coronavirus. SARS-CoV-2. Covid-19

Thanks to Marco Arment for clarifying this:

1. “Coronavirus” is a category of many viruses, not just this one.

2. This virus is “SARS-CoV-2.”

3. The disease it causes in humans is “Covid-19.”

4. Before “SARS-CoV-2” was standardized, the virus was provisionally named “2019 novel coronavirus,” or “2019-nCov.”

The Wall Street Journal adds:

“Coronavirus refers to the virus, not the illness. We have started using Covid-19 more to refer to the disease, as the term has become more familiar.”
