Isn’t it presumptuous to say “till date no human has been infected”?  Clearly, the virus infects humans, so in reality, thousands of humans may have been infected and were just never diagnosed due to ignorance.

Also, Dr. Morris says the virus has been around for five or six decades and is native to Florida. Doesn’t “native” imply it’s been here much longer.  If it was only identified in 1964, that doesn’t mean that’s when it first appeared. Couldn’t it have been in Florida for hundreds or thousands of years before humans discovered it?

I don’t mean to sound like I’m nit picking, but I’m a victim of bad assumptions in the field of medicine, and I continue to be astonished at conclusions that are drawn and statements that are made that aren’t facts, but are actually assumptions... such as the belief that the Keystone virus doesn’t infect humans. Such statements should always include the disclaimer “that we’re aware of.”
