Let us see if China is willing to test blood samples from October 2019 as requested by WHO.
If the 90 Chinese that suffered COVID like disease in September 2019 is confirmed to have been infected by COVID-19
then it explains the mystery illness in Europe and US late 2019.
Please don't say Fort Detrick - WHO already ruled out COVID came from a LAB.

During the WHO delegation’s visit, investigators said they received medical records from Chinese authorities related to about 92 cases of people from the 233 institutions canvassed by Chinese authorities across Hubei. All 92 had suffered from pneumonia or other Covid-19-like symptoms. Chinese authorities subjected those patients to antibody tests in recent months.
About a third had died or refused to participate, said Dr. Embarek. The rest tested negative in serology tests that look for antibodies, he and other team members said.
“The numbers are not so important. What is important is that we don’t really know how reliable serology testing is to detect antibodies for SARS-CoV-2 more than a year after infection,” Dr. Embarek said. Another WHO researcher, microbiologist Fabian Leendertz, said the probability of finding antibodies that late would be low.
If the 90 cases included Covid-19 infections, it could help explain suspected coronavirus cases that researchers believe occurred in Europe and possibly the U.S. in November and December 2019.
About 90 people were hospitalized with coronavirus-like symptoms in the country in the two months before the virus’s detection in Wuhan, said World Health Organization researchers who pressed Beijing for further study.
