Para aumentar la protección frente al coronavirus, los Centros para el Control y la Prevención de Enfermedades (CDC) de Estados Unidos recomiendan - no exigen - el uso de la doble mascarilla.

"Now with these new variants [of the virus] circulating ... what we can do to improve the adjustment of a mask to make it work better, it will allow us to end this pandemic faster," said John T.Brooks, medical head of the CDC responsible for the study that supports the recommendation of the double mask, according to The Washington Post.

En los campus de la University of Texas aconsejan utilizarla “dado el aumento del riesgo de transmisión con las nuevas variantes del covid-19”, como la británica, que es más contagiosa.

El alcalde de Nueva York, Bill de Blasio, ha pedido a los residentes de esa ciudad que utilicen doble mascarilla al menos hasta junio.

“Una mascarilla al menos, pero si quieres estar realmente seguro, consigue que esté más ajustada con una segunda mascarilla”, comentó Anthony Fauci, director del Instituto Nacional de Alergias y Enfermedades Infecciosas y asesor de la Casa Blanca sobre el coronavirus, en la cadena NBC, tras afirmar que él ha utilizado la doble mascarilla ocasionalmente.
