According tomedia reports, the current new crown epidemic is still raging around the world. Many people are still sick, or will be sick in the weeks or months to come, and vaccines may be the only way to really fight it. Now new research suggests that humans are not the only species infected with the virus. Months of research have been conducted on the response of dogs and cats to the virus, which also appears to be infected, but cats have a special defense mechanism that may eventually prove useful to humans.
The study, published in Proceedings of The National Academy of Sciences, showed that while cats and dogs may be infected with the virus, they do not exhibit symptoms and are largely unsymlocated by the virus, especially cats, which appear to be much more resistant to the virus than initially thought.
In the experiment, the cat was deliberately infected with the new coronavirus and then in close contact with other cats. The dog took the same action. In the end, it’s good news that dogs don’t show any ability to spread the virus to each other. At the same time, although cats transmit the virus to other cats, things have a twist.
It’s worth noting that while cats infected in the lab are highly contagious and release active viruses, they can build strong defenses against re-infection. Cats carrying the virus develop immunity that is far stronger than that of other species observed in the laboratory environment.
Unfortunately, however, there is a problem here. Because of the length of the test, no one knows how long the cat can maintain strong immunity. Is this a fleeting phenomenon or is a virus-infected cat permanently protected from re-infection? We don’t know yet, but the strength of the immune system’s response to the virus after infection suggests that they may be a good target for vaccine-related research.
