Research on zoonoses

epidemiological threat

The face of the modern world is global anthropization, which affects the Earth’s resources and the stability of ecosystems. One of the consequences is the epidemiological threat resulting from the disclosure and then rapid spread of commonly unknown diseases. This applies to both animals and humans. It is estimated that about 70% of diseases affecting people are of zoonotic origin, they are the so-called zoonoses. The barrier of animal pathogen – human being is most often crossed by accident, in specific conditions of disturbance of the local ecological niche. Nevertheless, the consequences can be of epidemic proportions on a global scale. The classic examples are coronaviruses: a family of viruses that colonize vertebrates, often without any symptoms. In the beginning of 21st century, there were two epidemics in the world as a result of breaking the human-coronavirus barrier: MERS and SARS. The ongoing SARS-CoV-2 pandemic, causing the COVID-19 disease, is the third and the first of a global range to spread so rapidly, colonizing virtually all communities in the world in a few months.
