A Thai study has found that, without facemasks, there was a 10% risk of being infected with Covid-19 in public toilets, but the risk increased to almost 100% if the Covid-19 infected person coughed or sneezed in the toilet. However, if both wore face masks, the risk was just 0.01%.
Researchers are now warning the public not to take off face masks while in public toilets. Thammanitchpol Denpetkul, a lecturer at the faculty of tropical medicine at Mahidol University, told the Bangkok Post that some masks are much more effective than others.
“Some cloth masks may not be good enough to protect against the virus … but if someone uses an N95 mask and wears it properly, the risk is one in 100,000.”
