Two measles cases were confirmed in Ashtabula County, and health officials said anyone at three listed Ohio locations could have been exposed while the infected people were contagious.
July 17-18 exposure sites include Sugarcreek Stockyard, Bloomfield Livestock Auction and Hillcrest Hospital’s adult emergency department, with risk extending through the visit and 2 hours afterward.
July 24 to Aug. 19 is the likely symptom window for people who are not immune, while those with weakened immune systems may take longer to show signs.
9 out of 10 unprotected people exposed to measles can become ill, the Ohio Department of Health said, while two MMR doses are 97% effective and officials are promoting vaccination.
