📰 The planet of pandemics

If climate change leads to migrations of animal populations, it means that it increases the risks of viruses being exchanged between different species. And what about us?

Keep in mind that the vast majority of virus (A virus is a biological entity that needs a host cell to use it…) are exclusive to a species (In the life sciences, the species (from Latin species, “kind”…). But with that Number (The size is a generic term in metrology (account, amount; a scalar,…) of circulating viruses this has left one through all epochs Number (The concept of number in linguistics is dealt with in the article “Number…”.) raised, at conicidence (In colloquial language the word chance is used to express a lack of efficiency, otherwise…) has become transmissible in another way due to a mutation. And sometimes to us. The learned name is zoonosis (A zoonosis (from Greek zôon, “animal” and nosos,…): a infectious disease (An infectious disease is a disease caused by the transmission of a…) what went from one animal (According to the classical classification, an animal (from the Latin animus, spirit or life principle) is a…) to human. That Pandemic (A pandemic (from Ancient Greek πᾶν / pãn (all) and…) of COVID-19 is a zoonosis, although we are not yet sure about the animal of origin.

By changing from Area (The notion of territory has gained increasing importance in geography, and in particular in ….)so an animal can cross street (The word “road” derives from the Latin (via) rupta, literally “way…”) an animal he had never met before. Does this increase the risk of cross-species transmission of disease? Yes, answer researchers who have built one mathematical model (A mathematical model is a translation of reality to apply the tools to it…) of 3,139 species of mammals and the 40,000 previously known viruses from which they are derived the hosts (The Hostess is a science fiction short story by Isaac Asimov, published for the…), as well as their current and likely movements over the next 50 years. Their conclusion is that over the next 50 years we can predict 4500 cases in which a virus or even several viruses could “jump” from one species to another. The article appeared in the magazine on April 28 Nature.

So far, the biologists who have dealt with this question have been more concerned with one virus after the other: will it survive this or that environmental change, does it have mutations that can enable it to “jump” to another species.

However, because of the size of the problem—those 4500 possibilities—a signal (General terms A signal is a simplified and generally encoded message. There are…) alert for people. When the researchers examined where these problematic species would have migrated in 50 years, they found that the vast majority were areas where our cities are expanding. For example, note in the New York Times Pathology-ecologist Gregory Albery, co-author of the study, could transmit its virus to a raccoon that lives comfortably in urban areas from a small rodent that had previously had little contact with humans.

In fact, it has already started, as the numbers for last century (A century is now a period of one hundred years. The word comes from the Latin saeculum, i, what…) show that 60% of the new epidemics that have hit us are zoonoses. The likely result of unprecedented 20th-century contacts between humans and certain animal species, such as batsAsia (Asia is one of the five continents or part of the supercontinents Eurasia or Afro-Eurasia of…) from South East (Southeast is the direction midway between the southern and eastern cardinal points. Southeast is…).

Incidentally, the researchers note that there are concerns about the impact of these new viruses on humans, but it should be remembered that for an already weak animal population, there is a new virus to fight against immune system (An organism’s immune system is a coordinated set of elements of…) unprepared can have devastating effects.

that journalist (Journalist is a person whose professional activity is journalism. We’re talking…) Ed Yong uses the word “pandemicene” – we would have entered a “pandemic era” in which large numbers of new hosts are carrying old viruses and maybe even new ones. That location (In geography, situation is a spatial concept that allows for the relative location of a….) was created by the collision (A collision is a direct impact between two objects. Such an impact transfers part of…) between two of the human impacts on nature: climate change and loss of wildlife habitat. And this situation, Yong concludes, lies at the intersection of three of our existential fears: “Climate change, pandemics, and WW6.” die out (In general, the word obliterate refers to an action consisting of obliterating something…) from Dimensions (The term mass is used to denote two quantities attached to one…)” of life (Life is the given name 🙂 At Earth (Earth is the third planet in the solar system in order of distance…). “These three fears are actually the same mega-problem.” As we emerge from one pandemic, he warns, we should do well not to underestimate the importance of being better prepared for the next…
