I’ve been traveling a LOT recently and just skipped last week’s update. Sorry for the long delay.
The US continues a slow trend upward in new confirmed cases. According to endcoronavirus, most of these new cases are arising in the Northern states, although the upward trend seems to be creeping south. This seems to confirm my suspicion that the new uptick in cases is caused by colder weather, and people being indoors together more often. If this suspicion is correct, we may be in for a long broad 3rd wave of cases this winter. You may remember that the Southern states (California all the way to Florida) drove new cases this summer. During the summer of course, people in Southern states tend be indoors with their air conditioners more often. This is my theory for the time being.
After the end of the 2nd wave, California is experiencing a persistent 3000 new confirmed cases a day, and San Diego County has a persistent 300 new confirmed cases a day. Unfortunately, I’m firmly convinced at this point that COVID may be with us at least until next Spring. As you know if you’ve been reading my posts, I think we will need to adapt to this situation, and open up our economy and normal life as much as possible, while still taking precautions.
As I’ve mentioned before, I am doing a lot of traveling these days, and get tested almost every week, and I’m always negative so far. I use air travel and go into all kinds of gas stations and stores. I do the following:
1) Wear a mask or face covering in public. Avoid places with unmasked people.
2) Keep 6 ft away from others. (I basically ignore this one if other precautions are in place, especially on an airplane!)
3) Avoid indoor gatherings, especially ones in which singing or shouting is likely.
4) Small outdoor gatherings are fine, even without masks, if everyone maintains a distance. Have guests bring their own food.
5) While many restaurants are open for limited indoor seating, I personally am still not comfortable eating indoors at a restaurant. I enjoy eating outdoors at restaurants, however.
6) Wear an N95 or KN95 mask when going to more high risk areas like airports or public areas where people may gather. These masks are rated to filter out 95% of viral particles. In my opinion, surgical masks and especially neck gators are nearly worthless in these settings.
7) I never take my mask off on the plane, and find an isolate spot in the airport to eat or drink on layovers.
Voting: If you haven’t heard, there is an election coming up. As with many issues, mail-in voting has become a politicized issue. The New York Times recently had a story expressing reservations about mail in voting, claiming that mail in ballots are more likely to be disqualified than in person voting. This is because filling out and mailing in these ballots can be complicated and prone to errors that disqualify these ballots. Some stories even claim that people have been sanitizing their ballots, ruining the ink and disqualifying be ballot. It is therefore my recommendation that everyone vote in person if possible. Follow the above precautions, and I’m confident you can do so safely. Dr. Fauci claims that in-person voting is safe if proper precautions are taken.
Reinfection: There is a recently published study of a confirmed case of re-infection in an American man. Apparently, this is the first confirmed and well characterized case in the US, although there have been other suspected cases. His symptoms were more severe with the second case, suggesting that my fears of ADE may be warranted. However, there have been only 22 confirmed cases of reinfection world wide, so it’s still apparently a very rare phenomena. The paper also states the 2nd infecting strain is distinct from the first, consistent with the ADE model.
The paper suggests that there may have been dozens of circulating strains since the beginning of the pandemic. While this case of re-infection appears consistent with ADE, the rarity of the re-infection phenomena along with the many circulating strains suggests that ADE, while theoretically possible, may not have large real-world significance.
New 3D structure: Last, for those of you who want a deep dive, the New York Times has a nice story with a collection of 3D structures of the virus from different sources.
Don’t fear, but be smart!
