It's rumored to be airborne. That would be bad.
Right now it appears to be transmitting through the homosexual community, like staph. I'm no epidemiologist, so I don't know whether that rules out an airborne vector. I will say the spread pattern looks either bioterrorism or airborne, although a gay superspreader event might also explain it.
My best guess is it's bioterrorism looted from a Ukraine lab, and this is the initial scare to create the epidemiological preparation for release of an airborne smallpox variant: manufacture vaccines and consent.
