The CDC warned the public not to replace masks with protective masks.

The U.S. Centers for Disease Control and Prevention (CDC) believes masks are less effective than masks in stopping the spread of the new coronavirus,media BGR reported. The CDC explicitly warns individuals not to replace cloth masks with protective masks. Although most people often choose to wear a general surgical mask or other type of cloth mask in public, someone still wears a mask. In particular, the CDC notes that masks are not recommended and that masks are not as effective as people think.

The CDC warned the public not to replace masks with protective masks.

As the CDC has clearly pointed out, there is no evidence that masks offer the same safety benefits as masks.

It is not known whether the mask will provide any benefits as source control to protect others from the injection of respiratory particles. The CDC does not recommend the use of masks in normal daily activities, nor does it recommend them as a substitute for cloth masks. Some people may choose to use a mask when they need to be in constant close contact with others. If you use a mask without a mask, the mask should wrap around both sides of the wearer’s face and extend below the chin.

In addition, a 2014 study called “The Effectiveness of Masks to Cough Aerosol Droplets in Cough Simulators” found that masks, while effective immediately after coughing, were less effective at smaller aerosol particles, which sometimes stay in the air for longer periods of time.

Our results suggest that health care providers may inhale infectious particles in the air when treating cough patients. Protective masks can significantly reduce the chance of short-term exposure to large infectious aerosol particles by health care workers, but smaller particles can stay in the air for longer periods of time and are more likely to flow around the mask and be inhaled. As a result, the mask provides a useful measure of respiratory protection for staff caring for patients with respiratory infections. However, they cannot be used as an alternative to respiratory protection when respiratory protection is needed.
