WASHINGTON (AP) — The Biden administration is once more making some free COVID-19 tests available to all U.S. households as it releases its contingency plans with coronavirus cases ticking upward this winter.

After a three-month hiatus, the administration is making four rapid virus tests available per household through covidtests.gov starting Thursday. COVID-19 cases have shown a marked increase after the Thanksgiving holiday, and further increases are projected from indoor gathering and travel around Christmas and New Year's.

Cases are up across 90% of the country, White House COVID-19 coordinator Dr. Ashish Jha said Thursday during a briefing. Deaths and hospitalizations are also on the rise, with nearly 3,000 deaths reported last week. Most of those have been concentrated in people age 65 and older, Jha said.

"We don't want this winter to look like last winter or the winter before," Jha said.

As cases begin to rise again, much of the United States is also dealing with other respiratory viruses heading into this winter with an influx of flu and RSV, or respiratory syncytial virus. Jha told reporters he is confident that the worst of RSV -- which hit young children particularly hard -- is over, but that flu cases are only just spiking.

The administration is putting personnel and equipment on standby should they be needed to help overwhelmed hospitals and nursing homes, as was necessary in earlier waves of the coronavirus. So far, there have been no requests for assistance, but surge teams, ventilators and personal protective equipment are ready, the White House said.

The administration is also urging states and local governments to do more to encourage people to get the updated bivalent COVID-19 vaccines, which scientists say are more effective at protecting against serious illness and death from the currently circulating variants. The administration is reiterating best practices to nursing homes and long-term care facilities for virus prevention and treatment and is urging administrators as well as governments to encourage vulnerable populations to get the new shots. Less than half of all nursing home residents have received the latest booster shot, Jha said.

The planning comes as the administration has struggled to persuade most Americans to get the updated boosters as cases and deaths have declined from pandemic highs and most people have embraced a return to most of their pre-pandemic activities. Less than 14% of people in the U.S. older than have gotten the most recent booster.

The White House said the new tests would come from the national stockpile, which still has reserves even after the administration shut off the at-home testing program in September, citing a lack of money from Congress. The administration is still asking Congress for billions more dollars for the virus response.

The pause on free at-home testing program this summer allowed the administration to save some free at-home tests for the surge in cases this winter, Jha said.
