This is the reason for the outbreak of the Corona epidemic .. and bats reveal the mystery

Finally, after a long wait, a team of scientists from the United Kingdom, Germany and the United States came to know the cause of the outbreak of the new Corona virus, in China, which was behind bats.

According to the results of the scientific team's research, the mechanisms of environmental change in southern China and the surrounding areas led to a sharp increase in the diversity of bat species, which was described as the cause of the epidemic.

Scientists have found that global climate change, rising temperatures, and an increase in sunlight and carbon dioxide in the atmosphere have altered the composition of vegetation and the natural habitats of animals in many regions of the world.

In turn, a large-scale ecological study in southern China and the surrounding areas in Myanmar and Laos revealed significant changes in the type of vegetation in these areas over the past century, creating a favorable environment for bats to live there.

As is known, the number of new viruses that arise in bat populations directly depends on the number of local species of these animals.

Scientists estimate that 40 species new Of the bats that have appeared in Wuhan alone since the beginning of the twentieth century, and are likely to bring with them about 100 types of corona viruses, due to global warming and the associated rapid growth of rainforests, the region has become, according to the researchers, a “global hotspot” for the emergence of animal pathogens new origin.

In the context also, the first author of the study, Dr. Robert Bayer, from the Department of Zoology, explained in a press release at the University of Cambridge, that climate change during the past century has made conditions in the southern Chinese province of Wuhan suitable for more species of bats.

He also pointed out that, because the climate is not good, many species have moved to other places, carrying their viruses with them. Interactions between animals and viruses in new local systems have given rise to a large number of new harmful viruses.

Corona mutated?

Based on data on temperature, precipitation, and cloud cover over the past XNUMX years, the authors compile a map of the world's vegetation cover as it was a century ago, and then use information on the vegetation requirements of different species of bats to determine the global distribution of each species in the early part of the century. Comparing this picture with the current distribution allowed scientists to see how the diversity of bat species around the world has changed over the past century.

According to scientists, there are currently about 3000 types of coronaviruses. Each species of these animals carries an average of 2.7 coronaviruses. Most coronaviruses transmitted by bats are not transmitted to humans.

Corona spread and others

However, the increase in the number of bat species in a given area increases the likelihood that pathogens dangerous to humans will appear there.

In addition, the study found that over the past century, climate change has also led to an increase in bat species in central Africa and parts of Central and South America.

It is noteworthy that the origin of the new Corona virus and its relationship to bats is still a mystery that baffles scientists, despite the fact that many months have passed since its appearance.
