The Centers for Disease Control and Prevention reports that over 1,000 cases of measles have been confirmed in 28 states, including California. According to the Occupational Safety and Health Administration, the nature of the work done by health care workers puts them at significant risk of infection. Child care workers and those who work in laboratories are also at a high risk of exposure.
Health care workers are frequently exposed to airborne particles and droplets from throats, noses and mouths of people who are infected by measles. Any direct contact with saliva or respiratory secretions of infected individuals or even contaminated surfaces poses risks. Although measles is a known childhood disease, people of all ages can be infected.
