The World Health Organization (WHO) has updated its guidelines for fighting the corona pandemic.
She now recommends that governments around the world ask the population to wear proper face and mouth masks in public areas.
This helps control the spread of the virus and reduce the number of Covid-19 patients.
The WHO has been convinced by recent research of the benefits of mouth masks but stresses that wearing them is just one measure in a whole range that can limit virus transmission.
A mouth mask alone should not give a false sense of security.
“We advise governments to encourage people to wear masks in public places, notably a non-medical mask,” said Maria Van Kerkhove, WHO technical expert on Covid-19.
“We now have evidence that if used properly, it can act as a barrier to potentially infectious droplets.”
In many countries, including the Netherlands, wearing a non-medical mask in public transport, for example, is already mandatory.
