My assessment of coronavirus transmission chances

My assessment: TB & Measles are much more communicable, and coronavirus is like the flu, but coronavirus is randomly more deadly than any of them. Also, coronavirus, if allowed to fester, may well mutate into even more deadly forms. Thus we have a public-health incentive to vaccinate and prevent its spread. And just like grandma said, fresh air is important!

Following quote is from a recent detailed article in Wired magazine, by Megan Molteni, mostly about the curious specification of droplet vs. airborne transmission, and the 1940s era of scientific progressivism not wanting to credit miasma! It turns out that miasma -- in the form of tiny airborne pollutants -- is really a thing.

...airborne transmission is both more complicated and less scary than once believed. SARS-CoV-2, like many respiratory diseases, is airborne, but not wildly so. It isn’t like measles, which is so contagious it infects 90 percent of susceptible people exposed to someone with the virus. And the evidence hasn’t shown that the coronavirus often infects people over long distances. Or in well-ventilated spaces. The virus spreads most effectively in the immediate vicinity of a contagious person.

My COVID journey, finally

11oct22 story of Covid: I flew to Des Moines for a mini-reunion of Thomas cousins; flew back on Monday the 3rd. I did not wear a mask. Evidently I should have worn a mask, as I later came down with Covid. The infection could come from anywhere, typically airborne virus shed by someone in the communicable phase of the disease. Throughout my airport and flight experience was quite calm and uneventful, so my guess is the most likely vector for the virus was the deplaning time – people are really eager to get out, they are talking, pressing close together, straining to grab bags from the overhead compartment and coordinate with their partners, thus breathing heavily. Very few people wore a mask. I do not remember anyone coughing or sniffling or breathing heavily around me, but that deplaning process is always rather hectic. I did not press to go quickly, but I did not want to delay my windowside seatmate, so I joined the crowd. As it was, when I arrived at baggage claim, my suit

Montpellier

[23mar22] Another walking day: to the A rc de Triomphe , passing through quaint quiet attractive old neighborhoods, particularly the P lace de Marché des Fleurs. Arc de Triomphe is spectacular, next to an equally impressive Palais de Justice , and the Promenade de Peyrou that has a great view of the surrounding hills and the aqueduct built by Peyrou to supply the city's fountains. The Jardin des Plantes – oldest botanical garden in Europe – opens at noon, so we walk around to the Cathedral St.Etienne, with its obscure side entrance, but huge interior space, really huge and rather stark, in keeping with its 13 th century origin – though of course several later kings and bishops added chapels, stained-glass, and organ. While there, the organ started up, providing appropriate sonic accompaniment to the surroundings (ref. My video). We return to the garden to await its opening, chatting with some Chicago tourists (go Bears!). The garden is very nice place for sauntering, and

Riding the Bus often

From 201010 Saudi scenes It is ironic that this land of cheap gasoline has so much group transport -- buses. From 201010 Saudi scenes Our housing compound has a Toyota-Coaster bus that takes some to/from school (we usually go earlier and return later, on a similar bus that the school provides). Driver Yahya takes residents on the 90-minute trip down to the Big City shopping every Thursday morning. The above picture shows our group one Thursday, usually going to Ikea or the new Lulu's Hypermarket , or the Dhahran Mall. Coleman rides a different bus every day to and from school -- usually 100 minutes there, 80 minutes back. His bus is evidently an old tourist bus, usually comfortable but a bit dusty. The air-conditioning usually works too well. I've ridden it with him several times, to attend business meetings at the district office. From 201010 Saudi scenes There he is, at 5:45am every morning, at the start of the bus run. Fortunately only about 20 students
