Maryland health officials have confirmed five cases of measles among state residents following recent travel outside the state. The Maryland Department of Health said the infections are linked to travel and has issued a public advisory for people who may have been exposed.
According to the department, anyone who visited the Carroll Hospital Center Emergency Department waiting room between 2 p.m. and 5 p.m. on July 13 may have been exposed to the virus. Health officials are asking anyone who was at the location during that time to review their vaccination status and monitor for symptoms.
The department said people who believe they were exposed should first confirm whether they have been fully vaccinated against measles. Vaccination records are available through healthcare providers or local health departments.
Officials said people who have received two doses of a measles-containing vaccine, such as the MMR vaccine, or those born before 1957 are generally considered protected and do not need to take additional action. Individuals who have received only one dose are likely to have protection but are encouraged to speak with their healthcare provider about receiving a second dose for full immunity.
People who are not fully vaccinated should closely monitor their health for 21 days after the possible exposure. Anyone who develops symptoms should immediately isolate and contact a healthcare provider or local health department for guidance.
Health officials also advised immunocompromised individuals who may have been exposed to contact their doctor, especially if symptoms begin to appear.
Measles symptoms usually develop in two stages. The first stage typically begins seven to 14 days after exposure. Early signs include a fever higher than 101 degrees Fahrenheit, a runny nose, red or watery eyes, and a cough.
Three to five days after the first symptoms begin, a red rash usually appears on the face before spreading to the rest of the body. A person with measles can spread the virus from four days before the rash appears until four days after it develops, making the disease highly contagious.
Health experts say measles spreads through the air when an infected person coughs, sneezes, or breathes. The virus can remain in the air and infect people who have not been vaccinated. According to the US Centers for Disease Control and Prevention, about nine out of ten unvaccinated people exposed to measles will become infected.
Although measles can lead to serious complications, including hospitalization, it can be prevented through vaccination. The MMR vaccine provides strong protection against measles, mumps, and rubella and remains the most effective way to reduce the risk of infection.
The Maryland Department of Health is encouraging everyone who is eligible to ensure they are fully vaccinated. Officials noted that the MMR vaccine is covered by most health insurance plans. It is also available at no cost for eligible residents through the Maryland Vaccine Program and the Vaccines for Children Program for those without insurance.
Health authorities continue to monitor the situation while reminding residents to stay alert for symptoms and seek medical advice if they believe they have been exposed. Officials said early identification, isolation, and vaccination remain the most effective tools for preventing the spread of measles within the community.
