Corona and Misery: Sixth Epidemiologic Transition by COVID-19 and Its Consequent Cardiovascular Complications

A theory of the epidemiology of population change was first raised  by Abdel R. Omran in 1971 (1-3) and it had originated from the demographic transition model (4,5). Before that, it was suggested other disciplines like fertility, mortality, and migration are influencing factors for population change (6). But progression in science particularly health and deep recognition of diseases demonstrated that epidemiology is remarkably influenced by distribution of disease and death also their outcomes in population groups (1,7,8).
