Coronaviruses have significantly changed 21st century medicine, healthcare systems, education, and the global economy by driving the ongoing coronavirus disease (COVID-19) pandemic. COVID-19 in humans is characterized by a wide range of symptoms, from asymptomatic to mild or severe illnesses, including death. The existing literature shows the roles of insect vectors in aiding the transmission of viral pathogens and the possible roles of some insects in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission. In this study, we briefly review the possibility of biological or mechanical transmission of SARS-CoV-2 by insects in the environment.
