Timeline: Tracking the Origin of SARS-CoV-2
The Huanan Seafood Market
- 1/1/2020: Huanan Seafood Market was closed and cleaned up.
- 3/5/2020: Local authority completely remodeled Huanan Seafood Market.
- 5/12/2020: The Chinese Disease Control Center said animal samples from the market (collected between 1/1 - 1/12/2020) had no infection of SARS-CoV-2, thus ruled out the possibility that the Huanan Seafood Market was the origin of COVID-19.
Biosafety in China
- 2004: SARS virus escaped twice from laboratories in China.
- 2015: Wuhan Institute of Virology published their successful research on whether they can genetically modify a bat coronavirus to infect human cells. The team engineered a hybrid virus, combining a bat coronavirus with a SARS virus. The hybrid virus was able to infect human cells.
- 9/18/2019: Wuhan held an emergency response drill for "Novel Coronavirus."
- 1/3/2020: A Chinese scientist, Li Ning, was sentenced to 12 years in prison for selling experimental animals to local markets.
- 2/17/2020: China introduced its first biosecurity law.
- 4/15/2020: Chinese authority ordered that all research about the origins of COVID-19 need approval from the government before researchers submit them to international scientific journals.
Mysterious Patient Zero
- 1/24/2020: A Lancet research article indicated that 13 of the first 41 cases of COVID-19 had no link to the Huanan Seafood Market.
- 2/18/2020: BBC News published a Chinese report interviewing one of the authors of the Lancet article. She mentioned the first patient identified in Wuhan was ill on 12/1. The patient had been at home for months because of stroke and Alzheimer's disease. He had never been to the Huanan Seafood Market.
- China never identified its Patient Zero of COVID-19.
- Scientists have not identified the animal host of SARS-CoV-2. Multiple research studies showed that the virus has the highest affinity with human cells.
