1. I used a cloth mask I made myself with disposable lab coat material.2. I used blood agar.3. The plate on the right looks "old" or "stale" because of the growth. Some of the organisms on this plate are alpha hemolytic, meaning they partially hemolyze blood. The agar itself is made with 5% sheep's blood, so when it's partially hemolyzed, it turns a dark green color.4. As for the growth, it's mostly viridans strep, staph species (not staph aureus), neisseria species, and corynebacterium. Pretty normal oral flora.5. I realize that viruses are 1,000 times smaller than bacteria. The point of the masks is to prevent droplet spread, which carry bacteria as well as viruses.

basic knowledge of droplet kinetics, dictate that wearing masks most likely provides a small benefit that, considered at the scale of all of american society, probably translates to many lives saved.

link from another M.D. friend:
After evidence revealed that airborne transmission by asymptomatic individuals might be a key driver in the global spread of COVID-19, the WHO recommended universal use of face masks. Masks provide a critical barrier, reducing the number of infectious viruses in exhaled breath, especially of asymptomatic people and those with mild symptoms (12) (see the figure). Surgical mask material reduces the likelihood and severity of COVID-19 by substantially reducing airborne viral concentrations (13). Masks also protect uninfected individuals from SARS-CoV-2 aerosols (12, 13). Thus, it is particularly important to wear masks in locations with conditions that can accumulate high concentrations of viruses, such as health care settings, airplanes, restaurants, and other crowded places with reduced ventilation. The aerosol filtering efficiency of different materials, thicknesses, and layers used in properly fitted homemade masks was recently found to be similar to that of the medical masks that were tested (14). Thus, the option of universal masking is no longer held back by shortages.[...]
Aerosol transmission of viruses must be acknowledged as a key factor leading to the spread of infectious respiratory diseases. Evidence suggests that SARS-CoV-2 is silently spreading in aerosols exhaled by highly contagious infected individuals with no symptoms. Owing to their smaller size, aerosols may lead to higher severity of COVID-19 because virus-containing aerosols penetrate more deeply into the lungs (10). It is essential that control measures be introduced to reduce aerosol transmission.

More than 100 scientists and clinicians have questioned the authenticity of a massive hospital database that was the basis for an influential paper published last week that suggested the use of chloroquine and hydroxychloroquine to treat people with Covid-19 did not help and may have increased the risk of abnormal heart rhythms and death.In an open letter addressed to The Lancet’s editor, Richard Horton, and the paper’s authors, they asked the journal to provide details about the provenance of the data and called for the study to be independently validated by the World Health Organization or another institution.

xpost seriously - even if the study was flawed, there isn't a (non-discredited) study which shows that it IS.
and my friend who takes a maintenance prescription for HCQ actually had his latest RX reduced to 30 pills instead of 90 as his carrier cited there was a shortage in availability, presumably due to the extra people taking it for COVID-19.

If the one human trial is a good indicator, the efficacy of remdesivir against COVID-19 is very modest. According to that WaPo article, the 'break even' cost for the patent-holding company could be around $1/dose. The eventual price should reflect those two factors... but will it?

so now researchers have figured out how COVID-19 causes so many different symptoms in different organs: It is a disease of the blood vessels. They hope that this will point toward possible treatments.

Toward the end:
This hypothesis provides a rationale for therapies to stabilise the endothelium while tackling viral replication, particularly with anti-inflammatory anti-cytokine drugs, ACE inhibitors, and statins.
Presumably, since this article was listed as published in late April, this treatment strategy has been attempted in some cases and some preliminary data collected, even if there have not been any trials. I wonder how its going.

The plan is to manufacture doses of the vaccine even before it is clear whether the vaccines work, making close to 100 million doses by November or December, Fauci said. That’s so if it does work, it can be deployed quickly.

I saw that after I posted--he still sounds optimistic.
“Which tells us, that if the body is capable of making an immune response to clear the virus of natural infection, that’s a pretty good proof of concept,” Fauci said. “Having said that, there is never a guarantee.”
He was a 12-18 months person early on with regards to a vaccine, so early 2021 almost fits that timeline--maybe 2-3 months ahead.

"The US should have 100 million doses of one candidate Covid-19 vaccine by the end of the year, Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases (NIAID) and a member of the White House coronavirus task force, said Tuesday.
“Then, by the beginning of 2021, we hope to have a couple hundred million doses,” Fauci said during a live question and answer session with the Journal of the American Medical Association.

Meanwhile, I think I saw (and while the exact numbers may be off the gist remains the same) that after a bunch of contact tracing in Hong Kong, they determined that a small handful of super-spreader events accounted for a huge number of cases, but of those who contracted Covid, 70% did not pass it along. For some reason certain people just spread the fuck out of this.
