December 1, 2019 — The first known case of COVID-19 is detected

The first official case of what would be designated as Covid 19 (Coronavirus disease 2019) was detected in the city of Wuhan, located in Hubei province China. In the year to come, it would spread quickly around the world, killing hundreds of thousands of people and infecting millions more – and although a majority of those who caught it recovered, many of these would be left with permanent damage it had caused.

In short order, the World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January, 2020, and upgraded that designation to pandemic on 11 March, 2020. It is the single greatest pandemic since the Influenza Pandemic almost exactly a century earlier.
