Virus researchers say Ebola could spread through air - and even spread without symptoms

The chorus of U.S. health officials constantly reassuring the public that Ebola can't transmit through the air is quickly tailing off, as virologists and other disease experts say "not so fast." Health experts know very little about the nature of the Ebola strain now in circulation, they say, and it appears as though the current iteration of the disease is much more virulent than previously believed.

Dr. C.J. Peters, a former researcher who worked with the Centers for Disease Control and Prevention (CDC) to study Ebola's transmissibility in humans, is just one of many who now say that airborne transmission of Ebola can't be ruled out as an impossibility. There simply isn't enough data to suggest otherwise, he says.
