So let's take your specific tweet here:
He claims recode said :
> "cases...have been contained to those who have recently traveled to Wuhan and their direct family members"
What recode actually said:
> "Public Health officials in the area have said there's currently a low risk to public health; the cases they say, have been contained to those who have recently traveled to Wuhan and their direct family members"
I don't want to accuse you of being disingenuous or what-not,but really? Pretending something is a direct claim of Vox, when actually it's a claim that they're reporting from public health officials in Silicon Valley is a dramatic mis-representation.
Ok, so let's lay aside what I think is mis-representation. The things that this tweeter seems to be claiming are counter points:
>"We're probably going to see human-to-human cases within the united states" Dr Robert Redfield said in an interview with stat.
A claim about the current situation within Silicon Valley cannot be countered with a forward looking statement about the entire US. It just can't. I just don't think this criticism is serious.
