Jakarta, CNN Indonesia –
Mission of the expert team WHO of porcelain could not find origins corona virus. However, they agreed that the virus likely passed from bats to unknown animals and then to humans.
A team of experts from China also concluded that it was “highly unlikely” that the virus originated from a leak at a high-security laboratory in the central city of Wuhan.
Pressure engulfs the WHO team during an investigation into China. Even one of the expert team, Peter Daszak, described working in a very political environment.
After a mission that lasted almost a month, here are five things the public still doesn’t know about the origins of the corona virus. AFP.

Experts say the tests were carried out on tens of thousands of samples consisting of wild animals, farm animals and domestic animals throughout China. However, the results did not contain the SARS-CoV-2 virus as the cause of Covid-19.
But Dutch virologist and WHO team member Marion Koopmans said the species most susceptible to the virus, including bamboo rats, civets and rabbits, were sold at the Huanan market in Wuhan. The first place where the virus group was found. From there, it can be an entry point to re-investigate.
Daszak also said that the bat virus, found in Thailand and Cambodia, shifted his team’s focus to Southeast Asia.
“I think one day we will find that (reservoir), it may take some time, but it will certainly be there,” he told reporters.
Raw data
Danish epidemiologist and team member Thea Kolsen Fischer said the WHO team did not receive raw data, it only relied on previous analyzes from China.
Members of the WHO team do not deny it. He said they were given full access to the sites and people they were asked to visit.
Cold chain transmission
China has repeatedly argued that the virus arrived in China through packaging in cold chain products, such as imported frozen seafood, which has been linked to recent domestic outbreaks. However, the WHO denied it.
“There is no evidence that food or the food chain is involved in transmission,” said Mike Ryan, WHO chief of emergencies.
The Chinese team’s mission chief Liang Wannian said the virus may spread deep into the surface of cold chain products and environmental samples from the Huanan market. The market sells frozen seafood and wildlife.
WHO team leader Peter Ben Embarek cautioned that there was no clear evidence that the virus could be passed to humans from contaminated surfaces in the cold chain.
Are you coming from outside China?
China has repeatedly asked the WHO to carry out research on the origins of the virus in the United States.
By defending itself against international criticism over its handling of the outbreak, China strengthened its study which showed that Covid-19 cases increased in Italy and other countries in late 2019.
But in publishing the report’s findings, Koopmans said the study did not provide complete evidence of past circulation outside of China in early December.
Still, he acknowledged that experts should go looking for evidence of the virus’s previous circulation.
Future plan
Koopmans said that the farm supplying wild animals to the Wuhan Huanan market deserves further investigation, in addition to sampling more wild animals.
Ben Embarek suggested retesting the samples using a new approach to blood tests and looking for more early cases undetected in Wuhan.
Meanwhile, China wants more levels of research into virus sources in other countries.
