What percentage of measles patients experience complications?

• A. 30%
• B. 10%
• C. 50%
• D. 5%

Answer: (A)

Measles tends to cause more problems beyond the fever and rash than many other viral illnesses. In typical pediatric cohorts, about a third of cases develop at least one complication, such as an ear infection, pneumonia, diarrhea, or dehydration, with more serious issues like pneumonia or encephalitis occurring less frequently but still contributing to morbidity. This overall complication rate, around 30%, is why that option is the best choice. The other figures would understate or overstate the true burden across common populations; vaccination, nutrition, and age can shift the risk, but the general estimate remains near 30% in unvaccinated or under-vaccinated groups.
