Dogs can carry a new virus that is potentially deadly to humans



YOUA new mutation of influenza A virus can be transmitted from dogs and cats to humans, a study conducted for 10 years by Dae-sub Song, a professor at the University of Korea, reports Phys.org.

It was previously discovered that the canines can be hosts of the H3N2 subtype, in this case known as & # 39; dog influenza virus & # 39; (CIV, for the acronym in English). The H1N1 strain also affected dogs during the swine flu pandemic. According to Song, the two subtypes can work together and produce a new variation, & # 39; CIVmv & # 39; called.

The study found that CIVmv host dogs can infect ferrets – used in experiments as substitutes for humans – whose virus protection mechanisms are similar to those of humans: therefore the virus can also be believed to threaten our species.

The danger lies in the lack of immunity to the new species, Song explains. Despite trying to develop a vaccine, the task is complicated by the intensity of the CIVmv mutation.

In the meantime, the high virus contamination capacity has already been demonstrated. In one case, examined by the Korean scientist, it was transferred to the cats of a shelter, where 100% of the animals were infected and 40% died.

CIVmv can become an endemic virus in pets closest to humans, Song warns. The other threat lies in the ability to evolve. "Pre-existing VSDs can recombine or regroup with human influenza viruses and give rise to new viruses that in turn can lead to unique pandemics," the researcher said.

The full results of the research will be presented at the annual conference of the Society of Microbiology in Belfast (United Kingdom) on April 10.
