The 2019 novel Coronavirus in China has now reached various countries in the world, and scientists are desperately trying to find out how it has finally reached humans.
And now a new study has identified bats as potential hosts with new clues about the source of this virus.
Researchers analyzed 10 genome sequences of the 2019 novel coronavirus, obtained from 9 patients infected with this virus in Wuhan, in a research published by China Dong First Medical University in the medical journal Lancet.
They discovered that all genome sequences are highly matched and that they had the same genetic sequencing rate of 99.98%.
This, in turn, indicates that the virus has recently 'transmitted' to humans because if the transition had taken place a long time ago, there would have been a significant difference in virus sequences, as the viruses change and spread very rapidly.
Professor Wai Feng Shui, who is on the research team, said, "It was shocking that the sequences of the virus were almost identical in different patients, indicating that the source of the 2019 novel coronavirus transmission was the same source, And it happened in a very short period of time and it was diagnosed very quickly. '
The virus came out in late December and in a short time, it has reached 20 countries, including China, affecting more than 8,000 people and 171 deaths.
Most of the early cases came from people who worked or went to Wuhan's Huanan Seafood Market (where various types of animals are sold).
To find out the cause of this virus, researchers compared its genetic sequence to the library of viral sequences and discovered that it was the closest to the 2 corona-infected bats.
88% of these two coronaviruses share genetic sequences with the 2019 novel coronavirus.
Based on these results, the researchers said that the source of the virus was bats, but bats were not sold in this food market, which suggests that it was discovered by another animal (which has not yet been identified) in humans. Worked like a staircase for the transfer.
"It looks like another animal probably served as a temporary host for the bats and its transfer between humans," said Nguyen Wu, who is involved in the research.
Researchers say that overall, the spread of the virus once again increases the risk of transmitting the virus and its human population to wildlife.
Earlier, a study said that snakes sold in this food market caused the spread of the virus, but some experts criticized the study, saying it was not clear until now that the coronavirus had caused the snakes.
