Emerging viral diseases encompass two types, those of new appearance in the population and those that we previously knew about or re-emerging, but that at a certain moment present an exponential increase in incidence or geographic distribution in the form of epidemics or outbreaks. These emerging and re-emerging viruses share a series of characteristics that establish the emerging virus model, such as having an RNA genome, being zoonotic, transmitted by vectors and transmissible to humans, that the virus is able to recognize and provoke a response in receptors. Conserved in several species and inhabiting ecosystems that undergo ecological, demographic or social changes that favor the spread of the virus. There are different factors that contribute to facilitating the emergence of viral infections, although this is made up of three fundamental aspects such as the susceptible population, the virus itself and the environment where both can interact.
