One year since we first reported on this coronavirus—what we've learned, and still need to know

A year ago, I wrote an article for The Conversation about a mysterious outbreak of pneumonia in the Chinese city of Wuhan, which transpired to be the start of the COVID-19 pandemic. At the time of writing, very little was known about the disease and the virus causing it, but I warned of the concern around emerging coronaviruses, citing SARS, Mers and others as important examples.
