Coronavirus claimed its first East Coast victims — two seniors in Florida — as the number of cases in the U.S. climbed to 340 Saturday.

Both people who died were in their 70s, had traveled overseas and had tested positive for the disease, the Florida Department of Health said in a statement.

One was a man with underlying health issues in Santa Rosa County in the state’s Panhandle. The second was in Lee County, near Fort Myers on the Gulf Coast.

Their deaths bring the US toll from the virus to 17, including 14 in Washington State and one in California.

At least 340 people in the US have been confirmed to have coronavirus, and eight have recovered, according to a tracker maintained by Johns Hopkins University.

More than half the states have reported cases, with the latest appearing in Pennsylvania, Indiana, Minnesota and Nebraska. Several states have declared emergencies as they try to limit the spread of the virus.

Most cases in the U.S. remain on the West Coast, but the pace of diagnosis is increasing as states ramp up testing.
