|The infection is thought to get into humans through close contact with bodily fluids.|
Now, researchers from the Canadian Food Inspection Agency and the country's Public Health Agency have shown that pigs infected with this form of Ebola can pass the disease on to macaques without any direct contact between the species. In their experiments, the pigs carrying the virus were housed in pens with the monkeys in close proximity but separated by a wire barrier. After eight days, some of the macaques were showing clinical signs typical of ebola and were euthanised. One possibility is that the monkeys became infected by inhaling large aerosol droplets produced from the respiratory tracts of the pigs. One of the scientists involved is Dr Gary Kobinger from the National Microbiology Laboratory at the Public Health Agency of Canada. He told BBC News this was the most likely route of the infection. "What we suspect is happening is large droplets - they can stay in the air, but not long, they don't go far," he explained. "But they can be absorbed in the airway and this is how the infection starts, and this is what we think, because we saw a lot of evidence in the lungs of the non-human primates that the virus got in that way." - BBC.
