Measles reported in a Montgomery County resident

February 5, 2024- A case of measles was identified in a Montgomery County resident evaluated at Dayton Children’s Hospital in the main campus Emergency Department at One Children’s Plaza in Dayton on January 29, 2024, and January 31, 2024.  Individuals in the emergency department may have been exposed to measles between January 29th at 11 pm and January 30th at 7 am and on January 31st between 10:30 am and 6 pm.

Contacts of the person with measles are being notified by Public Health to assess their measles vaccination status and to provide information regarding signs and symptoms of measles, and appropriate quarantine measures. Mercer County Health District (MCHD) was made aware of the contacts who live in Mercer County. All Mercer County residents exposed to the patient were immunized with the measles vaccine before exposure.

MCHD Measles Fact Sheet

Contacts who are not fully vaccinated for measles should be immunized with measles vaccine as soon as possible after exposure. A measles vaccine given within 72 hours after exposure may prevent or reduce the severity of the disease. Measles immune globulin (IG) can prevent or modify measles in a susceptible person if given within six days of exposure. IG may be especially indicated for susceptible household contacts <1 year of age, pregnant women, or immunocompromised persons, for whom the risk of complications is increased. The measles vaccine is highly protective; one dose of the measles-mumps-rubella (MMR) vaccine provides 93% protection against measles and two doses provide 97% protection. MMR vaccine can also be given to adults born after 1957 who are not vaccinated, or whose vaccination status is unknown.

Measles is very contagious.  Children infected with measles can spread it to others, even before they have symptoms.  The measles virus can live for up to two hours in the air after an infected person leaves the room. Nine out of 10 unvaccinated children who are exposed to measles will become infected.  Symptoms may not occur for up to 21 days after exposure to an individual who has measles.

Symptoms of measles can include high fever, cough, runny nose, watery eyes, and a rash beginning 3-5 days after other symptoms occur.  Measles can be serious, and about 1 in 5 children who get measles will be hospitalized with complications such as pneumonia, dehydration, or brain swelling. 

Ohio had one measles case in 2023, and 90 in 2022, when an outbreak centered in central Ohio totaled 85 cases. Those cases were the first in the state since 2019. Measles prevalence has been increasing recently internationally and there have been recent reported cases in the United States, as well.
