From the WHO guidance on face coverings:"Potential harms/disadvantagesThe likely disadvantages of the use of mask by healthy people in the general public include:• potential increased risk of self-contamination due to the manipulation of a face mask and subsequently touchingeyes with contaminated hands;(48, 49)• potential self-contamination that can occur if nonmedical masks are not changed when wet or soiled. Thiscan create favourable conditions for microorganism to amplify;• potential headache and/or breathing difficulties, depending on type of mask used;• potential development of facial skin lesions, irritant dermatitis or worsening acne, when used frequently forlong hours;(50)• difficulty with communicating clearly;• potential discomfort;(41, 51)• a false sense of security, leading to potentially lower adherence to other critical preventive measures such asphysical distancing and hand hygiene;• poor compliance with mask wearing, in particular by young children;• waste management issues; improper mask disposal leading to increased litter in public places, risk ofcontamination to street cleaners and environment hazard;• difficulty communicating for deaf persons who rely on lip reading;• disadvantages for or difficulty wearing them, especially for children, developmentally challenged persons, thosewith mental illness, elderly persons with cognitive impairment, those with asthma or chronic respiratory orbreathing problems, those who have had facial trauma or recent oral maxillofacial surgery, and those living in hotand humid environments. "https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masksGiven that few people follow the guidelines on handling, putting on and taking of these items I suggest that "potential increased risk of self-contamination due to the manipulation of a face mask and subsequently touchingeyes with contaminated hands" is a very real issue.Plus many will be spreading contamination by touching surfaces after fiddling with their masks.Based on the above, everyone should claim exemption.
