The coronavirus pandemic continues to spread. Almost 19 million people have been infected with the virus in the world. The disease claimed the lives of 712 thousand patients. Bats are officially believed to have spread the virus. And this is one of those cases when a disease came to a person, as the scientists say, from the animal kingdom.
The researchers at the Center for the Study of Biodiversity and the Environment, Department of Genetics, Evolution and the Environment, University College London, believe that global changes that have upset the balance of wildlife communities in the environment are to blame.
It is known that representatives of the flora are able to carry dangerous pathogens and they are often found in those places where people are active. Humans have transformed over half of the planet's habitable land areas to meet their growing population needs. Forests, meadows and even deserts become zones for the construction of large cities.
As a result, many species of animals are shrinking, dying out, migrating to other territories, where they have to adapt to difficult conditions. As a rule, in most cases they are limited and lose to a person who continues to conquer new lands.
And only those species that are considered as numerous survive in this struggle. Such animals have a short and fast life, they develop in a variety of conditions and use all possible resources for that. Rodents and bats are universal examples. Omnivores are usually universal, and herbivores are also close to them.
But they are most often carriers of pathogens. And when humans transform their habitat into a place of their use, animals increase the risk of possible transmission of viruses to humans, which leads to outbreaks and epidemics.
Among those dangerous diseases that were transmitted to humans by animals, there were such dangerous viruses as COVID-19, severe acute respiratory syndrome SARS, Middle East respiratory syndrome MERS, human immunodeficiency virus, H1N1 flu, salmonellosis, plague, West Nile virus, rabies, and brucellosis.
