Amongst the respiratory tract infection, measles is related to malnutrition. It is related to malnutrition in both ways, i.e. - Measles tends to be more severe in the malnourished child. In a healthy child, measles precipitates malnutrition. That means measles predisposes malnutrition and vice versa. All cases of severe measles and all cases of measles in areas with high case-fatality rates should be treated with vitamin A, as many children develop an acute deficiency of vitamin A, which may lead to keratomalacia and blindness from corneal scarring. So, vitamin 'A' should be administered along with the measles vaccine. A high dose of vitamin A is given immediately on diagnosis of measles and repeated the next day. The recommended age-specific daily doses are 50,000 IU for infants aged < 6 months, 100,000 IU for infants aged 6-11 months, and 200,000 IU for children aged 12 months. If the child has clinical signs of vitamin A deficiency (Such as Bitot's spots) a third dose should be given 4-6 weeks later.
