(NBC NEWS) – A new study might pinpoint where the measles outbreak will spread next.
Researchers from Johns Hopkins say they designed a computer model that was able to predict the 25 counties at greatest risk for an outbreak.
The scientists looked at international air travel volume, population data, vaccination rates for children, and reported cases.
Most of the counties that have already confirmed cases are among those listed, including Denver County.
According to the CDC there are at least 764 confirmed cases in the country, which is the highest number in 25 years.
