Timeline: Tracking the Origin of SARS-CoV-2

 

 

The Huanan Seafood Market

 

  1. 1/1/2020: Huanan Seafood Market was closed and cleaned up.
  2. 3/5/2020: Local authority completely remodeled Huanan Seafood Market.
  3. 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

 

  1. 2004: SARS virus escaped twice from laboratories in China.
  2. 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.
  3. 9/18/2019: Wuhan held an emergency response drill for "Novel Coronavirus."
  4. 1/3/2020: A Chinese scientist, Li Ning, was sentenced to 12 years in prison for selling experimental animals to local markets. 
  5. 2/17/2020: China introduced its first biosecurity law. 
  6. 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. 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. 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. 
  3. China never identified its Patient Zero of COVID-19.
  4. 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.
