From article: Modern influenza studies also hold lessons.
Influenza and covid-19 transmit the same way, and a careful study of
seasonal influenza transmission found that a combination of masks and
hand-washing reduced illness dramatically after six weeks, while an analysis of multiple studies of mask use and
hand-washing during the 2009 swine flu pandemic concluded the same thing: the
combination of the two provided significant protection.
Even more important in interrupting transmission is social
distancing. Simply talking face to face seems to be a major mode of
transmission. Although quantifiable data supporting that statement has not yet
been extracted and analyzed, that is the view of an emerging consensus of
public-health experts.
Distancing oneself, using masks, washing hands, taking such
other preventive actions as avoiding public bathrooms (bowel movements and
toilet flushing expel airborne virus), and, of course, staying home when sick
are not magic bullets, but they all impact spread. As in army barracks in 1918,
as in SARS among health-care workers, compliance matters.
Individuals who employ all these measures can greatly enhance
their chances of avoiding infection, and, even in the absence of adequate
testing and tracing, can have considerable impact on society-wide spread.
Such measures are not ideological, even if the great irony in
this pandemic is that they have become so.
