Background: Today, the world is facing COVID-19 mutant which was declared as a pandemic disease by the
World Health Organization. COVID- 19 has spread rapidly to 203 countries and up to 31 March 2020, 36405 people had
lost their lives. We aimed to study the impact of three parameters i.e. weather, life expectancy, and travel either due to tourism or business purposes on the transmission of the COVID-19.
Methods: The infected cases and death data of different countries and territories related to the 2019-nCoV are studied. These data are collected from the situation reports issued by WHO.
Results: The Temperature- Time trajectory shows that the dissemination of Coronavirus has a high tendency in cold climate
countries. The maximum number of cases are being observed within a temperature range of 40°F to 60°F. Also, we analyze
the dependence of 2019-nCoV transmission and death cases on life expectancy. Most of the informed cases related to
COVID-19 in the whole of the world were adult and old patients. The global connectivity between China as “Manufacturing
Hub” and other counties also plays a vital role in the transmission of COVID-19.
Conclusions: The spread pattern of COVID-19 cases is in good agreement with our study, but it does not mean that it would
not spread in warm regions. The precautionary measure provided by WHO and various countries health departments should
be followed to slow down the transmission of COVID-19.
