COVID-19 hospitalizations are increasing in Quebec and Quebec Premier François Legault says the biggest challenge is staffing.

"To get through the next few weeks, we're going to need 1,000 more employees in hospitals and 1,500 more employees" at one of Quebec's long-term care facilities, Legault wrote on Facebook.

About 10% of adults in Quebec are unvaccinated, but they make up half of the COVID-19 ICU hospitalizations.

"This means that unvaccinated adults are nine times more likely to be hospitalized than vaccinated adults. This is a huge burden on our health network," he said. "This is why we are considering a payable health contribution for all adults who refuse, for non-medical reasons, to get vaccinated," he said.

"The amount has not been decided yet, but it will be a significant amount," he added.

The vast majority of law enforcement deaths last year -- 301 out of a total 458 deaths -- were due to COVID-19, the second year in a row COVID-19 was the leading cause of line-of-duty deaths, according to a new report from the National Law Enforcement Memorial Fund.

"Law enforcement officers nationwide continue to be exposed to the Covid-19 virus in the course of their daily assignments; therefore, the number of line-of-duty deaths is sadly ever-increasing," the report said.

The vaccination status of the 301 officers who died is not known.

The CDC says it plans to update its mask guidance to “best reflect the multiple options available to people and the different levels of protection they provide.”

The CDC did not say when its guidance will be updated. In the meantime, the CDC said in a statement, “any mask is better than no mask, and we encourage Americans to wear a well-fitting mask to prevent the spread of COVID-19.”

Since the arrival of omicron, health experts have urged Americans to upgrade their cloth masks to an N95 or KN95 because the new variant is so highly transmissible. But these higher-grade masks are costly and hard to find.

Prior to omicron, CDC director Rochelle Walensky resisted suggesting N95 masks for the average American because the CDC didn’t want to discourage people from wearing any mask.

Dawn O’Connell, a top official at the Health and Human Services Department, said Tuesday that the Biden administration plans to increase production of N95s. There are already 737 million N95 masks in the strategic national stockpile available for medical workers.

Forecast models used by the CDC suggests COVID-19-related deaths will significantly increase over the next four weeks.

The model forecasts that 22,000 more Americans could die from COVID-19 in just the next two weeks.

The CDC obtains these forecasts from the COVID-19 Forecast Hub at UMass Amherst, where a team monitors and combines forecasting models from the nation’s top researchers. The team then creates an ensemble -- displayed like a hurricane forecast spaghetti plot -- usually with a wide cone of uncertainty.

Russian officials are warning that an omicron-fueled wave of COVID-19 infections will soon hit, amid fears about how deadly a surge of the highly contagious variant -- even if milder -- might be in a country with a low vaccination rate.

Russian Deputy Prime Minister Tatiana Golikova, who is overseeing the COVID-19 response, and Moscow Mayor Sergey Sobyanin said Wednesday that the situation could be "more critical" than previous waves of infections in Russia -- a worrying prospect since earlier waves led to a high number of deaths.

Russia has reported more than 312,000 fatalities from COVID-19 since the start of the pandemic, according to data compiled by Johns Hopkins University. However, the country registered just under 1 million excess deaths in 2021.

The Russian government has said the country will soon see six-figure daily cases. Less than 50% of Russians are fully vaccinated against COVID-19, amid widespread reluctance across the nation.

Russian President Vladimir Putin, who has largely tried to downplay the scale of his country's COVID-19 outbreak, warned Wednesday of the imminent increase in infections. Putin said Russia is "on the threshold of possible new outbreaks."

Meanwhile, Russian Health Minister Mikhail Murashko said the country is at a "turning point," which will decide how bad the wave will be. Russian authorities are calling for people to take precautions and observe social distancing measures. However, there are relatively few restrictions in most parts of the country.

Denis Logunov, deputy director of Russia's Gamaleya National Center of Epidemiology and Microbiology, said Tuesday that the nationwide number of omicron cases is expected to rise considerably in late January and early February. The World Health Organization's regional director for Europe, Dr. Hans Kluge, also warned Tuesday that omicron is expected to infect more than half of Europe's population within the next two months.
