National Measles Outbreak Concerns

Recent Measles Activity in the DMV Region
Prior Cases in Maryland and Vaccination Rates
The health alert in D.C. follows closely on the heels of Maryland health officials confirming three measles cases in residents who had traveled internationally and transited through Washington Dulles International Airport. Authorities have stated that those cases were not related to the outbreaks occurring in Texas, New Mexico, and Oklahoma. Details regarding the current D.C. case remain under investigation, and it is not yet known if it is connected to international travel.
DMV Vaccination Coverage
Washington D.C. currently has the lowest vaccination coverage in the DMV (District of Columbia, Maryland, Virginia) area, with approximately 92 percent of kindergarteners vaccinated. This rate is below the critical 95 percent threshold necessary to prevent community spread of measles. In comparison, Virginia reports a 94 percent vaccination rate, and Maryland boasts 97 percent, according to a 2024 Education Week report.
Importance of Measles Vaccination
High Contagiousness and Vaccine Effectiveness
Elevated vaccination coverage is crucial in preventing measles outbreaks due to the virus’s highly contagious nature. It is estimated that approximately nine out of ten unvaccinated individuals will contract measles if exposed. Measles is recognized as one of the most infectious diseases known. In response to recent measles activity in the DMV region, One Medical, a health provider managed by Amazon, is offering vaccination appointments to individuals lacking immunity.
Boosters are advised for individuals vaccinated before 1968, as they may have received less potent versions of the vaccine.
Measles Case Statistics and Severity
Current Year Case Numbers and Fatalities
To date, there have been 378 reported measles cases across 17 states this year, exceeding the 285 cases documented throughout the entirety of last year. Tragically, there has been one confirmed fatality—a six-year-old girl in Texas—marking the first measles-related death since 2015. Another death in New Mexico is currently under investigation.
MMR Vaccine Efficacy
The MMR vaccine is highly effective, with an estimated efficacy of 97 percent against measles. However, without vaccination, measles carries a significant risk, causing death in approximately one out of every 1,000 infected individuals due to severe complications such as pneumonia or encephalitis (brain swelling).
