A new study by American researchers from Kansas State University and Agricultural Research Service have alarmingly found that house flies can carry the SARS-CoV-2 coronavirus for up to 24 hours after exposure and are potential transmission vectors of the SARS-CoV-2 coronavirus!



House flies are known to transmit bacterial, parasitic and viral diseases to humans and animals as mechanical vectors. Previous studies have shown that house flies can mechanically transmit coronaviruses, such as turkey coronavirus; however, the house fly’s role in SARS-CoV-2 transmission was not explored until now. The goal of the study was to investigate the potential of house flies to mechanically transmit SARS-CoV-2.
 
Hence for this purpose, it was determined whether house flies can acquire SARS-CoV-2, harbor live virus and mechanically transmit the virus to naive substrates and surfaces.
 
Separate studies were performed to address the study objectives. In the first study, house flies were tested for infectivity after exposure to SARS-CoV-2-spiked medium or milk. In the second study, environmental samples were tested for infectivity after contact with SARS-CoV-2-exposed flies. During both studies, samples were collected at various time points post-exposure and evaluated by SARS-CoV-2-specific RT-qPCR and virus isolation.
 
It was alarmingly found that all flies exposed to SARS-CoV-2-spiked media or milk substrates were positive for viral RNA at 4 h and 24 h 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.
 
Under laboratory conditions, house flies acquired and harbored infectious SARS-CoV-2 for up to 24 h post-exposure. In addition, house flies were able to mechanically transmit SARS-CoV-2 genomic RNA to the surrounding environment up to 24 h post-exposure. Further studies are warranted to determine if house fly transmission occurs naturally and the potential public health implications of such events.
 
The studies were published in the peer reviewed journal: Parasites & Vectors. https://advances.sciencemag.org/content/early/2021/04/22/sciadv.abg7607
 
The SARS-CoV-2, the virus that causes the coronavirus disease (COVID-19), primarily spreads through respiratory droplets expelled when an infected person sneezes coughs or speaks.
 
It was also noted that in some instances, the droplets turn to aerosols and travel long distances or land on surfaces, leading to contact transmission.
 
The study team found that house flies can acquire and harbor infectious SARS-CoV-2 for up to 24 hours after exposure.
