Over the past several weeks there have been three measles cases confirmed in people living in or traveling through the National Capitol Region. And sadly we are not alone, measles outbreaks are occurring in every region of the world with health officials in many countries reporting large outbreaks. Measles is caused by a highly contagious virus. In fact, it is so contagious that if one person has it, up to 90% of the people close to that person who are not immune will also become infected. Measles spreads through the air when an infected person coughs or sneezes. Other people then become infected when they breathe contaminated air or touch an infected surface and then touch their eyes, nose, or mouth. The measles virus can live for up to two hours in an airspace after an infected person leaves the area. Measles symptoms typically begin with a high fever, cough, runny nose, and watery eyes followed by a rash. Measles can be serious in all age groups. However, some groups are more likely to suffer from complications: Children younger than five years of age Adults older than 20 years of age Pregnant people People with compromised immune systems, such as from leukemia or HIV infection Serious complications include pneumonia (infection of the lungs) and encephalitis (infection of the brain). Measles infection can also be fatal. Measles and Travel Measles is still common in many places, including Europe, the Middle East, Asia, and Africa. Every year, measles is brought into the United States by unvaccinated travelers, most often Americans and sometimes foreign visitors, who get measles while they are in other countries. Credit: CDC If you plan to travel internationally, make sure you and your family are protected, no matter where you are going. The best protection against measles is vaccination. You should plan to be fully vaccinated at least 2 weeks before you leave for your trip. Measles Prevention Vaccines help teach the immune system how to defend against germs, helping to build up natural defenses. They can prevent common diseases that used to seriously harm or even kill infants, children, and adults — like measles. The MMR vaccine protects against three diseases: measles, mumps, and rubella. It is safe and highly effective: two doses are about 97% effective at preventing measles if exposed to the virus. See the recommend vaccine schedule to learn more about when your child should get an MMR vaccine, and other recommended vaccines. Following the recommended schedule helps reduce the risk of serious diseases that can be prevented. While under the routine immunization schedule, children receive their first vaccine against measles at 12-15 months of age, infants between 6 and 11 months of age should receive one dose of measles vaccine before traveling internationally.

COVID-19 Vaccination Dashboard Revised
February 9, 2024
The COVID-19 Vaccination Dashboard has been updated with a new focus on 2023-2024 COVID-19 vaccine data. The CDC currently recommends a single 2023–2024 updated COVID-19 vaccine for most people.* Therefore the Fairfax County Health Department will no longer report data on the percentage of residents in Fairfax Health District who completed their primary series and boosters. Instead, the dashboard now focuses on 2023-2024 COVID-19 vaccine metrics and the total doses given since COVID-19 vaccines became available. The updated COVID-19 vaccines have been recommended since September 2023. They were updated to provide more protection from severe disease, hospitalization, and death from the variants that are currently circulating. Currently, 18.6% of residents in Fairfax Health District received the 2023-2024 COVID-19 vaccine. We continue to encourage you to keep yourself and others in the community safe by staying up to date with the recommended vaccines. Vaccination remains the safest way to avoid hospitalization, long-term health outcomes, and death. Learn more about the benefits. It’s not too late to get a COVID-19 vaccine. Visit to find a location near you. If you are uninsured or underinsured, you can get a no-cost COVID-19 vaccine through participating providers. Visit the CDC’s Bridge Access Program page for more information.   * Vaccine recommendations are based on age, and in some cases, time since last dose, the first vaccine received, and immunocompromised status. People who are immunocompromised or younger than 5 years may need an additional dose.

Virginia Department of Health is Working to Identify People Who Are at Risk From the Virginia Department of Health The Virginia Department of Health (VDH) was notified of a confirmed case of measles in a person who traveled through Northern Virginia when returning from international travel. Out of an abundance of caution, VDH is informing people who were at various locations, including Dulles International Airport on January 3, 2024, and Ronald Reagan Washington National Airport on January 4, 2024, that they may have been exposed. Health officials are coordinating an effort to identify people who might have been exposed, including contacting potentially exposed passengers on specific flights. Listed below are the dates, times, and locations of the potential exposure sites associated with this case of measles: Location Date and Time Dulles International Airport (IAD) International arrivals area of the main terminal Between 4 p.m.-8 p.m. on Wednesday, Jan. 3, 2024 Ronald Reagan Washington National Airport (DCA) Terminal A Between 2:30 p.m.-6:30 p.m. on Thursday, Jan. 4, 2024   Measles is a highly contagious illness that can spread easily through the air when an infected person breathes, coughs, or sneezes. Measles symptoms usually appear in two stages. In the first stage, most people have a fever of greater than 101 degrees, runny nose, watery red eyes, and a cough. These symptoms usually start 7 to 14 days after being exposed. The second stage starts 3 to 5 days after symptoms start, when a rash begins to appear on the face and spread to the rest of the body. People with measles are contagious from 4 days before the rash appears through 4 days after the rash appeared. What should you do if you were at one of the above locations on the day and time specified? If you have never received a measles containing vaccine (either the measles, mumps and rubella [MMR] vaccine or a measles only vaccine which is available in other countries), you may be at risk of developing measles. Anyone who was exposed and is at risk of developing measles should watch for symptoms until January 25, 2024. If you notice the symptoms of measles, immediately isolate yourself by staying home and away from others. Contact your healthcare provider right away. Call ahead before going to your healthcare provider’s office or the emergency room to notify them that you may have been exposed to measles and ask them to call the health department. This will help protect other patients and staff. If you have received two doses of a measles containing vaccine, or were born before 1957, you are protected and do not need to take any action. If you have an immunocompromising condition, please consult with your healthcare provider if you have questions or develop symptoms. If you have received only one dose of a measles containing vaccine, you are very likely to be protected and your risk of being infected with measles from any of these exposures is very low. However, to achieve complete immunity, contact your healthcare provider about getting a second vaccine dose. Measles is preventable through a safe and effective MMR vaccine. Two doses of the vaccine are given to provide lifetime protection. Virginia has high measles vaccination rates, with approximately 95% of kindergarteners fully vaccinated against measles. However, infants younger than 12 months of age are too young to be vaccinated. These infants, and others who are not vaccinated, are very susceptible to infection if they are exposed to someone with measles. If you or your child have not yet been vaccinated, call your health provider. To check your immunization status, call your healthcare provider or request records from the VDH Immunization Record Request Form. For additional information, contact your local health department. Healthcare providers should maintain an increased index of suspicion for measles in clinically compatible cases at all times, especially if patients were recently exposed. Measles is an immediately reportable disease. Contact the local health department right away to report any suspected cases and arrange for public health testing. For additional guidance on testing and infection control measures for healthcare providers, visit Residents with additional questions about their potential exposure can call VDH at (804) 864-8140 or email  For more information on measles, see the VDH Measles Fact Sheet.
