WHO will investigate coronary infection between humans and pets
Cats may be infected with the new strain of coronavirus, but dogs, ducks, pigs and chickens do not seem to be susceptible to this pathogen, a study published in Science.
According to Reuters news agency, research just published in the journal Science said that in addition to cats, mink can also be infected with SARS-CoV-2. However, other animals such as dogs, chickens, pigs and ducks are not infected with this virus.
The study published in Science aims to find out which animals are most likely to infect the latest strain of corona virus. From there it is expected to be used as a test subject to potential vaccines against COVID-19.
This study was conducted in China in January and February of this year. The team found that cats and ferrets are the species most at risk of acquiring the new strain of coronavirus after they deliberately expose them to infected particles through the nose.
They also found that cats can infect each other through droplets of respiratory fluid. Affected cats have viruses in their mouths, noses, and small intestines.
The cats exposed to the virus were severely damaged in the lungs, nose and throat. In ferrets, although new strains of corona virus have emerged in the upper respiratory tract of animals, they do not cause serious illness in them.
“The monitoring of SARS-CoV-2 infection in cats should be seen as an addition to the elimination of the human COVID-19 disease,” the study authors wrote.
So far it is believed that SARS-CoV-2 has been transmitted from bat to human. With the exception of some cat and dog infections, there is no conclusive evidence that domestic pets can be vectors.
In the aforementioned study, antibody tests showed that dogs were least likely to be infected with corona virus, while pigs, chickens and ducks were not infected with this strain.
Recently, a tiger at the Bronx Zoo showed a dry cough and stopped eating after contacting a zoo employee who was positive for corona virus.
The World Health Organization (WHO) on April 8 said it was working with partners to further study the role of pets in the current disease crisis.
Based on the evidence up to date, WHO epidemiologist Maria Van Kerkhove told a news conference: “We do not believe they play a role in infection but we think that they can be infected by carriers. “
Meanwhile, WHO emergency program expert, Mike Ryan, urged people not to be cruel to animals because of the disease. “They are as victims as we all are,” said Mike Ryan.
