Jury duty's a pretty important function. It's not a particularly large gathering and keeping people detained for longer without trial (as would be a necessary consequence of stopping jury duty) is a considerable imposition.
It's not an inconceivable measure, but it's not one to be taken remotely lightly - probably not until you ban all gatherings altogether.
Agreed and clearly we start infringing on pretty basic american rights if we wait until summer to stop convening jury's.
That said, reasonable people are avoiding being in closer quarters with sub-1000 people, and it seems like some assurance besides "call if you're so symptomatic you should see a doctor" might be prudent until a little more is known about the virus.
Maybe I'm just salty that I have jury duty this week (:

(To be fair, this morning they added a note saying call first if you are "experiencing any acute respiratory illness")
