Masks: Double, Counterfeit, Ungettable & Unsellable

It's been a big week for mask news.  I continue to see stories like this on my news feed, promoting everything making a mask good except its filtration ability. Experts are saying we really should be thinking more about that, with the new, more contagious mutations and all. Government standards for masks are on the way and may help people make better decisions.

One way to up your mask game is by double-masking.  The CDC is now recommending it. A test done here at Corona-zona Labs found that double-masking does improve leakage, though not nearly as well as a mask fitter.

Another thing you can do is get an N95 mask. The CDC has not changed its recommendation that N95s should only be worn by medical professionals.  This is because of a supposed shortage.  I say "supposed," because this company says it has 30 million it made but can't sell.

If you are looking for N95, beware of fakes.  The feds have conducted over 1000 raids in an investigation of bogus 3M N95 masks, marked to look just like the real thing. Fakes have made their way into hospitals too.  

Caveat emptor! If you're shopping, here are some tips for determining if your N95 is the real thing or a fake.

Looks Like Immune Responses are Enduring After All

Image
 For some time, public health officials have fretted about whether immunity to COVID-19, acquired via infection or vaccination would stick.  Studies showed rapid declines in antibodies during recovery from infection and thereafter . It turns out that this concern was overblown. A study just released says bone marrow plasma cells are a persistent source of protective antibodies, and that "circulating resting memory B cells directed against the S protein were detected in the convalescent individuals."   Another study , yet to be reviewed, suggests that vaccines boost this effect. In fact, some are suggesting this situation this could actually mean  lifetime immunity .   Whether the same thing happens with vaccination is not clear. Most estimates suggest that vaccine immunity will last about a year . More pessimistic estimates putting the protection period at six months .  The possible shorter time frame, plus the appearance of the new variants, have the vaccine makers working

Another One Bites the Dust

Hi all. Stepping out of retirement for a moment to say that the day has finally arrived. After four years of successfully avoiding COVID-19 infection I had a positive test yesterday. Symptoms are very mild—I've had worse colds. The provider at urgent care said almost all the cases they are seeing are the same. Mild symptoms may also be due to the fact that I had the original vaccine then the two boosters. All this time I thought I might be a NOVID —one of those people who never get the bug. But no, it must have been my assiduous mask wearing and avoidance of high-risk situations when things were bad. So here's double middle fingers to all the kooks who think masks don't work (I've not been wearing masks for months now). I don't know what variant I have but it's likely JN.1. It is said to be extraordinarily contagious and accounts for 60% of cases worldwide . It also tends to produce mild infections like the one I have.  This article claims that right now every

AZ Pandemic Numbers Summary for the Seven Days Ending November 9: Everything is Going South

Image
Here are the Arizona pandemic numbers and graph of statewide cases for the seven day period ending yesterday: Well this isn't good. The lull seems to be over. Virtually every number is up, both over a week and over four weeks. The most worrisome is hospital beds, which have been steadily trending up over the last several weeks.  Wastewater signals are all up except Tempe (dashboard is up again) which after going up last week (from 41 to 100) decreased by about 10%. The increases are worrisome because the latest data from ASU's Lim Lab (last updated October 31), where they sequence PCR samples to identify variants, shows that only about 46% of sequences showed BA.5. That is one of the Omicron variants the new bivalent vaccine was designed to protect against.  All the rest of the samples are BA.2.75 (7.7%), which I flagged several weeks ago, and BQ,1.1 (15.4%), and BQ.1 (30.8%), both of which I blogged about a couple weeks ago.  Those, new research confirms , are much more lik
