Officials in Rockland County, New York, declared Wednesday that its measles outbreak is over.

The first measles case in Rockland County was identified October 1, 2018, with the last rash onset from measles identified August 13, 2019.

Since the start of the outbreak, there were 312 confirmed cases of measles in Rockland County, according to the Rockland County Health Department.

No new cases of the virus have been reported in the affected area since August 13. A measles outbreak is officially declared over 42 days after the last person infected by the disease develops a rash.

More than 80% of the cases were in people age 19 and younger, Dr. Patricia Schnabel Ruppert, the Rockland County health commissioner, said at a news conference Wednesday. The county saw acute complications with multiple hospitalizations, including care for pneumonia and preterm births.
