New one Corona virus Discovered in China There is only a small step and by creating another global epidemic, experts have warned.
Scientists believe that HKU5-Cov-2, a version, can infect a wide range of boundaries. Animal instead Covid-19 , Which caused millions of deaths – And there may be more likely to jump between the species.
American researchers are afraid that HKU5-Cov-2 found in China in February may also infect humans, leading to widespread outbreaks.
New study, published Nature communicationA low-colored group of coreonwirus was seen, called Merbecovirus, including HKU5 and Mers-Cov, which is responsible for the malignant Middle East respiratory syndrome.
The Washington State University team noticed how the new pathogen interacts with human cells.
They found that a small change in the spike protein of the virus may allow it to attach human Ace2 cells into people’s throat, mouth and nose.
HKU5-Cov-2 can infect and replicate inside human cells in both airways and intestines.
According to the World Health Organization, about 35 percent of the people were infected Middle East respiratory syndrome Die. Since 2012, some 27 countries have reported cases, causing 858 known deaths due to infection, which spread from camels.
But when the HKU5 was discovered in February, scientists warned against exaggerating the risks as it does not easily enter human cells. Sars-Done-2Which caused Kovid -19.
HKU5 was first detected Bat Where something says by scientists of Chinese laboratory, Kovid originated in 2019.
Professor Michael Letco, a virologist who resorted to the study, said: “HKU5 Virus Especially not actually noticed, but our studies show how these viruses infect cells.
“What we got is also the HKU5 virus, can only be a small step that can be overcome by being able to spread to humans.”
When Kovid -19 emerged, it was widely convicted on markets in China Different breeds of wild animals Closed and often murdered close to other animals. The meat is sold at open-air stalls.
Critics said that there were markets The correct breeding ground for new zoonotic diseases – Those who spread to humans – to emerge.
Scientists, whose experiments studied how new pathogens interact with human cells, believe that the virus would have to do something if it was to infect humans.
“These viruses are closely related to Mers, so we have to be worried if they ever infect humans,” said Pro Letco.
“While there is no evidence that they have crossed people so far, have capacity and it makes them worth seeing.”
