Covid notes: Hydrochloroquin, UV and ozone might help too

so hydroxychloroquin works?

the good doctor discusses the studies in detail. 

not a miracle cure, but the Belgium study suggests that if you use it early and correctly, the mortality is lowered 30 percent. 

The dosage and timing is the key:
the problem seems to be that they gave a very high dosage and that is why there were so many side effects. (italics mine).

and the good doctor wonders why all those experts used the wrong dosage... i.e. why did the Brits and WHO get the dosage wrong?



listen to the whole discussion if you want the details.

A Yale Epidemiologist also noted that the ability of the drug to cut the fatality rate

one is reminded of stories that some of the high mortality of the 1918 influenza epidemic was due to overdose of aspirin...-----------------------

update: more discussion here: and also discusses the possibility of reinfection, and what it means for a vaccine stopping the epidemic. Note: The reinfection was from a different version of the virus, and at least one person had a bad immune system.

Another related topic: one wonders about the slowness by the experts in checking out the old fashioned methods to stop viral spread.

Instapundit links to an article about UV light stopping the virus, something I noted a couple of months ago since we still have such UV lights in our hospitals here over doorways (presumably to stop TB spread) and we used to have them in hospitals back when I started working in hospitals back in the 1960s.

however, to kill covid you need a special frequency and high dosage: this will sterilize surfaces, but can cause sunburn and eye damage if used in high dosages in public areas.

But you know, my hepa air filter has UV light inside it to kill mold etc... so I wonder, so will adding UV light, maybe in higher doses than being used now, to air conditioners and heaters that circulate the air kill the virus so that indoor spread will be limited?

this is important, since air conditioners/ air flow indoors are known reasons that the virus spread inside buildings.

ChicagoTrib discusses here.



The best combination to cut down the chances of spreading the virus is a HEPA filter and a UV light, Myers said. HEPA filters, used in hospitals, can remove 99.7% of particles as small as 0.01 micron. That’s efficient enough to capture the COVID-19 virus, which is said to have particles approximately 0.125 micron in size.


and what about ozone? LINK link2

not my area of expertise but again might help in surface sterilization. 


Finally, there will be an investigation into the nursing home kerfuffle, where governors ordered recovering (but still infectious) Covid patients back into nursing homes.

nothing will come from it, of course, because the regulations said it was okay, and the governors were only following the regulations: (italics mine).


The experts who wrote the regulations insisted that infection wouldn't spread if you had adequate PPE used by personnel correctly and you isolated the patient.

The problem? 

Reality. 

Nursing homes often lacked PPE, but the bigger problem is that many are understaffed (money money money) and often the number of staff is estimated for ordinary patients, not for such isolation which takes caregiver's time. 

And I won't even go into the poor quality of staff in many nursing homes (because it pays lousy for hard work, often the staff is not high quality. Duh).

One does not expect a governor to know such things, so one doubts they will be charged because hey, they were only following regulations devised by experts.

However, since the Pennsylvania public health expert who agreed to the policy took her mom out of a nursing home and placed her mom into a hotel for safety reasons, one does suspect that there were some in the state governments who knew the advice was faulty but, this being government, just went along with the policy because hey, if you make waves you get harassed out of your jobs (been there, done that, long story).

and as I noted yesterday: Sweden had the same policy and many of their deaths were also in nursing homes.

so the problem was not just in the USA...
