The U.S. logged fewer than 30 measles cases this week as Ohio health officials confirmed three outbreaks in two counties were over.

There have been 1,197 confirmed measles cases this year, the Centers for Disease Control and Prevention said Friday. Health officials in Texas, where the nation’s biggest outbreak raged during the late winter and spring, confirmed two cases in the last week.

There are three other major outbreaks in North America. The longest, in Ontario, Canada, has resulted in 2,083 cases from mid-October through June 10. The province logged its first death June 5 in a baby who got congenital measles but also had other preexisting conditions.

Other U.S. states with active outbreaks — which the CDC defines as three or more related cases — include Arizona, Colorado, Illinois, Kansas, Montana, New Mexico, North Dakota and Oklahoma.

Earlier outbreaks in Indiana, Michigan, Ohio and Pennsylvania were declared over by health officials after six weeks of no new cases.

In the U.S., two elementary school-aged children in the epicenter in West Texas and an adult in New Mexico have died of measles this year. All were unvaccinated.

Measles is caused by a highly contagious virus that’s airborne and spreads easily when an infected person breathes, sneezes or coughs.

It is preventable through vaccines, and has been considered eliminated from the U.S. since 2000.
