According to my sources in the Emergency Room at Enloe Hospital, there has been a spike in patients being treated for respiratory infections. It is suspected these phenomena are due to wearing disposable masks too many times. Over-time masks can become unsanitary and laden with germs, bacteria, and mold. This potentially could increase the chance of lung infections.
Note; The information about possible dirty mask infections is not based on a scientific study, but rather on medical observations at the ER. The CDC has long stated that prolonged wearing of masks should not be of any concern because the chances and the chances of infection are extremely low.
