Canadian scientists have shown that the deadliest form of Ebolavirus could be transmitted by air between species.
In experiments, they demonstrated that the virus was transmitted from pigs to monkeys without any direct contact between them. The researchers say they believe that limited airborne transmission might be contributing to the spread of the disease in some parts of Africa. They are concerned that pigs might be a natural host for the lethal infection.
Meanwhile passengers from suspect African cities are arriving on international flights, with minimal screening only for obvious symptoms, for a disease that is extremely contagious and that has an incubation period of up to 21 days.
It's a matter of time before it goes pandemic, if it hasn't already.
But even if the woman is truly negative, it's only a matter of time. There are now confirmed cases in Lagos, Nigeria and Morocco.
A mutated form of Ebola that could be transmitted by air would explain a lot. Like the fact that many of the healthcare workers in Liberia and other hot zones were contracting the disease even though they were wearing hazmat suits.
