(CNN Newsource) - According to the Centers for Disease Control and Prevention (CDC), the total number of measles cases has now jumped to 704 in the United States, and that number is expected to rise.
Seventy-one percent of those cases involve unvaccinated people.
The rise in cases is forcing the CDC to issue vaccine guidelines for babies who may be traveling internationally.
Because of the fast spread of the highly contagious virus, the CDC says babies between the ages of 6 and 11 months should get the vaccine before they travel internationally.
The CDC normally recommends parents wait until about 12 months to get their babies vaccinated, but these changes come as global concerns for measles are surging.
Doctors recommend two doses of the MMR vaccine, which covers measles, mumps and rubella.
Doctors typically give the first dose between 12 and 15 months, and the second between 4 to 6 years.
The CDC says if you were vaccinated with two doses, you have a 97% chance at preventing the measles.
Currently, the number of measles cases is the highest since 2000, which is when the disease was eradicated in the U.S.
This update comes on the same day the CDC is kicking off its 2019 National Infant Immunization Week.
