The World Health Organization has issued new recommendations on the use of masks during the covid-19 pandemic, including advising health professionals and the general population to avoid wearing masks with valves.
The recommendations have been made known through the publication of a new guide, which states that users of valve masks may exhale insufficiently filtered air, and therefore “are useless for control,” the text emphasizes.
The entity insisted on recommending the permanent use of medical masks to both healthcare professionals and the general population in areas with lower risk of airborne or aerosol infection, while in higher risk areas, such as care areas. Patients with Covid-19 reiterated the use of maximum protection, such as N95, FFP2 or FFP3.
They stressed that medical masks are the most recommended to ensure the protection of risk groups such as the elderly and people with chronic lung disease, cancer, diabetes or cardiovascular problems, in contexts where a physical distance of at least one meter cannot be guaranteed. .
Likewise, he advised the general population to use non-medical masks, such as fabric masks, for use in indoor areas such as shops, offices, or schools.
