my son is 17 months old. he had fever which started last Wednesday for 3 days. after that fever was gone but he got some red rashes in his body. but he's active and not feeling bothered about those rashes. it's been one week since he started getting rashes. it's not spreading sometimes we can see but sometimes it's not. is it measles. he got his MR vaccine when he was 10 months couldn't take the second dose
