When the whole world had learned the name of the new coronavirus, SARS-CoV-2, which the WHO named COVID-19, it has now been discovered in the United States a new strain that could also infect humans. It is called the swine acute diarrhea syndrome coronavirus or SADS-Cov, and since 2016 (which has been found out) it has been infecting pigs.
Experts from the University of North Carolina have carried out a long analysis of this virus, which also also comes from bats, just like the current coronavirus that is leading the global pandemic. And indeed the conclusion they have reached is that This coronavirus can also spread between humans.
To determine this, multitude of laboratory tests, finding that this coronavirus can affect human airways and intestinal cells, as the researchers have published in the journal ‘Proceedings of the National Academy of Sciences’.
What is this strain of coronavirus like?
Although it is true that it is within the same family of SARS-CoV-2, this particular virus is an alphacoronavirus, which causes gastrointestinal diseases in pigs. In the young or younger pigs, it translates into diarrhea, severe vomiting, or even death.
“Actually, alphacoronaviruses can be equally prominent, if not greater, concerns for human health, given their potential to jump rapidly between species”Says Ralph Baric, one of the researchers.
The tests carried out
To see what its transmission between species was like, American experts tested various types of cells, infecting them with a synthetic form of the swine diarrhea syndrome coronavirus.
The study carried out indicates that many mammalian cells can become infected, what happens that this coronavirus affects more intestinal cells and the one that is causing thousands of deaths worldwide attacks the lung cells the most.
In any case, viruses in different animal species are there and they must not be neglected. In fact, It is not the first time that a threat has been found in pigs, since in summer it was discovered a flu also in these animals with features similar to the swine flu 1918 and 2019. A strain called G4 EA H1N1.
