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 31st 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 data of infected cases and deaths 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. Most of the cases are observed in the temperature range of 40°F
to 60°F. Also, we analyzed the dependence of 2019-nCoV transmission and death cases on life expectancy.
Most of the cases related to COVID-19 in the entire world were adult and old patients.
The global connectivity between China as a “Manufacturing Hub” and other counties also plays a
vital role in the transmission of COVID-19.
Conclusion: The spread pattern of COVID-19 cases is in good agreement with our study, but this
does not mean that it will not spread in warm areas. The precautionary measure provided by WHO
and health departments of various countries should be followed to slow down the transmission rate
