Even with variants that may be more contagious, there is no evidence to suggest that the form of transmission has changed.
Tissue masks also remain effective against new variants of coronaviruses, as the form of transmission remains the same, the World Health Organization (WHO) said Friday (22), which does not shy away from changing its recommendations.
“Anyone under the age of 60, who has no specific health problems, can use non-surgical tissue masks,” said WHO epidemic management person Maria Van Kerkhov.
“In areas where the virus spreads, it is necessary to wear masks when there are crowds of people and it is impossible to stay at least one meter from each other, and even in rooms with little or poor ventilation,” he said. Conference added to the news.
Germany and Austria have only used medical masks (surgical or FFP2) in shops and transportation.
The French government is asking to stop using some fabric masks, such as those manufactured at home because it is believed that they do not filter enough with the presence of newer, more infectious variants of the new coronovirus.
Maria Van Kerkhov said, “Countries are free to take the measures they necessarily require.”
But, even with such adaptations, which may be more contagious, “we have no evidence to suggest that the form of transmission has changed,” he explained. Therefore, “at this stage we do not intend to change the current recommendations”.
