Hold your mask up to light. Can you predict it?

For completeness, we analysed the consequences of facemask use in the absence of lock-down and other mitigation procedures. We be aware that, in scenarios 5c and 5d, the epidemic has not yet infected motor the populace to reach herd immunity even without the periodic lock-downs. The long-term dynamics of these outbreaks following your relaxation of lock-down are examined. It is clear that, in keeping with an epidemic by having an R0 valuation on approximately 4, the epidemic increases exponentially, resulting in quite high levels of infection. Here, as elsewhere, we believe that infection confers immunity, though that assumption can easily be relaxed by expanding the framework with free-living inoculum to include a SIRS model, where as time passes removed individuals could become susceptible again. 

Adoption of face mask wearing by 25% of the population decreases the level of infection in people. The effects increase with greater adoption. At 100% adoption, the condition progress curve is flattened significantly along with the final number of men and women infected is reduced. We remember that 100% facemask adoption without lock-down achieves an increased reduction inside final size epidemic, a lesser ‘total removed’ and a lower peak of active cases than lock-down without facemasks. These results are striking because the huge benefits accrue to the facemask wearer in addition to the people overall. We have assumed a reduction each in inhalation and exhalation of 50% of droplet inoculum in contrast to no facemask. 


The mask is constructed from rice paper possesses flower seeds. Its straps are manufactured from pure sheep’s wool. Even the glue employed to attach certain parts is manufactured using potato starch and water. 



Our analysis suggests that a higher proportion in the population would have to wear facemasks to attain reasonable impact in the intervention. In Hong Kong, 99% of survey respondents reported wearing facemasks when outside of their home.
