Are masks bad for you? – The Spectator

Could masks be making us sick? That’s the suggestion in a Japanese study, published this week in Nature’s Scientific Report’s journal, which looked at bacterial and fungal growth on face masks worn during the pandemic. The results may put you off your tea.

The study looked at the masks of 109 people and shows that bacteria grows in bigger colonies on the inside of the mask compared with the outside. The opposite was true for fungus. Wearing the same mask for a long period of time ‘significantly’ increased the amount of fungus growing on a mask but had no effect on the amount of bacteria.

Every mask bar one – 99 per cent of the masks examined – contained bacterial colonies on the inside and 94 per cent on the outside. The type of mask worn – cloth or disposable – made no difference to the spread of bacteria. On the other hand, fungus was found on the outside of 95 per cent of masks and on the inside of 79 per cent. An interesting finding was that bacterial counts were lower on the insides of masks worn by women. It suggested this may be because they wear makeup and take better care of their skin.

Bacterial and fungal isolation from face masks under the COVID-19 pandemic – Nature

The COVID-19 pandemic has led people to wear face masks daily in public. Although the effectiveness of face masks against viral transmission has been extensively studied, there have been few reports on potential hygiene issues due to bacteria and fungi attached to the face masks. We aimed to (1) quantify and identify the bacteria and fungi attaching to the masks, and (2) investigate whether the mask-attached microbes could be associated with the types and usage of the masks and individual lifestyles. We surveyed 109 volunteers on their mask usage and lifestyles, and cultured bacteria and fungi from either the face-side or outer-side of their masks. The bacterial colony numbers were greater on the face-side than the outer-side; the fungal colony numbers were fewer on the face-side than the outer-side. A longer mask usage significantly increased the fungal colony numbers but not the bacterial colony numbers. Although most identified microbes were non-pathogenic in humans; Staphylococcus epidermidis, Staphylococcus aureus, and Cladosporium, we found several pathogenic microbes; Bacillus cereus, Staphylococcus saprophyticus, Aspergillus, and Microsporum. We also found no associations of mask-attached microbes with the transportation methods or gargling. We propose that immunocompromised people should avoid repeated use of masks to prevent microbial infection.

The Dangers of Masks – Paul E Alexander MSc PhD, AIER

Emergent reports, albeit nascent and anecdotal but nevertheless vitally important (and will be clarified and defined in time) regarding the manufacture of masks, where, “many of them (face masks) are made of polyester, so you have a microplastic problem…many of the face masks would contain polyester with chlorine compounds…if I have the mask in front of my face, then of course I inhale the microplastic directly and these substances are much more toxic than if you swallow them, as they get directly into the nervous system.”

There are also reports of toxic mould, fungi, and bacteria that can pose a significant threat to the immune system by potentially weakening it. Of particular concern to us is the recent report of breathing in synthetic fibers in the face masks. This is of serious concern. “Loose particulate was seen on each type of mask. Also, tight and loose fibers were seen on each type of mask. If every foreign particle and every fiber in every facemask is always secure and not detachable by airflow, then there should be no risk of inhalation of such particles and fibers. However, if even a small portion of mask fibers is detachable by inspiratory airflow, or if there is debris in mask manufacture or packaging or handling, then there is the possibility of not only entry of foreign material to the airways, but also entry to deep lung tissue, and potential pathological consequences of foreign bodies in the lungs.”
