An Illinois man has the first known case of human-to-human spread of the MERS virus to someone who had come from the Middle East. And while the disease was apparently transmitted casually, it may not be as scary as it sounds.
The CDC and WHO claim they are hard at work tracking 100 people that may have come in contact with the deadly MERS virus.
Officials said the second confirmed case is located at a hospital in Orlando, Fla. The first was reported earlier this month in Indiana, involving a man who arrived from Saudi Arabia.
