Factors contributing to the occurrence of emerging infectious diseases including COVID-19
Keywords:
emerging infectious diseases, COVID-19, contributing factors, SARS-CoV-2Abstract
Emerging infectious diseases (EIDs) are problems that directly affect not only people’s health but also the public health system, the economy, and even national security. The newly emerging Coronavirus Disease 2019 or COVID-19, which has infected millions of people worldwide, causing hundreds of thousands of deaths, has created a global panic about the epidemic situation. It is thus important to understand the factors contributing to the occurrence of these EIDs as they are the basis for creating and implementing measures to control the diseases as well as for preventing the occurrence of other EIDs in the future. This review article
presents information about EIDs by focusing on the factors that promote the occurrence of these diseases and incorporating relevant examples of EIDs that have emerged within the 21st century. The factors were categorized into 4 groups namely 1) factors relating to pathogens; 2) population, demographic, and social factors; 3) environmental factors; and 4) factors relating to public health systems. Analyses of factors related to the occurrence of COVID-19 were also included.
