It is announced that two types of 'new coronavirus' different from the new corona were transmitted from animals to humans

While the pandemic of the new coronavirus (SARS-CoV-2) has not converged, research results have been announced that two new types of coronavirus may be transmitted from animals to humans. The danger of a new pandemic has been pointed out because it seems that domestic animals close to humans, both dogs and pigs, became the source of infection.

New human coronavirus that originated in dogs identified

On May 20, 2021, Associate Professor Anastasia Brasova of the Ohio State University Faculty of Food, Agriculture and Environmental Sciences analyzed the viral genome of pneumonia that occurred in Malaysia from 2017 to 2018, and found that it was a canine-derived coronavirus. I found out that it was. ' This is the first time that a case has been reported in which the coronavirus acquired infectivity from dogs to humans.

Eight patients infected with this virus, named 'CCoV-HuPn-2018,' were all hospitalized for 4 to 6 days, received treatment such as oxygen inhalation, and then recovered and were discharged. The research team claims that the virus could be the eighth, as seven coronaviruses have been identified so far, including SARS-CoV-2, that infect humans.

'Of the eight patients infected with this new coronavirus, only one was an adult and the rest were children, so there is currently no evidence that the virus causes serious symptoms in adults. No, but we can't deny the possibility that this new coronavirus will eventually spread among humans. If that happens, the entire fight against the virus will go back to the beginning. '

When SARS-CoV-2 was first discovered, it was announced by WHO that it would not be transmitted from person to person, but it was later discovered that it would be transmitted from person to person.

In March 2021, a research team led by Professor John Rednicky of the University of Florida said, 'From three Haitian children diagnosed with fever between 2014 and 2015, a pig-derived deltacoronavirus (Hu) that infects humans. -PDCoV) was discovered. '

Delta coronavirus is a type of coronavirus that was once thought to infect only birds, but later turned out to infect pigs. In addition, this announcement suggests that pigs can infect humans.

'There is no evidence that Hu-PDCoV poses a major health threat at this time because all children in Haiti were mild, but in Haiti there are cases of SARS-CoV-2 infection,' the research team said in a treatise. It is worth noting that the severity of the new coronavirus infection (COVID-19) was less than expected, despite the high number. '' The results of this study show that delta-type coronavirus is transmitted from person to person. Not only has it revealed that it has the potential to acquire capacity, but also the role that infection with such viruses plays in the development of existing immunity to other coronaviruses such as SARS-CoV-2. It raises a debate. '
