It has been more than 300 days since Chinese authorities first told the World Health Organisation that Wuhan residents were sick with a mysterious virus. Scientists discovered soon what the virus was (a coronavirus) and what it did (make people ill with a disease called COVID-19), and it spread across the globe like flames.

More than 1 million people have died worldwide, hundreds of thousands get sick every day, and the United States is the world’s most significant disease.

Researchers were still unsure how the virus spread, why people were infectious, or whether one could get it twice when we released our first guide to the coronavirus. These questions may have some residual confusion, but scientists have made some remarkable strides in responses.
