The scientists said the theories pertaining to accidental leaks from labs and natural spillover are both viable.

Meanwhile, the theory that SARS-CoV-2 escaped from a laboratory in Wuhan has gained traction in the past few weeks.Ī group of 18 scientists even published a letter in the Science journal on 13 May, calling for a more rigorous investigation into the virus origins. The investigations into the disease revealed that construction vehicles had carried mud contaminated with FMD from a defective wastewater line at Pirbright.Īlso read: Before Covid officially hit, 3 at Wuhan lab were hospitalised in Nov 2019, says WSJ report The foot and mouth disease appeared in the UK in 2007, about 4 km from a biosafety level 4 laboratory in Pirbright. The first was in 1972 from the London School of Hygiene and Tropical Medicine, the second was in 1978 from Birmingham Medical School, from where the 1966 smallpox outbreak had also leaked. The virus had leaked from two different accredited smallpox laboratories in the UK. “Virologists and public health officials with the appropriate sophistication were quickly aware that a laboratory release was the most likely origin, but they were content not to publicize this, aware that such embarrassing allegations would likely end the then-nascent cooperation of Russian and Chinese virologists, which was vital to worldwide influenza surveillance.”Īnother virus that leaked from laboratories is the smallpox. On the H1N1 leak, Martin Furmanski, a researcher of the Scientist’s Working Group on Chemical and Biological Weapons, wrote in his 2014 paper that the authorities did not want to publicise the lab origin of the virus. It was found that the virus may have escaped from a lab attempting to prepare an attenuated H1N1 vaccine in response to the US swine flu pandemic alert. Similarly, the H1N1 influenza virus, which first appeared in 1918 as a global pandemic, and reappeared in 1977 probably escaped a lab. In April 2004, the virus escaped from the Chinese National Institute of Virology. The investigation revealed that a SARS research scientist in Taiwan had handled leaking biohazard waste without gloves, a mask, or a gown. The first time a SARS 1 escaped from a virology lab was from Singapore in August 2003 in the National University of Singapore, while the second one happened in the same year in the month of December in Taiwan.
