Maryland Confirms First Measles Case in International Traveler

The state of Maryland has confirmed its first measles case involving a resident from Howard County who recently traveled abroad. This alarming development raises concerns about the spread of the highly contagious virus.

The Maryland Department of Health announced the case in a news release on Sunday, with confirmations also coming from the Virginia Department of Health and local health officials in Howard County. While measles outbreaks have recently been reported in other states, the health department clarified that this case does not link to any outbreaks in Texas or New Mexico.

Details of the Case

Health officials are working diligently to determine individuals who may have been exposed to the virus during the travel period. Officials have identified specific times and locations where potential exposure could have occurred.

Exposure Locations

March 5, 4 p.m. to 9 p.m.: Washington Dulles International Airport, Terminal A, including transportation to the main terminal and the baggage claim area.

March 7, 3:30 p.m. to 7:30 p.m.: Johns Hopkins Howard County Medical Center Pediatric Emergency Department.

Symptoms and Precautions

The Maryland Department of Health has urged residents to remain vigilant and monitor any symptoms that may arise after potential exposure. Early signs of measles typically include:

Fever exceeding 101 degrees Fahrenheit
Runny nose
Cough
Red, watery eyes

A distinctive red rash is usually the next symptom, appearing on the face and then possibly spreading throughout the body. This rash generally develops one to four days following the initial symptoms.

Symptoms of measles can emerge seven to 21 days after exposure, although they most frequently appear within a 10 to 14 day window, according to health officials.

Contagious Nature of Measles

The contagious period for a person infected with measles begins four days before the rash’s appearance and lasts until four days after. Dr. Marc Siegel, a senior medical analyst, emphasized the virus’s high contagion rate, noting that the risk of infection for unvaccinated individuals entering a room shortly after someone with measles can be as high as 90%.

Vaccination and Prevention

The Centers for Disease Control and Prevention and various healthcare experts strongly recommend the measles, mumps, and rubella (MMR) vaccine as the most effective way to prevent measles. The Maryland Department of Health cautions that certain groups are at greater risk for severe complications from measles, including:

Pregnant women
Infants younger than one year
Individuals with weakened immune systems

Monitoring for Symptoms

Health authorities advise individuals who may have been exposed during the indicated times to closely monitor for any early symptoms of measles for up to 21 days post-exposure. Those experiencing symptoms such as a fever should avoid public places, including schools and workplaces, and contact their healthcare provider promptly. Consultation via phone before visiting a healthcare facility is crucial to prevent potential virus transmission to other patients.

Recent Trends in Measles Cases

The occurrence of measles cases in Maryland remains relatively sporadic, with reports indicating one case in 2024, another in 2023, and no reported cases between 2020 and 2022. In stark contrast, Texas has confirmed nearly 200 measles cases as of last week, predominantly impacting unvaccinated children of school age.

Stay Informed and Safe

The recent confirmation of the measles case in Maryland serves as a reminder of the importance of vaccination and awareness of health risks associated with travel. Individuals should remain informed about potential outbreaks and ensure that their vaccinations are current. By taking proactive steps, communities can work towards preventing further cases and safeguarding public health.
