A closer look at the Emergence, Persistence and Disappearance of Emerging Diseases, Epidemics and Pandemics and the destiny of COVID-19
Humans have been long exposed to various infectious agents and have struggled or avoided encountering these factors based on their knowledge, awareness and experience at different times, in order to keep and promote their health. Although humans have overcome these factors and thus survived, whenever they encounter a new pathogenic agent not fully acquainted with its epidemiological behaviors, they have surprisingly faced with these factors. Accordingly, they were forced to surrender to all the resulting epidemic and pandemics owing to the lack of sufficient knowledge to fight them. The same fact is being experienced in COVID-19 pandemic, and human beings realized the lack of awareness of the actions and reactions of emerging factors, even in this day and age. They also acknowledged that the fight against this emerging agent and its consequences would be based on the experience of previous emerging agent as well as scientific and technological advances, and that they would win the battle.
Here, we tried to investigate the casualties and correlations of the persistence and disappearance of emerging diseases, considering the experiences gained from the epidemiological behavior of emerging factors in the previous epidemics and pandemics. This goal has been followed in three consecutive sections: 1- Causes of emergence, 2- Stability and persistence and 3-The instability of many emerging diseases. We have concluded that the same is true for SARS, MERS, or coronaviruses that typically cause common cold.
And at this time human will come to believe that natural and intentional biological hazards have always lurked in human health! As a final word, the awareness and readiness of human beings, maintaining environmental health and respecting the biological rights of all human beings are the purely all factors that will reduce the damage is.
