What You Need To Know

  • Seven of the cases are Ohio residents

  • This year's cases have already surpassed last year's total measles cases in Ohio, which was 10

  • As of April 3, there have been more than 600 cases of measles confirmed in the United States

Knox Public Health said seven of the cases are Ohio residents, who are linked to the initial case of measles in Knox County in March. These individuals have been isolated and their symptoms are being monitored, Knox Public Health said in a release.

The confirmation comes just a little over a week after the county confirmed two more cases in the county. Knox County’s first case of measles was confirmed in late March, which was a visitor to the county who exposed others in the county, the health department said.

The cases are officially an outbreak in the county, as an outbreak is defined as three or more cases in an area, according to the Centers for Disease Control and Prevention. 

So far, this year’s total has surpassed last year’s total measles cases in Ohio, which was 10, according to the Ohio Department of Health. In addition to Knox County’s cases, 10 cases were confirmed in Ashtabula County in March

As of April 3, there have been more than 600 cases of measles confirmed in the United States reported by 22 states, according to the CDC: Alaska, California, Colorado, Florida, Georgia, Kansas, Kentucky, Maryland, Michigan, Minnesota, New Jersey, New Mexico, New York City, New York State, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Vermont and Washington.

Officials across the U.S. have been urging families to vaccinate children, as the disease can spread quickly. CDC data also shows that vaccination rates for the measles, mumps and rubella vaccine in Ohio are below the benchmark of the recommended 95% by health officials, as they say 95% vaccination rates in a community can help develop herd immunity to a disease.

Over the last five years, vaccination among kindergarteners in Ohio has wavered around 89%. According to the CDC, the Buckeye State is also among states with the lowest vaccination rates. 

Measles is highly contagious and can spread easily when a person breathes, coughs or sneezes. Each case can lead to an additional 12 to 18 cases if people aren’t protected against the disease, according to the Ohio Department of Health.

Signs and symptoms include:

  • Running nose
  • Cough
  • Red and watery eyes
  • Small white spots inside the cheeks

Death is usually caused by complications from the disease, including:

  • Blindness
  • Encephalitis (an infection causing brain swelling and potentially brain damage)
  • Severe diarrhea and related dehydration
  • Ear infections
  • Severe breathing problems, including pneumonia
