EDIT: I just realized the link I published was to Facebook and required a log in. I hate that. I have clipped out the content and reposted it ALL below. Apologies for the length, but this is important scientific information that can answer your questions.
And now I’m sure I have started a nationwide run on Selenium supplements!

Lipinski 2015, Ebola and Selenium: How not to catch the 2019 Novel Coronavirus (2019-nCoV)
Today · Public
The only people that can be infected by the 2019-n Coronavirus have less than 98.7 µg/L of Selenium in plasma or serum. Those who have enough Selenium are immune to this and all other enveloped viruses. Selenium can be obtained from Brazil nuts, Selenium pills or Astragalus tea.
This is why only some people get the flu and why others get it infrequently or never at all.
We only found this out in 2015 when Lipinski @ Harvard figured out why some people were immune to Ebola, a fact well documented in medical archives.
Two Brazil nuts a day will do it. An Asia astragalus tea is the primary source of selenium.

2015 Lipinski – Can Selenite Be An Ultimate Inhibitor Of Ebola And Other Viral Infections?
“It is known that the virulence of Ebola and other RNA enveloped viruses involves in the first step their attachment to host cell membranes. Following this initial step the virus enters the target cell cytoplasm by forming hydrophobic spikes that make holes in the membrane lipid bilayer. Formation of such spikes is catalyzed by the reduced form of viral protein disulfide isomerase (PDIred) thus initiating chain of disulfide exchange reactions. Consequently, hydrophobic protein epitopes become exposed, which in the absence of proper chaperones form hydrophobic ‘spikes’ capable of penetrating the host cell membranes.
In this communication evidence is discussed showing that the chain of disulfide exchange events can be inhibited by a small redox molecule – sodium selenite.
It is suggested that this inexpensive and readily available food supplement can be an ultimate inhibitor of Ebola and other enveloped viral infections.”
“other enveloped viral infections” – that’s pretty much all of them.

Dr. Damien Downing, former editor of the Journal of Nutritional and Environmental Medicine, writes: “Swine flu, bird flu, and SARS, all developed in selenium-deficient China. When patients were given selenium, viral mutation rates dropped and immunity improved.”
