It is not easy for the virus to remain in the tissues of the species; These are adaptive processes that can take a long time, Daniel Martínez reported.
Dogs and cats are not carriers of the SARS-CoV-2 virus or of next reservoirs that will infect people, said the academic from the Universidad Autónoma Metropolitana (UAM), Daniel Martínez Gómez.
He explained that this is because it is not easy for the virus to remain in the tissues of the species, since it’s about adaptive processes which can take a long time.
He noted that in the course of normal contagion, the vector is recognizedIt is introduced into the cells and they identify the viral RNA to start replicating, assembling it in the correct way and distributing it in the tissues.
“So all of this must happen for a pet to become infectious,” he said in a statement.
In this regard, Martínez Gímez mentioned that as part of an experiment, Japanese scientists who infected ferrets and cats detected that viruses disappeared within a few days, although suddenly high viral loads appeared that immediately decreased almost completely. This revealed that they cannot affect humans.
“Now we have the second outbreak (of SARS), so the only thing that helps us understand is that there is a replica, but to be able to say that cats and dogs are going to be the next reservoirs that will contaminate people there are still many things to happen“He added.
In any case, said the academic, the job of doctors and veterinarians is to be on alert and epidemiological surveillance at all times, since “if they suddenly find many cases you have to investigate to go one step further and say with certainty if it is happening or not ”.
