![]() Higher temperatures are capable of inducing inactivating mutations to some key viral pathogenic proteins. This report goes in agreement with Martínez-Sobrido et al., who proved that temperatures not only influence the viral capacity to spread but also affect viral pathogenesis. proved to decrease deaths from COVID-19, this might be via attenuation of viral virulence. Temperatures have been postulated as a key player in such discrepancy, as well as humidity which Ma et al. Two smaller outbreaks caused by the coronavirus (CoV) occurred earlier during this century, namely severe acute respiratory syndrome (SARS-1) and Middle East respiratory syndrome.Įxamination of the death rates across the globe clearly shows unclear discrepancies between the northern and southern hemispheres. On 22 March, COVID-19 was confirmed as a pandemic by the WHO. ![]() The first case can be tracked to 17 November 2019. Obesity also increases cardiovascular and respiratory morbidities, which are coupled to increased ICU demand and deaths among infected cases.Ĭoronavirus disease 2019 (COVID-19) started as a small outbreak in the city of Wuhan, China. Such predisposing factors might operate by upregulating the inflammation pathway in heavily struck countries, leading to easier triggering of the infamous cytokine storm syndrome. This article shows a tight correlation between average BMI, food supply per country, and COVID-19-related deaths. ![]() ResultsīMI per country proved to be the second best predictor of death rate with an R value of 0.43, and GDP being the best predictor with R = 0.65. This is a retrospective study in which the rate of COVID-19 deaths was correlated with each of the following independent variables: total tests per 1 million population, gross domestic product (GDP), average temperatures per country, ultraviolet index, median age, average BMI per country, food supply, Bacille Calmette-Guerin compulsory status, and passenger traffic. The main goal of our series is to determine the best predictors of such discrepancy. Visual examination of the world map shows a wide variation of death tolls between countries. Coronavirus disease 2019 (COVID-19) is the largest outbreak to strike the world since the Spanish flu in 1918. ![]()
