COLUMBUS, Ohio (WCMH) — Measles cases in Columbus continued to rise Wednesday as the total confirmed cases nears 50.

Columbus Public Health said there are now 46 measles cases in the area, a two case increase from Tuesday morning. The cases have been found in 18 daycare and school locations in the area, and increase of one from Tuesday.

Wednesday at 12:30 p.m., Columbus Public Health commissioner Dr. Mysheika Roberts and other city health officials provided an update on the outbreak.

19 people have been hospitalized with measles, an additional two from Tuesday. All of the 46 cases are in unvaccinated people under 16 years old, according to Roberts. 54% of the cases are in kids between the ages of 1 and 2.

Dr. Roberts added cases are spread between Columbus, Franklin County, and Ross County. She also announced that three public locations in town were exposed to measles. Those locations and dates and times of exposure are:

“I don’t want anyone to think if they were at that location during those times and they are unvaccinated, they should run to their provider to get tested,” said Roberts.

“If you develop symptoms, you need to be mindful of sharing with your health care provider that you could have been exposed to measles because you were in one of the locations and you should get tested. The testing cannot be done on someone who is asymptomatic. The worried well should not be going and calling their providers to get tested.”

Measles is a highly contagious virus transmitted through coughing and sneezing. According to the CDC, infected individuals can spread the virus for up to four days before becoming symptomatic.

It typically takes 8 to 12 days after exposure for symptoms to develop, according to both public health agencies.

The CDC recommends all children receive two doses of the MMR vaccine, with the first between 12 and 15 months old and the second at 4 through 6 years of age or at least 28 days after the first dose.
