Nearly 200 people who attended a catered party at a downtown
Seattle office building have become ill with norovirus, a public
health official said on Monday.
Public health officials closed all the food-service locations
inside the Russell Investments Center in downtown Seattle,
including a Starbucks location, said Dr. Meagan Kay, a medical
epidemiologist for the public health department.
Norovirus can spread by an infected person, contaminated food,
water or contaminated surfaces, the CDC said.
Nearly 200 people out of roughly 600 people who attended the
party catered by California-based Bon Appetit Management Co on
Tuesday reported some level of sickness, Kay said. That number
is likely to go up as the investigation continues into the cause
of the outbreak, she said.
"The source of this illness remains unclear, and we are as eager
as anyone to learn precisely how and when it began," the
catering company said. "We have worked with our food safety
experts to disinfect the surfaces in our facility and have taken
all other necessary steps to ensure food safety."
Two people have been hospitalized overnight and eight people
visited an emergency room for their illness, though the
conditions of the patients were not known, Kay said.
Over the weekend, the building was disinfected in part to
address vomiting in restrooms and to clean door knobs and other
surfaces, Kay said.
The virus causes the stomach or intestines or both to become
inflamed with acute gastroenteritis which leads to stomach pain,
nausea and diarrhea, according to the Centers for Disease
Control and Prevention.
It is the most common cause of foodborne-disease outbreaks and
acute gastroenteritis in the United States, causing some 19
million to 21 million illnesses and 570-800 deaths annually, the
Centers for Disease Control and Prevention said.
A man who identified himself as Bryan said on a health
department blog that he and his wife, who is eight months
pregnant, had become sick. He said he had gone to the emergency
room and received intravenous fluids.
