The United States Centers for Disease Control and Prevention (CDC) changed positions this Friday and they asked Americans to always wear masks, both when they are outdoors and indoors, except at home in some cases.
The recommendation was not widely publicized by the CDC and, in fact, appears almost hidden in one of the reports it publishes weekly on the relationship between morbidity and mortality.
In this report, the CDC warns that the United States has entered “a phase of high transmission”, due to the drop in temperatures and the arrival of the Christmas celebrations. that push Americans to spend more time indoors, where transmission of the virus is easier.

Therefore, the CDC supports it it is now “consistent and correct” to recommend the use of masks at all times. In addition, they point out that the use of such protection is especially important when it is not possible to maintain a separation distance of at least two meters from other individuals.
The CDC also asks Americans wearing masks in your home when living with someone who may be infected, either through contact with another person, because they have recently traveled or have a higher risk job.
Until now, the CDC has held that masks were unnecessary outdoors as long as the safe distance was maintained. Nor did they recommend its use among those who shared the same house.

Currently, every minute, two people lose their lives to covid-19 in the United States, where the total death toll exceeds 277,000 and more than 14 million cases have been recorded since the start of the pandemic, the latest Johns Hopkins figures University.
This week, the World Health Organization (WHO) also recommended the generalization of the use of anti-covid masks in health care facilities, as well as transporting them indoors without adequate ventilation in regions with extensive coronavirus transmission.
It was the fourth update of the WHO recommendations on the use of face masks since the start of the pandemic. On this occasion, “the main changes (…) are an increased use of masks in health care facilities and details on the use of non-medical masks for the general public,” indicated the WHO.

These new recommendations are applicable in areas where there is a “cluster” (group) or community-wide transmission of the SARS-CoV-2 virus, which causes covid-19.
Under these circumstances, “WHO recommends wearing non-medical masks indoors (e.g. in shops, shared workplaces, schools) and also outdoors, when it is not possible to maintain the physical distance of at least one meter “.
On the other hand, the specialized agency of the United Nations recommends not using valve masks, which, like Transparent masks protect much less than conventional masks, in addition to not using them during intense physical activities.
