Coronavirus - Japan chief cabinet secretary Suga: 13 are unwell who returned to Japan on the 2nd flight

News related to the first flight back home is here:

• 3 of the Japanese who returned from Wuhan on the govt flight are confirmed as having coronavirus
• More on the 3 Japanese returned from Wuhan who tested positive for the coronavirus
• Coronavirus - Japan official questions earlier statement

Suga now on flight 2:

• 13 people are unwell

Maybe not just airline food this time?

And, via Reuters citing a "Japan medical expert"

• there is a possibility that coronavirus can be transmitted from people without symptoms
• it has been confirmed in china that coronavirus can be transmitted from people without symptoms

I reckon I am not out on a limb saying no-one knows what is going on with this.
