Well this is disappointing. Trump campaign email trying to get me to mask up. No.
Should have included the embedded link.

Yea, maybe you should do some light reading.
Cloth masks are ineffective as source control and PPE, surgical masks have some role to play in preventing emissions from infected patients, and respirators are the best choice for protecting healthcare and other frontline workers, but not recommended for source control. These recommendations apply to pandemic and non-pandemic situations.

A cluster randomised trial of cloth masks compared with medical masks in healthcare workers
We have provided the first clinical efficacy data of cloth masks, which suggest HCWs should not use cloth masks as protection against respiratory infection. Cloth masks resulted in significantly higher rates of infection than medical masks, and also performed worse than the control arm. The controls were HCWs who observed standard practice, which involved mask use in the majority, albeit with lower compliance than in the intervention arms. The control HCWs also used medical masks more often than cloth masks. When we analysed all mask-wearers including controls, the higher risk of cloth masks was seen for laboratory-confirmed respiratory viral infection.

This experiment did not include N95 masks and does not reflect the actual transmission of infection from patients with COVID-19 wearing different types of masks. We do not know whether masks shorten the travel distance of droplets during coughing. Further study is needed to recommend whether face masks decrease transmission of virus from asymptomatic individuals or those with suspected COVID-19 who are not coughing.
In conclusion, both surgical and cotton masks seem to be ineffective in preventing the dissemination of SARS–CoV-2 from the coughs of patients with COVID-19 to the environment and external mask surface.

Jenny Harries, deputy chief medical officer, said the masks could “actually trap the virus” and cause the person wearing it to breathe it in.

The confirmed effectiveness of medical masks is crucially important for lower-resource and emergency settings lacking access to N95 respirators. In such cases, single-use medical masks are preferable to cloth masks, for which there is no evidence of protection and which might facilitate transmission of pathogens when used repeatedly without adequate sterilization [8].
We found no clear benefit of either medical masks or N95 respirators against pH1N1. However, current policies mandating standard and droplet precautions when performing routine care for influenza patients are reasonable. RCTs conducted in community settings have demonstrated protective effects of medical masks in combination with hand-hygiene and other infection control interventions

Flu virus is about 1000 times smaller than the width of a human hair. This study looks at the pore sizes of 20 different cotton masks versus N-95 surgical masks.
The researchers found that all of the cotton masks had pore sizes that were bigger than the width of a human hair – and got even bigger after washing. This means that the width of the holes in every cotton mask are 1000 times bigger than the size of the corona virus. Like trying to catch a fish with a net where the holes were 1000 times bigger than the fish you were trying to catch. surgical masks might stop bacteria – which are ten times bigger than viruses.

You honestly think it is going to stop with masks? Masks will somehow get the governors to allow in person voting? I am shut down now with a mask "order" in place, nothing has changed and nothing will as long as we continue to allow this overreach and give away our freedoms like candy on Halloween.
