Tropical Conditions and Outbreak of COVID-۱۹

Background: The new novel Coronavirus ۲۰۱۹ (nCOV-۱۹ or COVID-۱۹) has caused an unprecedented pandemic in humans. All nations have heightened their surveillances after the quick diagnosis of potential cases of the COVID-۱۹.  Objectives: Recent statistics have mentioned that virus outbreak in tropical countries is relatively low compared to cold nations. To support this conclusion, we considered the six main tropical regions to investigate the pandemic distribution at the initial phase.  Methods: Chi-square test was applied to understand the correlation between outbreak and temperature changes. Significant probability P-value was set to P<۰.۰۱. P-values were calculated to both positive and death cases.  Results: Out of ۱۲۱۱۵۶۲ infected cases, ۴۱۷۷۶ cases (۳.۴۵%) were registered at high-temperature countries (P<۰.۰۰۰۱) and ۱۱۶۱۷۸۶ cases (۹۶.۵۵%) at other countries like European countries or the USA. Moreover, only ۱۴۳۳ mortality cases (۲.۲%) happened, and the remaining ۹۷.۸% of mortality happened among other nations. Conclusion: Similar to other respiratory viruses like flu and influenza, there is a low outbreak of COVID-۱۹ in tropical nations compared to the other countries. Apart from weather conditions, it is also recommended to follow the serious preventive measures imposed by governments to survive this novel epidemic.
