The Allegheny County Health Department said there were 74 new deaths related to COVID-19 reported in the last 24 hours.
The numbers released Wednesday also show 670 new cases of the virus in the county.
The county said a backlog at the state caused the high number of deaths being reported in the update. The dates of the deaths ranged from December 4 to January 8.
According to the data, 49 of those deaths are associated with long-term care facilities.
County Executive Rich Fitzgerald tells KDKA Radio the COVID vaccination effort is well underway in response.
"We know that over 42 long-term care facilities in Allegheny County have alread seen their folks vaccinated and, I don't know how many are left that haven't been, but they're being reached out to as we speak," he said.
Last week, county health officials said they are starting to see a post-holiday surge in coronavirus cases.
Since March of 2020, there have been 1,178 deaths as a result of the COVID-19 virus.
