CDC Reaffirms Effectiveness of Face Masks
The recent surge in coronavirus infections has caused some to question the use and effectiveness of the various types of face masks.
The U.S. Centers for Disease Control and Prevention recently posted a scientific brief confirming that mask usage reduces the spread of the virus.
The study indicates that masks provide a means of controlling emission from the source as well as providing personal protection for the mask wearer.
“Cloth masks not only effectively block most large droplets but they can also block the exhalation of fine droplets and particles,” the brief noted.
“The prevention benefit of masking is derived from the combination of source control and personal protection for the mask wearer.”
The brief said “further research is needed to expand the evidence base for the protective effect of cloth masks and in particular to identify the combinations of materials that maximize both their blocking and filtering effectiveness, as well as fit, comfort, durability, and consumer appeal.”
OSHA has already issued a statement that face masks don’t deplete oxygen or cause carbon dioxide to build up.
In Connecticut, face masks are mandatory in all workplaces.
Here is more guidance from OSHA on workplace face coverings.
“Adopting universal masking policies can help avert future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distancing, hand hygiene, and adequate ventilation,” the CDC said.
