The ongoing novel coronavirus disease (COVID-19) pandemic has already infected millions worldwide and, with no vaccine available, interventions to mitigate transmission are urgently needed. While there is broad agreement that travel restrictions and social distancing are beneficial in limiting spread, recommendations around face mask use are inconsistent.
Here, we use mathematical modeling to examine the epidemiological impact of face masks, considering resource limitations and a range of supply and demand dynamics. Even with a limited protective effect, face masks can reduce total infections and deaths, and can delay the peak time of the epidemic.
However, random distribution of masks is generally suboptimal; prioritized coverage of the elderly improves outcomes while retaining resources for detected cases provides further mitigation under a range of scenarios. Face mask use, particularly for a pathogen with the relatively common asymptomatic carriage, is an effective intervention strategy, while optimized distribution is important when resources are limited.
A lot of Countries are limiting movement without the mask, from going to restaurants, gyms, grocery stores, and even in your workplace. Why not make your mask or bandana a unique one that reflects your style or personality.
