In addition to these factors, potential advantages of the use of mask by healthy people in the community setting include reducing potential exposure risk from infected person during the “pre-symptomatic” period and stigmatization of individuals wearing mask for source control.
However, the following potential risks should be carefully taken into account in any decision-making process:
• self-contamination that can occur by touching and reusing contaminated mask
• depending on type of mask used, potential breathing difficulties
• false sense of security, leading to potentially less adherence to other preventive measures such as physical distancing and hand hygiene
• diversion of mask supplies and consequent shortage of mask for health care workers
• diversion of resources from effective public health measures, such as hand hygiene
Whatever approach is taken, it is important to develop a strong communication strategy to explain to the population the circumstances, criteria, and reasons for decisions. The population should receive clear instructions on what masks to wear, when and how (see mask management section), and on the importance of continuing to strictly follow all other IPC measures (e.g., hand hygiene, physical distancing, and others).
