A 25-year-old resident of Reno, Nevada was infected with the pandemic coronavirus, SARS-CoV-2, two times, about 48-days apart, with the second infection causing a more severe case of COVID-19 than the first and requiring hospitalization and oxygen support.
That's according to a draft study, led by researchers at the University of Nevada and posted online. The study has not been published by a scientific journal and has not been peer-reviewed. Still, it drew quick attention from researchers, who have been examining data from the first confirmed case of a SARS-CoV-2 reinfection, reported earlier this week.

Amid the more than 24.5 million cases worldwide, it is completely expected to find some recovered patients who are not completely protected by their immune responses and are thus vulnerable to reinfection.The big question is: how common is this scenario?

I'd only add get a pulse oximeter and if you feel sick and your spO2 starts dropping do not wait for weeks before getting supplemental oxygen. And the best way to do that is probably hyperbaric chambers. Especially since its now being reported that methemoglbin levels are high and total hemoglobin levels are low. HBOT bypasses hemoglobin and forces the oxygen to dissolve directly in the blood.

We've known all this since mid-April (some since February). Everyone who has died since then has died from inept medical treatment.

My biggest frustration, mostly with "news" media: so much talk and stories and very little useful information. Thank you for useful information.
Q: do you know- what is the specific mechanism of death due to COVID-19??
The best I've been able to glean through all the noise is low blood O2 due to lung inflammation.

ARDS or blood clots, afaik.

Yes, thanks, and that's the general symptom diagnosis. I was wondering if anyone has more detailed specifics about the underlying mechanism.
AFAIK it's lung inflammation due to overactive immune response (in the lungs), and the dexamethasone steroid treatment is radically helping:

It's not without downsides, but this seems to be an improved medication regimen:
