Bats become mobile virus seeders for flight
Although the increase in body temperature can make the bat’s metabolism faster, it will cause damage to the bat’s body, and it is reasonable to say that the bat’s life span will be shortened.
However, bats live very long, and some bats can live up to 40 years.
The cause of longevity may be that the bat’s body has evolved a self-healing function (the conclusion is a hypothesis). For example, the cells of our human body will age and die after 50 differentiations, which will cause human aging and death. However, once the bat’s somatic cells are damaged, the cells will be repaired in time, so the life span of the bat is much higher than the theoretical value.
And all this can make them infected with the virus, they will not get sick, but will “harmoniously get along with” the virus.
Scientists have collected more than 4,100 viruses from bats around the world, including rabies virus, sars virus, and the natural host of Ebola’s disease sentences.
The reason why bats are called “virus seeders” is because bats are social animals, and there are even tens of millions of bats in a large bat cave. These bats can “exchange” the virus to each other during the socialization process. That is to say, originally one bat carried the virus, and after a few days of getting along, tens of millions of bats may be infected.
Second, when bats communicate with each other, in addition to exchanging feelings, they also exchange viruses that they carry with each other, which causes the same bat to carry multiple viruses.
Furthermore, bats have a flight function. Many types of bats migrate seasonally in search of food. For example, Mexican tailless bats fly at least 800 miles in summer caves and wintering sites.
In addition, bats are widely distributed, with many species and the second largest number of mammals.
All these characteristics allow bats to spread the virus they carry around the world. The virus will be transmitted to humans through intermediate hosts such as civet, camel, and various game products.
However, although bats are poisonous, they generally live in quieter areas, and to avoid competing with birds, bats choose to travel at night. It hardly overlaps with the area of human life, so in the natural environment, viruses carried by bats are difficult to infect humans.
However, the emergence of game has given the bat virus an additional way to reach humans. The Ebola virus in Africa and the epidemic 17 years ago were transmitted to humans through game.
So, in order to prevent the virus from re-emerging next time, all we can do is to reject wildlife and refuse food of unknown origin.
