The world has not witnessed in history a global epidemic that this new Covid19 epidemic rapidly spread, although its risks are less than many previous epidemics such as plague, cholera, syphilis and smallpox that killed hundreds of millions of the world's population within years, and despite the death rates of this epidemic since the beginning of its outbreak until now, it has not exceeded death rates from human diseases such as heart attacks, car accidents, malaria, cancer, etc., it is still much lower than them. But this epidemic comes to upset health standards and capacity in the most developed countries in the world and to destroy their health systems.
This paper aims to study the most geographical and environmental factors influencing the occurrence of this epidemic, that includes disease pattern, disease ecology. Weather conditions, like temperature, humidity, and winds. Topographic characteristics. Blood types. Races, ethnicities. Ethics and behavior. Morbidity, recovery and fatality rates. These dimensions and factors help to draw a realistic picture of the map of the disease in the world.
