Dr. Peter Ben Embarek, the head of the WHO team, which travelled to China in a live press briefing on Tuesday, said that there was no evidence to show that the virus was manufactured in a laboratory. He says their investigation shows that the virus came from a zoonotic source most likely a bat.
COVID-19 virus that has infected over 100 million people globally causing at
least 2,327,231 deaths did not start in a laboratory, according to a report
released by the World Health Organization.
report shows that the virus is predominant in bats and as such probably came
from bats but not the laboratory as has been suspected by many. The
findings are from a one-month epidemiological tracing mission in Wuhan, China
to identify the source of the virus and how it was introduced to humans.

on, it was believed that the disease could have originated from bats or
pangolins. Other theories pointed towards the virus being manufactured in
laboratory most likely the Wuhan Institute of Virology where a lot of work
into coronavirus research is carried out. However, the UN health agency, says laboratories
are not the source of the virus since no spills were reported.

still unclear how humans might have been exposed to the virus. The report
reveals three possible theories through, which humans might have been exposed
to the virus. The
first theory is that there was a direct link between humans and the
disease-carrying animal, in this case, a bat.
The second theory is that the virus
was transported by an intermediary host, in this case, an animal that acted as
a host of the virus before it was passed on to humans while the third is that
the virus was transmitted through cold chain where an infected animal with the
disease was kept with other animals at the Huanan wholesale seafood center, which
is believed to be the location of one of the first transmission clusters of the

findings from the investigations reveal that cases of the disease were reported
from other markets before the disease was discovered at Huanan market. The
first case in Huanan market is believed to have been reported on December 12,
2019, while some of the earliest cases that took place as early as December 8,
2019, took place at other markets.
don't know the exact role of the Huanan market. We know that people who visited
the market throughout December were infected but we do not know how the virus
could have gotten to the market. However, we also know that there was spread of
the disease to individuals traced to other markets that were not Huanan market.
But we are working with the hypothesis that the virus entered the market
through a visitor or killed wildlife products stored in the cold chain,"
Dr. Embarek said.
from the study also reveal that the first infections in Wuhan are likely to
have happened in the first two weeks of January 2020. The first cases of
COVID-19 were reported as a cluster of cases of pneumonia in Wuhan by WHO on
December 31, 2020.
declared the outbreak a Public Health Emergency of International Concern in
January after other countries began reporting cases. The disease was later
declared a pandemic in March 2020. As studies continue to trace how the virus
got into contact with humans, vaccinations against the disease are ongoing in
many parts of the world.
