- Breathing in the virus after an infected person coughs or
sneezes near you

People who are infected but not having symptoms are also able to transmit the virus.
How long can an infected person spread this virus?
An infected person can spread the illness starting from three days before until up to nine days after symptoms begin.
Where does mumps occur?

How is mumps diagnosed?

Should people with mumps be excluded from work or school?
People with mumps should be excluded from:
- Child care facilities
- Sensitive occupations
- Public gatherings
- Contact with any non-vaccinated person
The exclusion should last for at least five days after the onset of swelling of the lymph nodes or salivary glands.
What are the complications from mumps?
Complications can include:
- Meningitis (inflammation of the covering of the brain and spinal column)
- Swelling of the testicles or ovaries
- Inflammation of the pancreas
How can mumps be prevented?
Receiving the mumps vaccine (MMR) is the primary method of prevention of mumps infections.
Two doses are required to consider a person immune. Two MMR vaccinations provide immunity 95 percent of the time. This means that 5 percent of people are not immune and can be infected by the mumps virus despite being vaccinated twice. Individuals without a documented natural infection or record of two vaccinations with MMR should be vaccinated to prevent infection with the mumps virus.
The MMR vaccine is available at Southern Nevada Health District locations throughout the valley. Visit the Immunization Clinic webpage or call 759-0850 for vaccine information.
