Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly throughout the world since the first cases of coronavirus disease 2019 (COVID-19) were observed in December 2019 in Wuhan, China. It has been suspected that infected persons who remain asymptomatic play a significant role in the ongoing pandemic, but their relative number and effect have been uncertain. The authors sought to review and synthesize the available evidence on asymptomatic SARS-CoV-2 infection. Asymptomatic persons seem to account for approximately 40% to 45% of SARS-CoV-2 infections, and they can transmit the virus to others for an extended period, perhaps longer than 14 days. Asymptomatic infection may be associated with subclinical lung abnormalities, as detected by computed tomography. Because of the high risk for silent spread by asymptomatic persons, it is imperative that testing programs include those without symptoms. To supplement conventional diagnostic testing, which is constrained by capacity, cost, and its one-off nature, innovative tactics for public health surveillance, such as crowdsourcing digital wearable data and monitoring sewage sludge, might be helpful.

This is much worse than I had imagined. Distance from people you are not normally around. I move over at public places when someone starts to break the 6-foot barrier and when I can’t, I firmly ask them to distance.

Mask up when in public and consider the safety of your mask. It needs to fit securely and filter all the air that is going into your body.

Openings anywhere allow unfiltered, possibly contaminated air into your lungs. Breath close to a mirror and the fogging is from zillions of ultra-minute water vapor particles you are continuously releasing and everyone else is as well. That potentially infectious air stays in the air for a while so when you are distanced from others but walk where they have just passed keep filtering your air.

The following is an abstract published in a reputable American journal, the Annals of Internal Medicine 5 months ago by American authors.
