In addition to suggesting how to make your mask fit better to reduce your risk, the health agency now suggests that certain risky places require better masks that offer superior "fit or filtration". They looked at the difference between wearing a three-layer cotton cloth mask or three-layer medical procedure mask alone, and then the effectiveness of wearing the cloth mask over the medical procedure mask.

But the CDC's updated mask guidance says people should not wear two disposable masks or combine a KN95 mask with any other type of mask.

Local reaction concerning the Centers for Disease Control's new suggestion to wear two masks is mixed.

Scientists have prescribed wearing a cloth mark on top of a surgical mask to provide the fullest protection.

Health officials also added recently discovered variants of the virus likely was a factor in releasing the new suggestion to double mask.

However, mask wearing has proven to limit the spread of coronavirus in areas where the practice is widely observed.

Overall, if two people are both wearing double masks, they reduce their possible exposure to aerosols by more than 96%.

The two strategies employed in the CDC's recent study - double masking and knotting and tucking the ear loops of a medical procedure mask - were both meant to create a tighter fit that provided more protection. "The second mask should push the edges of the inner mask against your face". Doing so, research suggests, drops the likelihood of virus transmission to more than 95%, particularly when mask straps are knotted around the ears for a tighter fit.

Should new COVID-19 variants send the number of cases in Douglas County in the wrong direction, and should the hospital become overwhelmed, Marcellino said the health department might need to recommend double masking. "And now these variants are circulating... whatever we can do to improve the fit of a mask to make it work better, the faster we can end this pandemic". "Multiple simple ways to improve fit have been demonstrated to be effective".
