There is currently an outbreak of measles in mostly unvaccinated individuals in several states in the United States (including a large outbreak in western Texas and surrounding states). As of April 19, 2025, Virginia also has its first reported case of measles, in a 3 year old, details here (The Virginia Register) : "A child is the state's first confirmed case of measles among Virginia residents, the Virginia Department of Health said Saturday. While the agency did not release specifics about the child's identity or where they live, it did say the child was under four years old and lives in the northwest portion of Virginia. It also said VDH was coordinating efforts to identify anyone who could have been exposed by the child and their family. The child had recently travelled internationally, VDH said. Specifically, the agency is looking for anyone who may have been at the following locations earlier in the week: Kaiser Permanente Caton Hill Medical Center, Advanced Urgent Care, located at 13285 Minnieville Road in Woodbridge on Tuesday, April 15 from 10 a.m. to 1:30 p.m.; or Kaiser Permanente Fredericksburg Medical Center, Pediatrics Department, located at 1201 Hospital Drive in Fredericksburg on Wednesday, April 16 from noon to 5 p.m. 'This first case of measles in Virginia this year is a reminder of how easily this highly contagious disease can spread, particularly with international travel,' VDH State Epidemiologist Dr. Laurie Forlano said in a statement. 'Vaccination remains our best defense against measles and is safe and highly effective at protecting people and preventing outbreaks. We urge Virginians, especially those planning to travel, to check their vaccination status, talk to their health care provider, and get the MMR vaccine if needed.' " The Centers for Disease Control (CDC) website is only being updated weekly at this point, so please check the Virginia Department of Health (VDH) for the most up-to-date information in our area , as well as national news or local health department websites for the latest information on case numbers for each state. The Healthy Children website has a comprehensive description of measles and the vaccine schedule for children here. Remember that the measles vaccine is extremely safe and protective. However, it is a live attenuated vaccine and so some who are immunocompromised or pregnant cannot get the shot (if they were not immunized previously). Also, the first dose is typically administered at 12 months of age, so most infants are at high risk for getting infected. Infants, other unvaccinated, and immunocompromised individuals all rely on herd immunity to keep them safe, so it is important to keep communities protected against measles to protect everyone. When herd immunity drops below 95%, outbreaks are likely to happen once someone with measles enters the community (often from international travel). Some measles facts: Measles is considered one of the most infectious diseases (airborne) on earth. If 10 unvaccinated people are exposed to someone with measles, 9 will get infected. It can also make children very sick - for people without immunity, 1 in 5 will be hospitalized, 1 in 20 will develop pneumonia (the most common way measles kills young children), 1 in 1000 will develop encephalitis (infection of the brain, sometimes causing permanent brain damage), and 1-3 in 1000 will die. It can cause “immune amnesia,” where the immune system loses its ability to fight other viruses that people were previously immune to. Children are normally vaccinated against measles with the Measles, Mumps, Rubella (MMR) vaccine at 12 months and again at 4-5 years of age, but can get an accelerated schedule in case of outbreaks. Accelerated schedule in case of community outbreaks: Extra dose for 6-11 month old infants , with second dose at 12+ months of age (28+ days after the first dose) For children who have only had the 12 month dose , they can get their second dose of vaccine 28+ days after the first dose. The vaccine is fully protective approximately 10-14 days after administration (93% protection after 1 dose, 97+% protection after the second dose.) People born before 1957 might not require vaccination because measles was so widespread in the mid-1950s and earlier, it is assumed that everyone already had the disease and has natural immunity. However, during an outbreak it might be worth checking immunity (IgG to measles) or getting an MMR booster, particularly if you are a healthcare worker. People born between 1957 and 1968 may have gotten only 1 dose of killed measles vaccine (less effective than the current vaccine) and should check immunity (IgG to measles) or get an MMR booster if they have not previously gotten a second shot. Because MMR is a live attenuated virus vaccine, those who are pregnant or significantly immunocompromised cannot get the vaccine. Find more measles information at HealthyChildren.org .
