The first person to be infected with Covid-19 may have been a Wuhan laboratory employee, a World Health Organisation official has claimed.
Dr Peter Embarek, the epidemiologist who led the WHO’s four-week investigation into the origins of the virus has said that a probably hypothesis is that a lab employee was infected while taking samples from bats in the field.
“This is where the virus jumps directly from a bat to a human,” he told Danish TV2, “in that case, it would then be a laboratory worker instead of a random villager or other person who has regular contact with bats.”
He added however, that the WHO had found no direct evidence that the coronavirus outbreak was linked to the bat research conducted in Wuhan’s laboratories.
Meanwhile, new research has found that those pinged by the NHS app in England and Wales are four times more likely to have Covid-19 than someone who has not been pinged.
A survey of more than 750,000 found that people who were alerted by the app and told to self-isolate were between 3.7 to 4.0 times more likely to have the virus. It also found that younger groups who were told to self-isolate were more likely to be positive compared with older age groups.
