Why Wearing A Mask Is A Very Powerful Thing

The COVID-19 pandemic has reshaped life as we all know it. Many of us are staying home, avoiding individuals on the street and altering daily habits, like going to school or work, in methods we by no means imagined.

While we are altering old behaviours, there are new routines we have to adopt. Before everything is the behavior of wearing a mask or face covering whenever we are in a public space.

Based mostly on our prior work in outbreaks of infectious diseases, we know that clear, consistent messages about what folks can do to protect themselves and their neighborhood are critical. By that measure, the messaging on masks has been confusing.

Early within the pandemic, the general public was told to not wear masks. This was pushed by the longstanding recognition that customary surgical masks (additionally called medical masks) are insufficient to protect the wearer from many respiratory pathogens, as well as the priority about diverting limited provides from healthcare settings.

Science is the pursuit of information and understanding, and it inevitably adjustments the way in which we see the world. Because of the tireless efforts of scientists everywhere, we've got compressed years of analysis on the COVID-19 virus into months. This has led to a fast evolution of policies and recommendations, and not surprisingly some skepticism concerning the advice of experts.

These are a few of the things we’ve learned:

Masks and face coverings can prevent the wearer from transmitting the COVID-19 virus to others and may provide some protection to the wearer. A number of studies have shown that face coverings can comprise droplets expelled from the wearer, which are accountable for almost all of transmission of the virus. This 'supply control' approach displays a shift in thinking from a 'medical' perspective (will it protect the wearer?) to a 'public health' perspective (will it help reduce neighborhood transmission and risk for everyone?).
Many individuals with COVID-19 are unaware they are carrying the virus. It is estimated that 40% of persons with COVID-19 are asymptomatic however potentially able to transmit the virus to others. In the absence widespread screening tests, we've no means of identifying many people who are silently transmitting the virus of their community.
Universal mask use can significantly reduce virus transmission in the neighborhood by preventing anybody, together with those who are unwittingly carrying the virus, from transmitting it to others. Disease modeling suggests masks worn by significant portions of the inhabitants, coupled with different measures, may end in substantial reductions in case numbers and deaths.
Masks aren't good obstacles to transmission, however they don’t should be excellent if they aren’t used alone. Universal mask use must be accompanied by other public health measures similar to physical distancing, testing, contact tracing and restrictions on massive gatherings. These measures aren’t good either, however when many imperfect measures are mixed at a community level, they can be very efficient at slowing transmission and reducing infections.

Masks can also reduce the inequitable impact of the pandemic, significantly for those who live in crowded environments the place physical distancing is troublesome, and for many who work in frontline roles where there's a greater risk of publicity to the virus.
