A pneumonia of unknown cause detected in Wuhan, China was first reported to the WHO Country Office in China on 31 December 2019. That is less than 3 months ago as I draft this. This new corona virus was only given a name on February 11th 2020.
Now many people across the world are working from home where possible, avoiding close contact with others and living in isolation because of this virus that until a few months ago was unheard of.
