The theory that the coronavirus outbreak was caused by a laboratory leak should be taken seriously until proven wrong, leading scientists said.
Covid-19, which emerged in Wuhan, China in late 2019, has killed 3.34 million people, cost the world trillions of dollars in lost income and upended normal life for billions of people.
Eighteen scientists from prestigious universities including Cambridge and Stanford, wrote in a letter to Science magazine that "more investigation is still needed to determine the origin of the pandemic".
"Theories of accidental release from a lab and zoonotic spillover both remain viable," they wrote.
“Knowing how Covid-19 emerged is critical for informing global strategies to mitigate the risk of future outbreaks.”
The authors of the letter said the World Health Organisation's investigation into the origins of the virus had not made a "balanced consideration" of the theory that it may have come from a laboratory incident.
In its final report, written jointly with Chinese scientists, the WHO-led team that spent four weeks in and around Wuhan between January and February said the virus had probably been transmitted from bats to human beings through another animal, and that a lab leak was "extremely unlikely" as a cause.
But there are myriad different ideas about the origin of the virus, including numerous conspiracy theories.
The scientists, who include researchers Jesse Bloom and Ravindra Gupta, said “we must take hypotheses about both natural and laboratory spillovers seriously until we have sufficient data”.

"A proper investigation should be transparent, objective, data-driven, inclusive of broad expertise, subject to independent oversight, and responsibly managed to minimise the impact of conflicts of interest," they wrote.
"Public health agencies and research laboratories alike need to open their records to the public. Investigators should document the veracity and provenance of data from which analyses are conducted and conclusions drawn, so that analyses are reproducible by independent experts."
The scientists called on the international community to rally behind the cause.
"In this time of unfortunate anti-Asian sentiment in some countries, we note that at the beginning of the pandemic, it was Chinese doctors, scientists, journalists and citizens who shared with the world crucial information about the spread of the virus – often at great personal cost,” they said.
"We should show the same determination in promoting a dispassionate science-based discourse on this difficult but important issue."

Why are asylum seekers being housed in hotels?
The number of asylum applications in the UK has reached a new record high, driven by those illegally entering the country in small boats crossing the English Channel.
A total of 111,084 people applied for asylum in the UK in the year to June 2025, the highest number for any 12-month period since current records began in 2001.
Asylum seekers and their families can be housed in temporary accommodation while their claim is assessed.
The Home Office provides the accommodation, meaning asylum seekers cannot choose where they live.
When there is not enough housing, the Home Office can move people to hotels or large sites like former military bases.

'The worst thing you can eat'
Trans fat is typically found in fried and baked goods, but you may be consuming more than you think.
Powdered coffee creamer, microwave popcorn and virtually anything processed with a crust is likely to contain it, as this guide from Mayo Clinic outlines:
Baked goods - Most cakes, cookies, pie crusts and crackers contain shortening, which is usually made from partially hydrogenated vegetable oil. Ready-made frosting is another source of trans fat.
Snacks - Potato, corn and tortilla chips often contain trans fat. And while popcorn can be a healthy snack, many types of packaged or microwave popcorn use trans fat to help cook or flavour the popcorn.
Fried food - Foods that require deep frying — french fries, doughnuts and fried chicken — can contain trans fat from the oil used in the cooking process.
Refrigerator dough - Products such as canned biscuits and cinnamon rolls often contain trans fat, as do frozen pizza crusts.
Creamer and margarine - Nondairy coffee creamer and stick margarines also may contain partially hydrogenated vegetable oils.
