The US coronavirus death toll is now up to six — including four elderly residents from the same nursing home in Washington state, authorities said Monday.

Officials had reported that two people, including a man in his 50s, died from the virus in Washington over the weekend — then upped the death toll Monday to add four more, all also in the state.

At one point during a press conference announcing the new deaths Monday, state health officials appeared confused as to the final tally, CNBC reported.

Dr. Kathy Lofy, the state’s health officer, first revealed a total of five deaths — only to have Dr. Ettore Palazzo, the chief medical officer at EvergreenHealth Medical Center, where many of the victims died, correct her, adding one she was unaware of.

“So six should be the correct number,” Lofy told reporters. “We were, at the department, aware of the five deaths from King County. We had not received the report about the Snohomish County patient just yet … apologize for that.”

At least three of the newly reported deaths involved residents of the Life Care Center nursing home in the Seattle suburb of Kirkland in King County, and included a man in his 70s and woman also in her 70s, both of whom had underlying medical conditions, KCPQ-TV of Seattle said.

A fourth person from the nursing home also died from the virus, the LA Times reported, although it wasn’t immediately clear whether the victim was among the most recent deaths or one of the two who previously perished.

Five of the six victims hailed from King County, while the sixth was from neighboring Snohomish County, officials said.

A rep for the nursing home was unable to be reached Monday. But its executive director previously said in a statement to KIRO-TV, “Residents are our highest priority at Life Care Center of Kirkland. Their safety and well-being are our primary concerns.

“Current residents and associates are being monitored closely, and any with symptoms or who were potentially exposed are quarantined.”

Medical researchers have said it appears that the virus had been silently spreading in the state for nearly six weeks before claiming the country’s first victim there over the weekend.
