After surveying many YouTube videos for face masks, I condluded that I could design a better cloth mask. Many designs I viewed did not seal the gap between the mask and cheek bones — particularly when worn by someone who has a prominent nose, like me.Continue reading
There is no way to “see” where the COVID-19 virus is, just as we can’t see other microbes. Healthcare professionals learn habits called sterile technique to minimize the chance of transferring invisible microbes from one patient to another, or to an open surgical wound. In the following video, the doctor demonstrates the use of sterile technique to ensure that the goods you bring into your home don’t carry and shed the virus.Continue reading
Are we so immersed in our throw-away culture that we have forgotten how to reuse scarce items? As the COVID-19 pandemic exhausts supplies of basic protective gear some workers are going without masks and protective gear because all that’s available is disposable. But that may not be necessary.
An ordinary clothes dryer set on high should be hot enough to destroy viruses on contaminated clothing. An infra-red thermometer would allow you to check the temperature inside the dryer. Before relying on this, get an expert opinion. That said, wouldn’t it be better to use the dryer than to simply re-use potentially contaminated gear or go without?
An ordinary pressure cooker develops 10 to 15psi steam at 240 to 250 degrees Fahrenheit. Objects suspended in a wire basket or colander would be steamed at this temperature.
Stanford has tested various methods for sanitizing disposable masks for reuse. They don’t recommend any method, possibly for liability reasons. They have determined that steam sterilization destroys the effectiveness of N-95 masks.Continue reading
Probably the most common sanitizing solution is one tablespoon of regular strength bleach (unscented) in one gallon of warm to hot water (70 to 110 degrees). This solution degrades over 24 hours and should be made fresh for each use.Continue reading
This is my take on the attitudes and actions that are prudent now and for the coming months of widespread contagion. First, adhere to the guidelines of the CDC.Continue reading
Here is an excellent overview by Johns Hopkins…
In my original post under this title, I may have been guilty of contributing to the “Epidemic of Armchair Epidemiology” described in the article linked below.

I’m posting the following links with a caveat: it’s opinion, it’s the author’s viewpoint. Although it appears that the author has done his homework, the article was published in Medium, which is an open forum not subject to editorial scrutiny and vetting. It’s not peer-reviewed science and may not stand up to rigorous scrutiny. When you open the article you will see this statement: “Anyone can publish on Medium per our Policies, but we don’t fact-check every story. For more info about the coronavirus, see cdc.gov.”Continue reading
Misinformation is circulating on social media and in viral emails. This article provides links to credible sources for information.
Why “Social Distancing” is critical.
The Washington Post published three graphic simulations that clarify what a strategy of social distancing does to preserve our ability to cope with a pandemic. Slowing the spread flattens the peak load on medical facilities so that severely ill people can be treated effectively thus reducing fatalities. Reducing the percentage of people out sick on any given day is another benefit of flattening the peak of an outbreak.

Here is the abstract of a new study. It concludes that COVID-19 is much more contagious than we believed.
“This is the first major medical voice to express this opinion. Dr. Shapiro is not just expressing a personal opinion, but that of the largest academic medical system in the country…over 40 hospitals (3 in Italy), 36 senior living facilities, #5 in NIH funded research, and 3.8 million insured lives in its health plans. We have a lot of data.

He is careful not to claim this applies to already heavily infected areas on the east coast.” — Mark Laskow, Key West
Here is a review of free alternatives to the pricy Adobe subscription line. Though I still rely on my vintage Creative Suite 5.5, the state of the art marches on and some of these offerings have advantages that interest me.
This interview of a veteran reporter who has studied epidemics and knows the experts well reveals the scientific effort to fight COVID-19.
Here is the best article I have seen so far on how to make a DIY face mask. It discusses not only how to make the mask, but also the best materials and design features. It also ponders the limitations to protection. But most important, it describes how you should don and remove the mask to avoid contaminating your face and defeating the whole purpose of wearing a mask in the first place.
There is one design feature missing from the masks described here: they leave an air gap on each side of the wearer’s nose. Commercial masks often have a soft metal wire embedded in the upper edge that is easily shaped to close the gaps and achieve a better seal.Continue reading
Here are some resources for getting more out of the free Zoom meetings service. The first is an independently produced video that’s quite detailed (20 minutes). Laptop users can pause the video by pressing the spacebar.
The official training videos from Zoom.us are just 3 or so minutes and each deals with a particular feature.
Gates’ Foundation has been a major funder and a leader in the response to global epidemics for years, most notably Ebola. Now they are working on COVID-19. What is less well known is the fact that Bill Gates did a TED talk warning of the danger of just the sort of pandemic we now face. Here are both talks.
And his warning of March 2015 …
Our government did not see this disaster coming and defunded and downsized the departments that were responsible for ensuring preparedness. These talks demonstrate that those responsible could have known and should have been ready. Failure is always an orphan.
Trevor Noah interviews Gates on fighting the pandemic.
