On March 18, Mingpao published an opinion piece entitled “This pandemic originated in Wuhan, the lessons of seventeen years ago have been completely forgotten.” The authors Dr. Kwok-Yung Yuen and Dr. David Lung are unrivalled experts in their field. Dr. Yuen is a microbiologist whose SARS study group discovered the role of the coronavirus in the SARS epidemic in early 2003. Dr. Lung is also a microbiologist who has recently published on the detection of COVID-19 via saliva samples.
In their article, the authors offer practical advice on understanding the virus for the general reader. First, they explain how the World Health Organization and the International Committee on Taxonomy of Viruses name viruses, while also acknowledging that the colloquial use of “Wuhan pneumonia” is understandably more straightforward than COVID-19 or SARS-CoV-2 and thus does not need to be condemned.
Second, Yuen and Lung explain that genetic sequencing has shown the virus likely originated in horseshoe bats before spreading to an intermediate host in the Wuhan Seafood Market (most likely endangered pangolin), which then served as an amplification epicentre spreading from animals to humans, before mutating to enable human-to-human transmission.
