The CDC announced today that the only person who seemed to have contracted MERS from a patient within the US actually never caught the virus at all.
The agency found this out from a more definitive type of MERS test.
This means that no one who has had MERS in the US has passed it on to anyone else, or at least not that we know of. As of right now, there are no people infected with MERS in the US, although cases continue to add up abroad.
