Moality rate of measles in developing countries?

Ans. is 'a' i.e., 10% Measles-associated moality is usually higher among the very young and very old. Moality in developing countries may be as high as 10 to 15% due to one or several factors, including the early age of infection, malnutrition, diarrhea, concomitant/secondary bacterial infections, and lack of access to good medical care. Most common cause of death is pneumonia in children and encephalitis in adults.
