In December 2019, the World Health Organization (WHO) declared an epidemic due to the outbreak of the coronavirus in Wuhan, China. With the outbreak of the COVID-19 epidemic, it is still unclear how long the negative economic impact on the world will continue. In particular, the imposition of public or partial travel restrictions in many countries has led to widespread change in COVID-19, which has significantly altered consumer behavior and shaped the industry. While physical stores are plagued by epidemics due to customer actions and preferences, online retailers are increasing their sales volume and constantly gaining customers.Consumers have begun to prefer e-commerce, which is the fastest and most practical way to meet their needs in an epidemic environment. E-commerce is a way to minimize physical interaction, apart from receiving burdens. However, direct access to the product is very important not only for health, but also for practical savings, time and energy. The aim of this study was to investigate the impact of COVID-19, an infectious disease, on e-commerce and to assess changes in demand for different e-commerce products and product groups during the COVID-19 epidemic.
