The quickly changing coronavirus has spawned yet another super contagious omicron mutant that's worrying scientists as it gains ground in India and pops up in numerous other countries, including the United States.

Scientists say the variant – called BA.2.75 – may be able to spread rapidly and get around immunity from vaccines and previous infection. It's unclear whether it could cause more serious disease than other omicron variants, including the globally prominent BA.5.

Hong Kong announced Thursday it is shelving a COVID-19 measure that has resulted in dozens of canceled flights in recent months and thwarted travel plans for thousands.

Starting Thursday, the city will no longer ban arriving airline flights just because they'd brought in passengers infected with COVID-19, the government announced.

The Chinese capital has issued a mandate requiring people to show proof of COVID-19 vaccination before they can enter some public spaces including gyms, museums and libraries, drawing concern from city residents over the sudden policy announcement and its impact on their daily lives.

The health app that shows a person's latest PCR test results has been updated to make it easier to also access their vaccination status, according to Li Ang, a spokesperson for Beijing's municipal health commission.

Of the hundreds of thousands of Muslims arriving in Mecca this week for the annual hajj pilgrimage, perhaps none had a more arduous journey than Adam Mohammed, a 53-year-old electrical engineer from the United Kingdom.

On a bright moonlit night, a team of scientists and volunteers head out to a protected beach along the Delaware Bay to survey horseshoe crabs that spawn in their millions along the U.S. East Coast from late spring to early summer.

The number of new coronavirus cases across Britain has surged by more than 30% in the last week, new data showed Friday, with cases largely driven by the super infectious omicron variants.

Data released by Britain's Office for National Statistics showed that more than 3 million people in the U.K. had COVID-19 last week, although there has not been an equivalent spike in hospitalizations. The number of COVID-19 deaths also fell slightly in the last week.

North Korea suggested Friday its COVID-19 outbreak began in people who had contact with balloons flown from South Korea — a highly questionable claim that appeared to be an attempt to hold its rival responsible amid increasing tensions over its nuclear program.

Activists for years have flown balloons across the border to distribute hundreds of thousands of propaganda leaflets critical of North Korean leader Kim Jong Un, and North Korea has often expressed fury at the activists and at South Korea's leadership for not stopping them.

At a tourism conference in Phuket last month, Thailand's prime minister looked out at attendees and posed a question with a predictable answer.

"Are you ready?" Prayuth Chan-ocha asked, dramatically removing his mask and launching what's hoped to be the country's economic reset after more than two years of coronavirus-driven restrictions. When the crowd yelled its answer — yes, according to local media — it might have been speaking for the entire pandemic-battered world.

The number of new coronavirus cases rose by 18% in the last week, with more than 4.1 million cases reported globally, according to the World Health Organization.

The U.N. health agency said in its latest weekly report on the pandemic that the worldwide number of deaths remained relatively similar to the week before, at about 8,500. COVID-related deaths increased in three regions: the Middle East, Southeast Asia and the Americas.

China on Tuesday reduced the length of mandatory quarantine for inbound travellers, in the biggest relaxation of entry restrictions after sticking to a rigid zero Covid policy throughout the pandemic.
