Abstract
We studied the influence of weather conditions (air temperature, absolute and relative air humidity, atmospheric pressure, wind speed and geomagnetic activity) on the epidemic process of COVID-19 in Sumy that is a city in north-eastern Ukraine for the period 4.05.2020-22.03.2021. The study was carried out using nonparametric Kruskal-Wallis dispersive analysis. The obtained results show that all meteorological factors affect the COVID-19 incidence rate. The air temperature, absolute humidity and atmospheric pressure are the most important meteorological factors influencing COVID-19 epidemic process
Highlights
There are a lot of scientific researches proving relationship between fluctuations in epidemic process of infectious diseases and changes in weather conditions
The incidence rates were correlated with the average values of air temperature, wind speed, relative and absolute humidity, atmospheric pressure and geomagnetic activity in the 14-day period before the onset of clinical symptoms
The variation series were formed in such a way that the meteorological indicators "lagged" behind the incidence rate, and each incidence was corresponded to the average values of temperature, relative and absolute humidity, wind speed, geomagnetic activity, and atmospheric pressure in the period from the 17th to the 3rd day before the final diagnosis
Summary
There are a lot of scientific researches proving relationship between fluctuations in epidemic process of infectious diseases and changes in weather conditions. Acute respiratory viral infections, viral hepatitis A and E, shigellosis, leptospirosis, tularemia, malaria and many other infectious diseases have a pronounced seasonality. Meteorological factors, such as temperature, humidity, atmospheric pressure can affect the intensity of the epidemic process directly or indirectly. In some cases, this may be due to changes in the survival of pathogens in the environment [1,2], in others - with fluctuations in the susceptibility of the organism to the pathogen as a result of changes in physiological responses of the human body in response to weather factors [3,4]. The objective is to study the relationship between the incidence of COVID19 and meteorological factors in Sumy that is a city in north-eastern Ukraine
