Coronavirus to Spread via Aerosols Through Drain Pipes

A new study reveals that the pandemic causing virus may spread via aerosols in drainage pipes in bathrooms after examining the bathroom of a closed apartment in China. Several studies have revealed that COVID-19 can spread through aerosols in the hospital setting as well. Even though initially the WHO said that the airborne transmission of SARS-CoV-2 could occur during medical procedures such as nebulization and other procedures that produce aerosols etc., however, recent evidence has shown that airborne transmission can also spread in enclosed areas where there is poor ventilation, such as offices.

The scientist conducted an on-site experiment to evaluate if the virus could spread through waste pipes through tiny airborne particles, which are generated by the force of a toilet flush. The team noted an incident in February, when SARS-CoV-2 RNA on surface samples, such as those from the shower handle, faucet, and sink, was found in a bathroom of an unoccupied apartment. The team also cited other instances where the airborne spread of the SARS-CoV-2 is more likely. For instance, a choir rehearsal in Washington in the United States has led to the infection of 53 out of the 61 attendees, while two of these patients had died. The rehearsal imposed adequate precautions for droplet transmission, and none of the attendees had symptoms.

The team urges governments and healthcare settings to impose precautionary control strategies that are essential for the protection of public health, use of face masks, and other strict measures.
