Why Wearing A Masks Is A Very Powerful Thing

The COVID-19 pandemic has reshaped life as we all know it. Many people are staying house, avoiding individuals on the street and altering daily habits, like going to school or work, in methods we never imagined.

While we are changing old behaviours, there are new routines we have to adopt. Firstly is the behavior of wearing a mask or face covering each time we're in a public space.

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

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

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

These are some of the things we’ve realized:

Masks and face coverings can prevent the wearer from transmitting the COVID-19 virus to others and will provide some protection to the wearer. Multiple research have shown that face coverings can contain droplets expelled from the wearer, which are responsible for almost all of transmission of the virus. This 'supply control' approach reflects a shift in thinking from a 'medical' perspective (will it protect the wearer?) to a 'public health' perspective (will it help reduce community transmission and risk for everybody?).
Many people with COVID-19 are unaware they are carrying the virus. It's estimated that 40% of individuals with COVID-19 are asymptomatic but probably able to transmit the virus to others. Within the absence widespread screening tests, we now have no method of figuring out many people who are silently transmitting the virus of their community.
Universal masks use can significantly reduce virus transmission in the community by stopping anybody, together with those who are unwittingly carrying the virus, from transmitting it to others. Disease modeling suggests masks worn by significant parts of the population, coupled with other measures, could lead to 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 masks use must be accompanied by other public health measures resembling physical distancing, testing, contact tracing and restrictions on giant gatherings. These measures aren’t excellent both, however when many imperfect measures are combined at a group stage, they are often very effective at slowing transmission and reducing infections.

Masks can also reduce the inequitable impact of the pandemic, notably for individuals who live in crowded environments where physical distancing is difficult, and for those who work in frontline roles the place there's a larger risk of exposure to the virus.
