In the United States, a tigress discovered a coronavirus. What is this talking about?

Every day new virus data appearsSARS-CoV-2. On the one hand, any new information about the disease is good, because in order to defeat CoVID-19, scientists need to know as much as possible. On the other hand, some data cannot be called good at all - for example, mortality from coronavirus worldwide has increased to 5.5%, and in the intensive care wards, both elderly and young people are in serious condition. Another unpleasant news was the news of a tigress named Nadia from a zoo in the Bronx, New York, in which a test for coronavirus gave a positive result. Researchers believe that Nadia was infected by zoo employees who could have the disease without symptoms. Nadia became the first animal with a confirmed diagnosis of CoVID-19 in the worldbut it is also worrying that three tigers and three lions were also infected.

What happened to tigers and lions in the USA?

The news that the tigress in the zooallegedly infected by a person without the symptoms of CoVID-19, involuntarily brings back memories of the sixth episode of the first season of the series The Walking Dead, in which the protagonist learns the terrible truth from an epidemiologist from the Center for Disease Control and Prevention (CDC). It turns out that all people are already infected, it’s just that some people will only show symptoms after death. Perhaps this is not the best comparison with CoVID-19, since the zombie does not exist, but the asymptomatic course of CoVID-19 in some patients still resembles a fictional virus from the series.

According to NBC New York, CoVID-19 is not infectedonly the 4-year-old Malay tiger Nadia, but also three other tigers and three lions. Let me remind you that due to the difficult epidemiological situation in the USA, all zoos were closed for visits on March 16, and the first symptoms in animals appeared only on the 27th: all seven animals developed a dry cough and a decrease in appetite was observed. As representatives of the zoo told NBC reporters, otherwise all the animals of the cat family feel well and cope with the infection with the help of a veterinarian. However, the test for coronavirus infection was carried out only by the tigress Nadia. But does this mean that any animals can become infected with CoVID-19?

What animals get CoVID-19?

The question is whether pets are sickSARS-CoV-2 coronavirus has been bothering researchers since its appearance in Wuhan, China, at the end of last year. However, until now, scientists have not been able to accurately establish the natural host of the coronavirus. Presumably the virus came from bats either pangolins - mammals that live in South Africa andare on the verge of extinction due to poaching. Read more about how pangolins were suspected by scientists, read in our material. Let me remind you that the genome of the SARS-CoV-2 virus is 70% similar to the genome of the SARS virus (severe acute respiratory syndrome), an outbreak of which occurred in 2003 and claimed the lives of 774 people, and the total number of infected was more than 8 thousand. Natural host of coronavirus at that time turned out to be bats.

Back in November last year, SARS-Cov-2 overcamethe main barrier is the transmission of the virus from animal to human and its subsequent rapid transmission between people. Earlier, the world media wrote about a Hong Kong dog, whose test for coronavirus showed a positive result, like that of its owner, but the amount of pathogen in the animal’s body was extremely low. After that, experts in Hong Kong came to the conclusion that domestic dogs and cats cannot transmit the virus to people, while they themselves can be infected. Read more about cases of infection of domestic animals in an article by my colleague Daria Yeletskaya.

However, the Earth is full of rumors and at the end of March in social networks began to appear information about people who put their pets to sleep because of the fear of getting infected from them. but there is no evidence that animals can spread the virus. The Case of the Tiger Nadia at the Bronx Zooshowed that the animals themselves can be infected by humans, but they cannot infect us. Unfortunately, we ourselves pose a threat to pets. So, one of the first cases of CoVID-19 in Wuhan was a teacher from the UK, who shared his story after recovery. He said that during the illness, his kitten also felt bad, and then died. In contrast to this case, according to CGNT, there was a case in Hong Kong (China) - in a domestic cat, the test showed a positive result for coronavirus. It is noteworthy that no symptoms are observed in the animal - at the time of writing, the cat is in quarantine under the supervision of veterinarians.

Today, the study of CoVID-19 scientistsall over the world. So, some researchers are trying to understand the susceptibility of various animal species to coronavirus and determine how it spreads in the population. This was reported on the website of the World Organization for Animal Health, whose headquarters is located in Paris. However, there are still more questions than answers. Unfortunately, such uncertainty is causing panic - fake news, along with the lack of a massive amount of data on coronavirus, are pushing people into terrible things.

According to an article published in The Bell, inBritain's people began to set fire to 5G cell towers. According to experts, this could lead to a drop in infrastructure needed during a pandemic. It is surprising that some of us become allies of CoVID-19, while sincerely believing that we act for the good of others.

Let me remind you that the coronavirus pandemic in the world onthe moment of writing this article has not reached its peak, and most of the news that comes from around the world is alarming. But no matter what the news is, you should never panic. You do not need to monitor the number of deaths every second, do work or read your favorite book, watch a movie or series. AND do not put your pets to sleep - they cannot harm you and infect youcoronavirus. On the contrary, their health is up to you. So observe self-isolation and communicate with other people as little as possible. Remember, the best you can do for yourself, your family and your four-in-one is to follow the recommendations of the World Health Organization. As for the symptoms of CoVID-19 in humans, most face mild or moderate symptoms, such as fever and cough, which go away within a few weeks. However, older people and people with weakened immune systems are at risk, since they can have a serious illness. Be healthy.
