I am going to insert my thoughts here on the topic of masks.
[ Truncated ]
It can be very confusing, Layla. Particularly when WHO and the CDC are contradicting each other in regards to masks. https://sciencebasedmedicine.org/do-masks-work/
I have been following this very closely, as I am at high risk for contracting covid-19. While I have purchased masks to support small business or friends for purposes of income; I was provided two professional masks by my healthcare physician. So the latter is what I wear when I must go out. Additionally, I also rub thieves oil on the outside of the mask ( as well as my hands, door handles/knob, steering wheel, etc. ). I figured if it stopped thieves from getting the bubonic plague it will help me from getting covid-19.
Anyway . . . Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets. Our results indicate that surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals.
More importantly, there is a recent systematic review of 19 trials, which concludes:
The study suggests that community mask use by well people could be beneficial, particularly for COVID-19, where transmission may be pre-symptomatic. The studies of masks as source control also suggest a benefit, and may be important during the COVID-19 pandemic in universal community face mask use as well as in health care settings. Trials in healthcare workers support the use of respirators continuously during a shift. This may prevent health worker infections and deaths from COVID-19, as aerosolisation in the hospital setting has been documented.
My heart goes out to healthcare professionals whose mask creates a vacuum when they take their off after a shift. It all seems so much; however, perspective changes when a friend or family member is diagnosed positive. It then becomes a small step.
Our ( NC ) governor just issued an executive order outlining mandatory mask wearing in public where social distancing cannot be avoided: https://drive.google.com/file/d/1PD5b7SLTbT8PnrX1Or4fSPvsJvNRCUgL/view
In that executive order it merely says "cloth face covering", which, in essence could be a mere bandana.
I agree with you that we need more clarification and studies to ensure our own personal safety. While I only have mine on for an hour or so at the most, I do feel for you and others who must wear them all day.
