer: (C)

A key characteristic of measles is that it is a highly contagious disease that can lead to severe complications. Measles is caused by a virus that is spread through respiratory droplets when an infected person coughs or sneezes. This high level of contagiousness means that people who are not immune can easily contract the virus, and outbreaks can occur in populations with lower vaccination rates.

Complications from measles can be serious and include pneumonia, encephalitis (inflammation of the brain), and can even be fatal in some cases. These potential health risks underscore the importance of vaccination, which is highly effective in preventing measles and its complications.

In contrast, other statements lack accuracy regarding the nature of the disease. Measles can affect individuals of all ages, not just adults. Although cough and cold symptoms can accompany measles, they are not the primary characteristics of the disease – the distinctive rash and fever are more indicative. Additionally, a vaccine for measles is readily available and is a critical part of childhood vaccination programs worldwide, significantly reducing the incidence of the disease.
