A health expert has displayed how wearing a face mask could drastically reduce the risk of spreading coronavirus to others with some shocking images.
Explaining how a face covering can prevent someone carrying the potentially deadly virus from passing it on, he wrote on Twitter, ‘What does a mask do? Blocks respiratory droplets coming from your mouth and throat.’
Sharing some photographs, Dr. Davis described how he had coughed, sneezed and breathed onto agar culture plates, first wearing a mask and then without wearing one.
The bacteria colonies were then allowed to grow, displaying how easily respiratory droplets are spread when a mask isn’t in the way.
He then carried out the same tests from varying distances, again showing that masks block almost all of the droplets.
‘First, I sneezed, sang, talked & coughed toward an agar culture plate with or without a mask. Bacteria colonies show where droplets landed. A mask blocks virtually all of them,’ he wrote.
‘Colonies of normal bacteria from my mouth/throat show the spread of large respiratory droplets, like the kind we think mostly spread #COVID19, and how a mask can block them.’
The medical pro went on to insist he feels we need to make wearing a mask as much of a common hygiene practice as washing our hands.
‘We wash hands after using the bathroom & wipe noses on tissues. Masks/face shields need to be just another normalized act of hygiene,’ he said.
This comes in light of the recent news that pubs and restaurants will re-open across the UK this weekend, with the current social distancing advice telling the public to remain at a minimum of one metre apart.
Meanwhile, it is still compulsory to wear a mask while using public transport.
