ANN ARBOR, Mich. (WILX) -- The first reported measles case in Washtenaw County wasn't measles.
According health officials speaking to the The Ann Arbor News and MLive, a child exhibiting symptoms of measles initially tested positive for the contagious disease. But additional testing showed it was not measles.
A spokesperson for the Washtenaw County Health Department says the child's symptoms were caused by a reaction to a vaccine.
Health officials alerted the public Monday, April 8 to what was initially believed to be a confirmed case of the measles.
They're also urging people again to get vaccinated if they haven't received the vaccine in the past. Measles is highly contagious and is spread by personal contact and through the air.
The state considers the vaccine to be highly effective and safe. A single dose protects about 95% of children. After two doses, almost 100% are immune.
