Health officials on Monday confirmed four additional coronavirus deaths in Washington, bringing the state’s total death toll to six.
There are 18 confirmed cases in Washington, including the six deaths.
Most of those who have died were elderly or had underlying health conditions.
“Unfortunately, we are starting to find more COVID-19 cases here in Washington that appear to be acquired locally,” said Dr. Kathy Lofy, a health officer for the Washington State Department of Health.
All of the cases are in two adjacent counties: Snohomish and King, which is home to Seattle.
Lofy said the virus could be spreading in other areas of the state, which is ramping up testing to better understand how widespread the virus is in Washington.
