The Monroe County health department said Sunday that a sixth person had died of COVID-19 in the county as 21 new cases were confirmed over the last 24 hours.
Five of those new cases are in people in their 20s.
"Please keep the family and friends of the deceased in your thoughts and prayers as we continue to work as a community to slow the spread of the virus," county public health commissioner Dr. Michael Mendoza said in a statement.
"Please continue staying at home and practice social distancing when you must go out for essential purposes."
The county now has a total of 223 confirmed cases of COVID-19, though limited testing supplies mean that remains an undercount of the extent of the disease's spread.
Nearly 50 people who were confirmed to have COVID-19 in the county have gotten better and been released from mandatory isolation.
More than 350 people remain in mandatory quarantine and isolation, but the county encouraged everyone to act as though they were infected and contagious.
"We should all assume that we have been exposed to COVID-19, even if we do not have recognizable symptoms, and could be spreading the virus to people who are vulnerable to more severe symptoms," the public health department said in a statement.
