An additional 90 measles cases were reported across the nation last week, the biggest jump this year as the annual total continued its march toward record levels.

According to USA Today, the Centers for Disease Control and Prevention said 555 cases have been confirmed in 20 states in 2019, the second highest total in almost two decades.

The numbers are up sharply from a week ago, when the total number of cases stood at 465 in 19 states.

Globally, the World Health Organization reported Monday that cases rose by 300 percent in the first three months of this year.

The U.S. surge has been fueled in part by the anti-vaccination movement, the majority of people who contract measles have not been vaccinated, the CDC said.
