A profoundly important study was conducted by German physician Dr. Zacharias Fögen to find out whether mandatory mask use influenced the COVID-19 case fatality rate in Kansas from August 1, 2020, to October 15, 2020.11 He chose the state of Kansas because, while it issued a mask mandate, counties were allowed to either opt in or out of it.
His analysis revealed that counties with a mask mandate had significantly higher case fatality rates than counties without a mask mandate. "These findings suggest that mask use might pose a yet unknown threat to the user instead of protecting them, making mask mandates a debatable epidemiologic intervention," he concluded.
That threat, he explained, may be something called the "Foegen effect" — the idea that deep re-inhalation of droplets and virions caught on facemasks might make COVID-19 infection more likely or more severe.
“The fundamentals of this effect are easily demonstrated when wearing a facemask and glasses at the same time by pulling the upper edge of the mask over the lower edge of the glasses. Droplets appear on the mask when breathing out and disappear when breathing in.”
"In the "Foegen effect," the virions spread (because of their smaller size) deeper into the respiratory tract. They bypass the bronchi and are inhaled deep into the alveoli, where they can cause pneumonia instead of bronchitis, which would be typical of a virus infection.
Furthermore, these virions bypass the multilayer squamous epithelial wall that they cannot pass into in vitro and most likely cannot pass into in vivo. Therefore, the only probable way for the virions to enter the blood vessels is through the alveoli."12
Wearing Masks Could Be Related to Long COVID
Fögen explained that wearing masks could end up increasing your overall viral load because, instead of exhaling virions from your respiratory tract and ridding your body of them, those virions are caught in the mask and returned. This might also have the effect of increasing the number of virions that pass through the mask, such that it becomes more than the number that would have been shed without a mask.
The fact that "hypercondensed droplets and pure virions in the mask might be blown outwards during expiration, resulting in aerosol transmission instead of droplet transmission" is another issue that could make transmission worse instead of better, and the use of "more protective" masks could also backfire, making COVID-19's long-term effects worse. Fögen explained:13
"The use of "better" masks (e.g., FFP2, FFP3) with a higher droplet-filtering capacity probably should cause an even stronger "Foegen effect" because the number of virions that are potentially re-inhaled increases in the same way that outward shedding is reduced.
Another salient point is that COVID-19-related long-term effects and multisystem inflammatory syndrome in children may all be a direct cause of the "Foegen effect." Virus entry into the alveoli and blood without being restricted to the upper respiratory tract and bronchi and can cause damage by initiating an (auto) immune reaction in most organs."
