(CNN)The Washington State Department of Health reported Thursday what it said was the first confirmed measles death in the United States since 2003.

Authorities did not identify the woman, but said she was likely exposed to measles at a local health facility during a recent outbreak in Clallam County.
She died in the spring. The measles infection was discovered during an autopsy.
    "The woman had several other health conditions and was on medications that contributed to a suppressed immune system. She didn't have some of the common symptoms of measles such as a rash, so the infection wasn't discovered until after her death. The cause of death was pneumonia due to measles," the health department said.
    It stressed that no one who had contact with any of the known cases remains at risk.
    So far this year, 11 people have been diagnosed with measles in Washington state, including six in Clallam County, according to the health department.
    "The last active case of measles in Washington this year was reported in late April. Within about three weeks of exposure to someone with measles, it's possible to develop the disease. Since more than three weeks has already passed since the last active measles case, no one who had contact with one of the known cases is any longer at risk for developing measles from those exposures," it said.
    Measles is a highly contagious respiratory disease. It causes fever, red and sore eyes, runny nose, cough and a rash. It can cause deadly health complications, including pneumonia and encephalitis. It is spread by contact with an infected person through coughing or sneezing. It can remain in the air and on surfaces for up to two hours.
