According to health officials, a patient contracted the measles virus during a trip overseas and was not diagnosed until after returning home and being admitted to the Children’s National Medical Center in Washington.
The patient was admitted on May 13, but was not diagnosed until six days later, while being in isolation. Between May 8 and the initial admittance date, the patient visited several places in Prince George’s County.
While most people choose to get vaccinated for measles and those that do not are at a potential risk if they are exposed. Health officials from the health departments in Washington and Prince George’s County, along with the Maryland Department of Health and Mental Hygiene said they wanted to spread the word “out of an abundance of caution.”
The measles virus is transmitted by large respiratory droplets through droplet contact and aerosolized droplet nuclei through the airborne transmission. People who have not received the vaccine, including pregnant women and those trying to become pregnant are at a high risk. Those women are not administered MMR vaccines, because of the theoretical risk to the developing fetus from vaccinating the mother with live vaccines.
In most parts of the world, measles is a common disease, but in the United States most of the cases stem from people, who contract the disease while traveling internationally.
