Health officials said this week that an outbreak of measles tied to Disneyland and Disney California Adventure includes several employees, and they live in various counties.

The outbreak has affected several dozen people from five U.S. states and Mexico, according to the Associated Press.  

Measles is so contagious a person may contract it simply by being in a room where someone with the virus once was. It remains active on a surface for up to two hours.

It is generally passed along through sneezing and coughing and personal contact with infected bodily fluids.

Reports indicate that at least three of five infected workers (called “cast members”) have recovered and are back at work. All the park employees have been given immunity tests and offered vaccinations.

In 2014, the Centers for Disease Control and Prevention said the U.S. saw a record 644 cases of measles in 27 states.

“The majority of the people who got measles are unvaccinated,” the CDC’s website states.

The U.S. declared in 2000 the measles had been eliminated from the country, and that was the result of the highly effective vaccination program.

The measles is common in places such as Europe, Asia, the Pacific and Africa, according to the CDC. Typically it enters the U.S. via travelers who bring it, and it spreads among those who are unvaccinated.

Also in 2014, the Philippines experienced a large outbreak.
