He now recommends that people also wear masks in their own homes when visiting by outsiders, if ventilation is not good or cannot be properly assessed. This applies “regardless of whether a distance of at least one meter can be maintained,” the recommendations updated Wednesday say.
Masks should not be worn on the arm or wrist, or down to the chin or neck when not over the mouth and nose, according to the WHO. They should be kept in clean, reusable plastic bags.
In hospitals and care facilities, everyone working there must now wear masks, including cleaning and kitchen staff and office workers, not just care staff.
Despite the new recommendations, the WHO maintains that the benefit of using a general mask in healthy people has not yet been clearly demonstrated: “At the moment, there is only limited and contradictory scientific evidence on the effectiveness of using a mask in healthy people against respiratory virus infections, including Sars-CoV-2 to prevent “.
A study published in November with 4,862 participants, in which some wore masks and others didn’t, found no difference in Sars-CoV-2 coronavirus infections. Smaller studies have found that wearing a mask in contact with infected people significantly reduces the risk of infection. Other studies have compared regions with and without a mask and found a decrease in Covid-19 diseases where masks were used.
