Since Feb. 1, new measles cases have been reported in two new states — Ohio and Maryland.
The case in Ohio was evaluated and confirmed at Dayton Children's Hospital, according to Montgomery County health officials. It's the county's first reported case since 2005.
The Maryland resident with a confirmed case had recently traveled internationally and acquired the infection abroad, according to the news release.
Neither confirmed case is connected to the recent outbreak of nine measles cases in and around the Philadelphia area.
"Measles is ten times more infectious than COVID. If you're exposed, there's a good chance you're going to get it if you're not vaccinated," Scott Krugman, MD, a pediatrician at Sinai Hospital in Baltimore told CBS News.
Aside from the outbreak in Pennsylvania and these two most recent cases in Ohio and Maryland, exposure warnings and cases have also appeared in Missouri, Colorado, and Georgia in recent months.
