Montgomery County officials warned Friday that recent visitors to a Bethesda, Md., ice rink and a Gaithersburg office building may have been exposed to measles from a confirmed patient.
The confirmed case of measles is the first reported in Maryland since 2019, when the state had five confirmed cases.
The infected person visited the Cabin John rink in Bethesda on May 24 between 6 and 9 p.m., and also visited an office building at 16220 Frederick Road in Gaithersburg between 11 a.m. and 2 p.m. Tuesday.
Measles, which can be prevented by vaccination, is an airborne disease transmitted by coughing, sneezing and spitting up from infected people.
Measles symptoms develop between one and three weeks after a person’s first exposure. Early symptoms include fevers over 101 degrees Fahrenheit, a runny nose, cough, and red, watery eyes.
After one to four days, a red rash appears, first on the face and then on the rest of the body. People with measles are contagious for four days before the rash appears and then for four days after it appears.
Health officials are urging all unvaccinated against measles who were in either of the two locations exposed to the disease to monitor for symptoms and contact a health care provider if they start, especially fever.
