A second case of measles in D.C. has been confirmed.

According to the D.C. Department of Health, the second confirmed case isn’t linked to the outbreak in California.

“As we continue to monitor this situation, residents are strongly encouraged to get vaccinated as soon as possible,” DOH Director, Dr. LaQuandra S. Nesbitt, said in a statement. “Adequate prevention and protection of measles requires we work together as a city to educate, inform and help ensure residents are equipped with the necessary tools and resources needed to reduce possible new cases of measles in the future. We are asking all healthcare providers to review their patients’ immunization history at every visit to ensure that everyone is protected.”

Though measles is more severe in infants than adults, it’s a highly contagious illness. Symptoms include fever, pink or red eyes, and a cough, followed by red blotchy rash on your skin, beginning on your face before spreading to the rest of your body.

Currently, Southern California is experiencing an outbreak of the illness, with 84 reported cases. DOH officials don’t believe that the two measles cases in D.C. are link to the outbreak. Measles can be prevented with a two dose vaccination, which you can request from your doctor.
