The World Health Organization (WHO) changed its attitude towards gags, and caught up with the global trend when it recommended its use in crowded public places, to stop the emerging corona virus (Corvid-19) infection.
However, the Geneva-based United Nations Health Organization stressed that masks can increase health risks if people pollute them by touching them with dirty hands.
"The muzzles can create a false sense of safety," said WHO Director-General Tidros Adhanom Gebresus at an online news conference.
He warned that gags could not replace hand hygiene and spacing, or track patients and their social connections.
Tidros said: “I cannot say this clearly enough: the masks alone will not protect you from (Covid 19).”
The World Health Organization did not urge the mass use of muzzles in its previous guidance on this topic in early April. Tedros said, the day before yesterday, that governments should encourage its use where there is widespread transmission of the virus, and where it is difficult to maintain a safe distance from others “such as public transportation, in stores, or in other closed or crowded environments.”
