A Centers for Disease Control report released in September shows that masks and face coverings are not effective in preventing the spread of COVID-19, even for those people who consistently wear them.
A study conducted in the United States in July found that when they compared 154 “case-patients,” who tested positive for COVID-19, to a control group of 160 participants from the same health care facility who were symptomatic but tested negative, over 70 percent of the case-patients were contaminated with the virus and fell ill despite “always” wearing a mask.
“In the 14 days before illness onset, 71% of case-patients and 74% of control participants reported always using cloth face coverings or other mask types when in public,” the report stated.
In addition, over 14 percent of the case-patients said they “often” wore a face covering and were still infected with the virus. The study also demonstrates that under 4 percent of the case-patients became sick with the virus even though they “never” wore a mask or face covering.
