We don't actually know that this is happening all over the world. The most we know is that something similar may have happened in San Diego(?) due to the news report and that it has spread to the surrounding area of L.A., due to Fort Irwin being on high alert.

There have been no other reports as to if there are actually other Smart Ones of the caliber that Mr. Suit is, so we also do not know if the other cities, if it has happened there, have any smart ones, jumpers, behemoths, little ones etc. if they are even there it may be just run of the mill Biters.
