A recent measles outbreak traced to Disney theme parks in California includes five park employees who were infected, officials said Tuesday.
Of the five employees at Disneyland and Disney California Adventure in Anaheim, three have fully recovered and returned to work, and two remain off, said Dr. Pamela Hymel, the chief medical officer for Walt Disney Parks and Resorts.

All of Disney's "cast members," as it calls park employees, have been offered immunity tests and vaccinations since the company first heard of the outbreak Jan. 7, Hymel said. Those who have been in close contact with infected employees are put on paid leave until their immunity can be established.
Several dozen measles cases have emerged in California, four other states and Mexico in the outbreak linked to December visits to Disney theme parks in Orange County.
