One health: economic and social analysis of Covid-19 worldwide
Mourad Zeghdoudi, Mardja Tahri.
Abstract
In veterinary medicine, there is an analogy between epidemiological characteristics of emerging and re-emerging animal viral diseases (ex: avian infectious laryngotracheitis) and the Covid-19. These characteristics are represented by occurring and re-occurring of these diseases, cyclical emerging at intervals around 6 to 7 years and cross-border transmission (pandemic) by all mode of transmission. In addition, these pathologies were manifested by their spontaneous disappearance after an evolution of a few months probably due to the progressive loss of their virulence and to a regressive viral pressure. The evolution of these pathologies with moderate mortality rates depends on the health barriers put in place around the disease outbreaks. The most serious cases of these emerging diseases are found in regions of high density of flocks and inefficient biosecurity.
Key words: One health, Economic, Social analysis, Covid-19
