The coronavirus most likely first appeared in humans after jumping from an animal, a team of international and Chinese scientists looking for the origins of COVID-19 said Tuesday, dismissing as unlikely an alternate theory that the virus leaked from a Chinese lab.
A closely watched visit by World Health Organization experts to Wuhan — the Chinese city where the first coronavirus cases were discovered — did not dramatically change the current understanding of the early days of the pandemic, said Peter Ben Embarek, the leader of the WHO mission.
But it did “add details to that story,” he said at a news conference as the group wrapped up a nearly four-week visit to the city.
And it allowed the joint Chinese-WHO team to rule out one theory on the origins of the virus. The Wuhan Institute of Virology has collected many virus samples, leading to allegations that it may have been the source of the original outbreak, whether on purpose or accidentally.
But experts now consider the possibility of such a leak so improbable that it will not be suggested as an avenue of future study, said Embarek, a WHO food safety and animal diseases expert.
China had already strongly rejected that possibility and has promoted other theories. The Chinese and foreign experts considered several ideas for how the disease first ended up in humans, leading to a pandemic that has now killed more than 2.3 million people worldwide.
Embarek said the initial findings suggest the most likely pathway the virus followed was from a bat to another animal and then to humans, adding that would require further research.
“The findings suggest that the laboratory incidents hypothesis is extremely unlikely to explain the introduction of the virus to the human population," he said.
The mission was intended to be an initial step in the process of understanding the origins of the virus, which scientists have posited may have passed to humans through a wild animal, such as a pangolin or bamboo rat. Transmission directly from bats to humans or through the trade in frozen food products are also possibilities, Embarek said.
The WHO team's visit is politically sensitive for Beijing, which is concerned about being blamed for alleged missteps in its early response to the outbreak. An AP investigation has found that the Chinese government put limits on research into the outbreak and ordered scientists not to speak to reporters.
The team — which includes experts from 10 countries who arrived on Jan. 14 — visited the Huanan Seafood Market, the site of an early cluster of cases in late 2019.
Marion Koopmans, a Dutch virologist on the team, said that some animals at the market were susceptible or suspected to be susceptible to the virus, including rabbits and bamboo rats. And some could be traced to farms or traders in regions that are home to the bats that carry the closest related virus to the one that causes COVID-19.
She said the next step would be to look more closely at farms.
Liang Wannian, the head of the Chinese side, said the virus also appeared to have been spreading in other parts of the city than the market, so it remains possible that the virus originated elsewhere.
The team found no evidence that the disease was spreading widely any earlier than the initial outbreak in the second half of December 2019.
“We haven’t been able to fully do the research, but there is no indication there were clusters before what we saw happen in the later part of December in Wuhan,” Liang said.
Another member of the WHO team, British-born zoologist Peter Daszak, told The Associated Press late last week that they enjoyed a greater level of openness than they had anticipated, and that they were granted full access to all sites and personnel they requested.
The visit by the WHO team took months to negotiate. China only agreed to it amid international pressure at the WHO's World Health Assembly meeting last May, and Beijing has continued to resist calls for a strictly independent investigation.
While China has weathered some localized resurgences of infection since getting the outbreak under control last year, life in Wuhan itself has largely returned to normal.

Jennifer Lotito, president and COO at the non-profit (RED), joined Cheddar to discuss the CODE (RED) campaign as the organization looks to expand its mission to support both AIDS and COVID-19 relief. She explained that people can get involved in the campaign for Giving Tuesday and ahead of World AIDS Day by shopping (RED) branded products and even using credit card rewards points to add their own support. Lotito also pointed out that COVID-19 has also impacted HIV testing as people avoid clinics out of fear of the other pandemic.
NASA indefinitely delayed a spacewalk to repair an ISS antenna, citing concerns about space debris. It was unclear if the warning from the space agency to astronauts aboard the ISS was related to the recent destruction of a non-functioning Russian satellite.
Dr. Farhan Bhatti, a family physician and Michigan State lead for the Committee to Protect Health Care, joined Cheddar to discuss the newly discovered and highly transmissible omicron variant of COVID-19. Bhatti said it is too early to draw any conclusions about the new variant but there is concern that it could eventually mutate and develop a resistance to vaccines. "Time will tell, but for now, it looks like, still, the best thing that we can do to try to limit the spread of this disease is make sure everybody gets a vaccine and make sure everybody avoids large gatherings indoors and wears masks during the wintertime especially," he said.

Friday saw big sell offs, with the Dow Jones posting its worst day since October 2020, falling 905 points, with the Nasdaq and S&P 500 each tumbling more than two percent as well. Much of that due to investor concerns over the new Covid-19 'Omicron' variant first detected in South Africa.

The ocean is an important topic when it comes to the climate. It plays a vital role in shaping our environment, with rising sea levels causing a 35% increase in natural disasters around the world, affecting 1.7 billion people. Dr. Sylvia Earle has been called perhaps the greatest advocate our oceans have ever had, with Time magazine dubbing her its first 'hero of the planet' and the Library of Congress naming her a living legend. She is also the founder of Mission Blue, an organization that inspires action to explore and protect the ocean. Dr. Earle joined Cheddar Climate for more on the importance of caring for the ocean and its impact on climate change.
Scientists are racing to understand the Omicron variant of covid-19 and find out just how dangerous it really is. Omicron, dubbed a variant of concern by the WHO, was first detected in South Africa last week and has already spread to multiple countries, including the UK, Canada, Australia and more. Dr. Jonathan Javitt, CEO of Nrx and adjunct professor at Johns Hopkins School of Medicine, joined Cheddar to discuss what we know and don't know about this new variant.
