If panic means, shut down flights from West Africa, cancel Visas to the US and screen all incoming persons, I’m ok with panic.
If panic means run into his boyfriend’s bedroom and hide his head under the covers until the boyfriend brings a nice strawberry daiquiri, which is what Shep probably sees as a panic response, then I would agree.
But that's rasis and ebolaphobic and will cause it to spread faster. (I hope I covered all the PC talking points.)
