Researchers at the Wuhan Institute of Virology, China, have identified a new coreronwirus in bats that uses the same entry tract in cells as a virus responsible for Covid -19. The virus has not been found in humans and was found only in a laboratory. Discovery news on Friday raised the stock prices of some vaccine manufacturers.

Scientists in the journal cell cited by News Ageni Reuters said that the virus, known as HKU5-Cov-2, does not easily enter human cells as Sars-Cov-2 and “human population” The risk of emergence in should “be exaggerated”.
What is the new bat virus and how does it spread?
The HKU5-Cov-2 covid-19 as well as the virus shares similarities with the virus that causes the Middle East respiratory syndrome (Mers) because they all originate from the HKU5 coronvirus.

Researchers stated that like Sars-Cov-2, the new virus also has a feature known as a furine cleavage site that helps it to enter cells through Ace2 receptor protein on cell surfaces.
In laboratory experiments, HKU5-COV-2 tests infect human cells with high Ace2 levels in tubes and high Ace2 levels in human intestines and airways models.

Although the virus has spread among the bats, researchers are still uncertain about the potential risk of the animal-human transmission of the virus. Each coronvirus cannot infect humans, as a large family of Koronwirus virus that can cause diseases up to normal cold to severe acute respiratory syndrome (SARS) and Koronwirus disease -2019 (Kovid -19).
Michael Oosterhom, an infectious pathologist at the University of Minsota, told Reuters that the response to the study on HKU5-Cov-2 was overblown.
Are there any symptoms for viruses?
Symptoms shared by the HKU5 category of coronwirus and Mers are fever, cough, fatigue, congestion, sneezing, chills, loss of appetite, shortness of breath, diarrhea and vomiting.
What to do to stop the virus?
While the virus has not yet been proved to infect humans, the disease control centers suggests that one should always be up -to -date with vaccination, use precautions to prevent spreading spread hands thoroughly , Masks and tests for any other comorid risks.
