This is the conclusion reached by American and British scientists from 11 different institutions. They studied the health status of deer in the forests and zoos of Iowa (USA).
“PCR-testing, carried out between April 2020 and January 2021, showed that one third of the deer had traces of SARS-CoV-2 in the lymph nodes”, - Rossiyskaya Gazeta notes.
Researchers believe that the virus can mutate if it is kept inside the deer population for a long time. Thus, deer risk becoming super-distributors of covid, capable of retaining particles of a dangerous infection in their bodies and, under favorable circumstances, transmitting them to others.
Scientists are convinced that deer are spreading the virus among themselves. However, some individuals became infected with covid after contact with humans in the zoo or with other animals.
According to experts, covid can be transmitted from humans to animals and from some mammals to others. In this case, the symptoms of the disease appear in all the same.
Minks, macaques, cats and ferrets were found to be most susceptible to covid in the laboratory. Meanwhile, pigs and dogs were immune to covid.
Earlier in Norway, the country's authorities destroyed the entire population of minks, fearing that from them the covid would be transmitted to humans. After a successful campaign to vaccinate the population, restrictive measures for residents of the Scandinavian countries began to be lifted. In particular, the Danish authorities, where about 80% of residents are vaccinated, stopped considering covid a serious threat to society.
