As a result of the effects of the Covid-19 virus, which is thought to have emerged in China in December 2019 and caused the death of many people, 2020 has been declared a global pandemic year by the World Health Organization (WHO) as of March 2020. The distribution and consequences of the Covid-19 epidemic vary according to climates, regions, demographic structure, population, hygiene conditions and contamination. It has been proven by scientific research that the disease is transmitted from person to person through droplets and contact. Vaccine studies are continuing to prevent the Covid-19 epidemic. It is seen that it is not possible to return to normal life for a long time, and that people should follow all precautions with the same meticulousness even if they are vaccinated. Those who have to work without social distance in their workplaces and those who have to be together in public areas are at higher risk of contracting the Covid-19 virus. For this reason, the most important measures to prevent the spread of the virus in the community have been determined by the authorities as hygiene, maintaining social distance, staying in quarantine and wearing a mask. Accordingly, in this study, the effects of mask use, duration of stay in the closed environment and ventilation of the environment on the risk of transmission of the Covid-19 epidemic were investigated, and the relationships between these parameters were evaluated with the fuzzy logic method. Situations that can minimize the risk of Covid-19 virus transmission and maximize it have been identified.Covid-19, fuzzy logic, use of mask, social distance, risk of transmission
