coronavirus particles which could be inhaled by others and potentially spread the infection, new research has warned. Scientists have warned people to remember to put the seat down to cut the risk of catching viruses in this way.They also advise people clean the toilet seat before using it as floating virus particles could have settled on its surface and everyone should wash hands carefully after flushing.This is because virus particles may be present on the flush button and door handle.Publishing the findings in the journal Physics of Fluids, researchers said they could not be sure whether the particles were of sufficient viral load to pass on Covid-19 – but are advising people put the seat down before flushing just in case.But they did.
