While the data so far has shown conflicting evidence about the impact of atmospheric temperatures on the spread of the coronavirus, a new Greek study appears to show that transmission of the virus in countries with high temperatures is indeed lower.
The study, which is being conducted by the Pulmonary Clinic of the University of Thessaly, has pulmonologist Prof. Konstantinos Gourgoulianis as coordinator and Dr. Ourania Kotsiou as a lead researcher. They are working in collaboration with the Metsovo Center for Interdisciplinary Research of the National Technical University of Athens and the Department of Business Administration of the University of Patras.
The researchers found a clear impact of atmospheric temperature on the rate of the spread of the disease.
Countries with lower temperatures — and particularly with average temperatures of 0-18°C — have an increased rate of new cases of COVID-19 per day, and a higher total number of confirmed cases compared to countries with higher average temperatures.
The Greek researchers also suggest that the effect of temperature appears to be independent of the time of the first outbreak or the population density of each country.
Of course, the scientists noted that the final number of outbreaks depends significantly on the measures taken to prevent the spread of the virus in each of the countries involved, as well as the country’s recording systems, which must also be taken into account.
Many studies, according to the professor, suggest that the cold favors the survival and spread of coronaviruses.
