COVID-19, to be more accurate.
The thing that really troubles me about this is that it lasts SO LONG. Most people who have gotten it are still sick.
In terms of how disruptive it is, then how long people are ill is a big deal.
I haven't read anything clear about that how long people are infectious after they show symptoms...but it's got a 2-week+ incubation period (as long as 24 days) when people are infectious but asymptomatic.
According to this, though, it's currently considered slightly more infectious than the common seasonal flu.

@tyghebright That 2 week incubation period is the bad aspect.
