What is measles?
Measles is a very contagious virus that spreads easily from person to person via the air or contact surfaces. The virus is released when an infected person breathes or coughs. Learn more about measles from the Virginia Department of Health.
Symptoms of measles normally appear 7-14 days after contact with the virus but can appear up to 21 days after. Common symptoms include:
- high fever
- rash
- cough
- runny nose
- red, watery eyes
The Measles, Mumps, and Rubella (MMR) vaccine is safe, effective, and provides the best protection against measles illness.
You can visit the Virginia Department of Health website for information on measles and about public exposure locations in Virginia related to confirmed cases of measles.
How do I know if I received the MMR vaccine?
Students can log into the Patient Portal and go to Immunizations in the navigation bar to check their immunization status. You can view submitted vaccines or titer lab test results indicating immunity to measles (Rubeola).
This information is submitted as part of the immunization compliance process as a new student.
How do I know if I am up-to-date on my MMR vaccine?
Two doses of MMR provide the best protection. Students can check their vaccination status in the Patient Portal.
If you are not sure about your status, talk to your healthcare provider. They can discuss options that may include a titer lab test to check your immunity or receiving vaccination. Students can call Student Health Services (703-993-2831) with questions or to schedule immunizations.
Individuals who are up-to-date with their vaccinations and/or got childhood vaccines are considered low risk. Infants (younger than 12 months who are too young to be vaccinated yet) and those who are not vaccinated are at-risk for infection if they are exposed to someone with measles.
