The Monroe County public health department announced 17 newly confirmed cases of COVID-19 Sunday morning.
In a Sunday afternoon update, the health department confirmed five additional cases, for a local total of 68.
Last Sunday morning, there were two confirmed cases in the county.
The health department has acknowledged that these numbers are undercounting the total number of coronavirus infections in the county.
"There are a limited number of COVID-19 tests available in Monroe County, and not everyone with potential symptoms of COVID-19 can be tested," the department said in an emailed statement.
"For most people, the results of a test for COVID-19 will have no impact on what happens next. Everyone should already be staying home, practicing social distancing, and talking with their healthcare providers to manage any symptoms," the health department said.
Of the 63 known cases, 11 were hospitalized, the county said. As of Sunday afternoon, five of those 11 were in an intensive care unit.
While testing supplies are limited, people whose symptoms have landed them in the hospital are among the groups the county is prioritizing for diagnosis.
"A hospitalized patient who tests negative can be removed from isolation, which saves PPE usage," the county said, referring to the personal protective gear for medical workers that has also been in short supply.
Nearly 300 people were under mandatory quarantine, the county said.
