Omicron outbreak in Navajo Nation sees cases soar
The 27,000-mile reservation, which covers parts of Nevada, New Mexico, and Utah, has reported 294 new infections but no deaths - up from just 10 on Monday.
Cases have spiked since the Omicron variant was confirmed in the territory at the beginning of this week, with infections jumping to 35 on Tuesday, then 168 on Wednesday. President Jonathan Nez said the reservation was "the safest place to be" due to tougher restrictions than U.S. border towns and outside cities.
The rise in new COVID-19 cases is very alarming, but we should not panic because we have the vaccines to help push back on the variants and we know what precautions we have to take to protect ourselves and others. The safest place to be is at home here on the Navajo Nation where we have a face mask mandate, extra precautions in businesses and other safety measures in place that are not in effect in border towns and other cities.
Nurses union says British government can 'no longer deny' NHS crisis
The Royal College of Nursing (RCN) has told Newsweek that "we need to know that the Government isn't compromising" patient safety and accused Prime Minister Boris Johnson of being "dismissive" when asked about NHS staffing problems.
Director for England, Patricia Marquis, said in statement this morning that ministers "can no longer deny" that the latest COVID wave, and a lack of preparation, has triggering a staffing crisis in parts of the health service.
The Government can no longer deny the staffing crisis in the NHS. The Prime Minister and others can no longer be dismissive of questions about the ability of NHS staff to deliver safe care. Once the military has been brought in, where does the Government turn next in a bid to 'ride out' the wave rather than deal with it?
British troops deployed to hospitals in London amid staffing crisis
Around 200 soldiers, including military medics, have been sent to assist healthcare staff with patient care and logistics. Omicron has seen an exodus of workers from hospital units in recent weeks - similarly to the U.S. - at a time when patient numbers are skyrocketing in the U.K. capital.
The country's National Health Service (NHS) has been struggling to keep up with increased demand as COVID patients flood into intensive care following Christmas and New Year celebrations, which saw millions traveling across the country and gathering in large groups.


North Korea withdraws from Beijing Winter Olympics
The country party blamed COVID concerns for its decision but took the opportunity to criticize the U.S. and wish their "Chinese comrades" good luck.
State media reported that North Korea's leadership was agitated by "hostile forces" and suggested the U.S. and its allies are trying to prevent the Games from being a success to embarrass China.
The U.S. and its vassal forces are getting evermore undisguised in their moves against China, aimed at preventing the successful opening of the Olympics ... [it is] an insult to the spirit of the international Olympic Charter and as a base act of attempting to disgrace the international image of China. We could not take part in the Olympics due to the hostile forces' moves and the worldwide pandemic, but we would fully support the Chinese comrades in all their work to hold splendid and wonderful Olympic festival.
Thousands of COVID tests in Chicago schools deemed 'invalid'
Around 36,000 tests were completed between December 26 and January 1 - but 25,000 of them were "invalid" and couldn't be processed, according to data on Chicago Public Schools' (CPS) website.
In-mail COVID kits for CPS students were piled up at FedEx dropboxes last week, CBS Chicago reported, as parents feared many tests wouldn't reach the labs in the 48-hour window to be processed.

One sign read "#FreeNovax" while another claimed that Victoria was "the place to be but only if you are vaccinated" - a criticism of the region's tough COVID rules.
Djokovic's legal team argues that he has the right to a medical exemption but the tennis star has so far refused to explain why, deeming it an invalid excuse by the Australian Border Force, who retracted his visa on Wednesday.
