New data on the SARS-CoV-2 virus appears every day. On the one hand, all new information about the disease is good, because to defeat CoVID-19, scientists need to know as much as possible. On the other hand, some data cannot be considered good at all – for example, coronavirus mortality has increased to 5.5% worldwide, and intensive care units have both elderly and young people 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 has been infected by zoo staff who may have the disease without symptoms. Nadia was the first animal in the world with a confirmed diagnosis of CoVID-19, but it is also worrying that three tigers and three lions were also infected.
What happened to tigers and lions in the United States?
The news that a tigress in a zoo is said to have been infected by a person without the symptoms of CoVID-19 is reminiscent of the sixth episode of the first season of The Walking Dead, in which the protagonist tells the terrible truth of an epidemiologist at the center for Disease Control and Prevention (CDC). . It turns out that all people are already infected. It's just that some people only show symptoms after death. Perhaps this isn't the best comparison with CoVID-19 since the zombie doesn't exist, but the asymptomatic course of CoVID-19 in some patients still resembles a fictitious virus from the series.
According to NBC New York CoVID-19, not only was the 4-year-old Malayan tiger Nadia infected, but also three other tigers and three lions. I would like to remind you that due to the difficult epidemiological situation in the United States, all zoos were closed for visits on March 16 and the first symptoms in animals did not appear until March 27: All seven animals developed a dry cough and there was a decrease of appetite observed. As representatives of the zoo told NBC reporters, all the cats in the cat family otherwise feel good and can be dealt with with the help of a veterinarian. However, the test for coronavirus infection was only performed by the tigress Nadia. But does this mean that animals can be infected with CoVID-19?

Which animals get CoVID-19?
The question of whether pets are affected by the SARS CoV-2 coronavirus has been a concern of the researchers since it appeared in Wuhan, China, at the end of last year. So far, however, scientists have not been able to pinpoint the natural host of the coronavirus. The virus is thought to have originated from bats or pangolins – mammals that live in South Africa and are at risk of extinction due to poaching. Read more about how pangolines were suspected by scientists in our material. I would like to 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), which broke out in 2003 and killed 774 people. The total number of people infected was more than 8,000. At that time, bats proved to be the natural host of the coronavirus.
Last November, SARS-Cov-2 overcame the main barrier – we are talking about the transmission of the virus from animals to humans and the subsequent rapid transmission between humans. The world media used to write about a dog from Hong Kong whose test for coronavirus like that of its owner showed a positive result, but the amount of pathogens in the animal's body was extremely low. Afterwards, experts in Hong Kong concluded that domestic dogs and cats cannot transmit the virus to humans while they can become infected themselves.

However, the earth is full of rumors and at the end of March information appeared on social networks about people who put their pets to sleep because they fear they will infect them. However, there is no evidence that animals can spread the virus. The case of the tiger Nadia at the Bronx Zoo has shown that the animals themselves can be infected by humans, but they cannot infect us. Unfortunately, we ourselves pose a threat to pets. One of the first cases of CoVID-19 in Wuhan was a UK teacher telling his story after recovery. He said that his kitten also felt bad during the illness and then died. In contrast to this case, according to CGNT, there was one case in Hong Kong (China) – the test showed a positive result for the corona virus in a domestic cat. 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, CoVID-19 is being studied by scientists around the world. Some researchers are therefore trying to understand the susceptibility of various animal species to coronaviruses and determine how it spreads in the population. This has been reported on the website of the World Animal Health Organization, which is headquartered in Paris. However, there are still more questions than answers. Unfortunately, this insecurity causes panic – fake news and the lack of a huge amount of data about coronaviruses force people to do terrible things. According to an article published in The Bell, 5G cell towers have set fire to the UK. According to experts, this could lead to a decline in the infrastructure needed during a pandemic. It is surprising that some of us become CoVID-19 allies while sincerely believing that we are acting for the good of others.
I would like to remind you that at the time of writing this article, the coronavirus pandemic in the world has not yet peaked and most news from around the world is alarming. But no matter what the news is, you should never panic. You don't have to monitor the number of deaths, work or read your favorite book, watch a movie or a series every second. And don't put your pets to sleep – they can't harm you and infect you with the corona virus. On the contrary, your health is yours. So watch the self-isolation and communicate as little as possible with other people. Remember, the best thing you can do for yourself, your family, and your four-in-one is to follow the recommendations of the World Health Organization. The symptoms of CoVID-19 in humans have mild or moderate symptoms such as fever and cough that disappear within a few weeks. However, the elderly and people with weakened immune systems are at risk because they can have a serious illness. Health.
