“All flies exposed to SARS-CoV-2-spiked media or milk substrates were positive for viral RNA at 4hr and 24hr post-exposure. Infectious virus was isolated only from the flies exposed to virus-spiked milk but not from those exposed to virus-spiked medium. Moreover, viral RNA was detected in environmental samples after contact with SARS-CoV-2 exposed flies, although no infectious virus was recovered from these samples.”
