Glimpses into China's World of Pathogen Control & Contact Tracing Glimpses into China's World of Pathogen Control & Contact Tracing

Wuhan, the location of the start of the COVID-19 pandemic, now becomes the backdrop to a frenzy of mass testing as the entire 12 million population will be mass tested for cases of the highly transmissible Delta variant of SARS-CoV-2. That’s because, on Monday of this week, local authorities identified three cases of the Delta variant in Wuhan and a few other regions across China, including Beijing, over the past couple of weeks. In a scene harkening back to the beginning of the pandemic here, the city has allocated industrial and technology sections of the city as testing zones, thus transforming the city’s look into some kind of eerie sci-fi looking reality.

Depending on what media one believes, China’s now home to anywhere from 328 to over 400 Delta variant COVID-19 cases since July 20, 2021, when a flight from Russia to Nanjing brought the pathogen to the country according to what an elaborate forensic effort has assessed thus far. Chinese press such as Xinhua reports that thanks to a holistic viral genome sequencing effort, the health authorities have determined that all the strains in the recent COVID-19 resurgence were of the highly infectious Delta variant.
