Here, we’ve tried to distill it into 12 key aspects of this crisis that everyone should understand. That said, we don’t cover everything, and there’s still a lot of uncertainty about some of the most important things on the list. (If you think you have Covid-19, and are curious about what that means for you, read this explainer. If you’re most confused about the financial crisis the virus is causing, read this one.) This guide focuses mostly on the properties of the virus, and the implications for public health.
In the few months since this virus emerged, we’ve learned an immense amount about it. Scientists have decoded its genetics and whom it’s more likely to kill, and have started working on vaccines that could immunize humans to it. Still, its newness means that a lot of the figures presented in this article are estimates and subject to change as scientists learn more. So keep that in mind, too.
1) SARS-CoV-2 is very contagious, and a huge portion of the global population is vulnerable
One thing we do know is that this coronavirus, SARS-CoV-2, is very contagious. Just look at the headlines: Covid-19, the disease caused by the virus, has now infected nearly a million people around the globe.
Scientists quantify the contagiousness of a disease with a figure called R0 (pronounced R-nought.) “The figure refers to how many other people one sick person is likely to infect on average in a group that’s susceptible to the disease (meaning they don’t already have immunity from a vaccine or from fighting off the disease before),” Vox’s Julia Belluz explains. An R0 of 2, for example, means each infected person is expected to spread the virus to two others, on average. Covid-19 is currently believed to have an R0 between 2 and 2.5.
