Abstract

The viruses coexist for approx. 300 million years with the humans. Sometimes viruses can infect people on a large scale. But how was the current pandemic possible? Global warming is causing extreme weather events that have led to an increase in infectious diseases. The new climate can support epidemiological vectors for longer periods of time, creating more favorable conditions for replication and the emergence of new vectors. In the case of emerging infectious diseases, it is considered that there is a border that has already been crossed. Viruses normally have a native area (their "reservoir") from which they should not be pushed out. This creates a dangerous intimacy, with "hotspots" that include locations such as markets, which become real hotbeds of epidemics. DOI: 10.13140/RG.2.2.26974.87364
