The Centers for Disease Control and Prevention (CDC) announced on Friday that the US has entered a “high-risk phase of coronavirus transmission” due to cold weather forcing Americans to spend more time indoors.
For the first time, the CDC called for “widespread use of masks” both indoors and out. CDC chief Robert Redfield has called masks “the most important public health tool” to combat the spread of the coronavirus.
The CDC previously recommended wearing masks in busy public places. The report emphasized that wearing masks is still most important indoors and outdoors when social distance is not possible. Wearing masks at home is recommended in case of illness of a family member, or an increased risk of illness in a family member, for example, if his profession is associated with the risk of infection.
In the United States, 277 thousand people became victims of COVID-19, almost 14.3 million cases of the disease were registered. According to the CDC, in about half of cases, the source of infection is people who carry COVID-19 without symptoms.
