Insects are affected by a diverse combination of viruses. Majority of the viruses affecting insects are hostspecific and non-pathogenic to humans. While blood-sucking insects do not transmit COVID-19, those feeding on human and animal wastes like houseflies and cockroaches may be capable of transmitting SARSCoV- 2 coronavirus. However, studies monitoring adhesion capacity, permanence and active dissemination of SARS-CoV-2 coronavirus in houseflies and cockroaches are yet to be assessed. Further studies are needed to explore the transmission and pathogenicity mechanism of COVID-19 by different insect vectors.
