- Safety and Health Topics
Measles is a highly contagious illness that primarily spreads via:
- Droplets or airborne particles from the noses, mouths, or throats of infected people.
- Contact with an infected person’s respiratory secretions or saliva.
- Contact with surfaces contaminated with respiratory secretions or saliva.
Despite a great reduction in the number of cases and near eradication of the disease in the United States at the start of the 21st century, measles continues to occur domestically. Measles is usually a childhood disease but can affect individuals of any age. Outbreaks are most common in the winter and spring.
Initial symptoms, which usually appear 10–12 days after infection, include high fever, runny nose, red eyes, and white spots on the inside of the mouth. Several days later, a rash develops, starting on the face and upper neck and gradually spreading to the rest of the body. Measles is typically most contagious several days before the rash appears. In some cases, measles can lead to severe complications, including fatal pneumonia.
Workers may be exposed to measles whenever the virus is circulating in the community. Some workers also may be exposed to infected individuals who arrive in the U.S. from abroad. Workers who perform services or other activities in homes in affected communities also may be exposed. Workers who have not received the measles vaccine or who have not had the disease can get measles if they are exposed.
The measles, mumps, and rubella (MMR) vaccine can prevent measles. For the vast majority of recipients, the vaccine is safe and effective. As with almost any vaccine, however, a small number of recipients may experience allergic reactions, side effects, or other adverse events. The benefits of vaccination typically far outweigh these risks.
This page provides information about measles for workers and employers. It addresses developing infection control plans and other infection prevention measures for workers in general and for those who may be at higher risk, including:
- Healthcare and dental workers.
- Childcare and school workers.
- Laboratory workers.
- Environmental services workers.
- Workers who are pregnant.
- Workers who travel abroad.
This page includes the following sections:
Provides an overview of the history of measles.
Provides information on measles that may aid in recognizing and assessing the risk of infection, particularly through exposure to infected individuals.
Provides information about vaccination and post-exposure treatment. This page also highlights signs and symptoms of measles, disease progression, and diagnosis.
Provides information about OSHA standards, letters of interpretation, directives (instructions for compliance officers), and other requirements that may apply in the event of possible worker exposure to measles.
Control and Prevention
Provides general guidance for workers and employers of workers who may be exposed to measles. This page also offers specific guidance for protecting workers who may be at increased exposure risk.
Provides links to additional resources and information for protecting workers from occupational exposure to measles.
Workers have the right to:
- Working conditions that do not pose a risk of serious harm.
- Receive information and training (in a language and vocabulary the worker understands) about workplace hazards, methods to prevent them, and the OSHA standards that apply to their workplace.
- Review records of work-related injuries and illnesses.
- File a complaint asking OSHA to inspect their workplace if they believe there is a serious hazard or that their employer is not following OSHA's rules. OSHA will keep all identities confidential.
- Exercise their rights under the law without retaliation, including reporting an injury or raising health and safety concerns with their employer or OSHA. If a worker has been retaliated against for using their rights, they must file a complaint with OSHA as soon as possible, but no later than 30 days.
For additional information, see OSHA's Workers page.
How to Contact OSHA
Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA's role is to ensure these conditions for America's working men and women by setting and enforcing standards, and providing training, education and assistance. For more information, visit www.osha.gov or call OSHA at 1-800-321-OSHA (6742), TTY 1-877-889-5627.
