Estimation of COVID-19 patient numbers using artificial neural networks based on air pollutant concentration levels
Abstract
The dilemma between health concerns and the economy is apparent in the context of strategic decision making during the
pandemic. In particular, estimating the patient numbers and achieving an informed management of the dilemma are crucial
in terms of the strategic decisions to be taken. The Covid-19 pandemic presents an important case in this context. Sustaining
the eforts to cope with and to put an end to this pandemic requires investigation of the spread and infection mechanisms of
the disease, and the factors which facilitate its spread. Covid-19 symptoms culminating in respiratory failure are known to
cause death. Since air quality is one of the most signifcant factors in the progression of lung and respiratory diseases, it is
aimed to estimate the number of Covid-19 patients corresponding to the pollutant parameters (PM10, PM2.5, SO2, NOX,
NO2, CO, O3) after determining the relationship between air pollutant parameters and Covid-19 patient numbers in Turkey.
For this purpose, artifcial neural network was used to estimate the number of Covid-19 patients corresponding to air pollutant parameters in Turkey. To obtain highest accuracy levels in terms of network architecture structure, various network
structures were tested. The optimal performance level was developed with 15 neurons combined with one hidden layer,
which achieved a network performance level as high as 0.97342. It was concluded that Covid-19 disease is afected from air
pollutant parameters and the number of patients can be estimated depending on these parameters by this study. Since it is
known that the struggle against the pandemic should be handled in all aspects, the result of the study will contribute to the
establishment of environmental decisions and precautions.
