This is a paragraph from a May 2020 meta study by the US CDC
Disposable medical masks (also known as surgical masks) are loose-fitting devices that were designed to be worn by medical personnel to protect accidental contamination of patient wounds, and to protect the wearer against splashes or sprays of bodily fluids (36). There is limited evidence for their effectiveness in preventing influenza virus transmission either when worn by the infected person for source control or when worn by uninfected persons to reduce exposure. Our systematic review found no significant effect of face masks on transmission of laboratory-confirmed influenza |

This whole thing has been a Monkey F'ing a Football since the WHO colluded with China...the preparation (why was there a shortage of PPE?) of the CDC for this type of breakout is inexcusable.

There are a number of studies, primarily pre-CV (if you can find them), that put effectiveness at something like 8-12% for the typical blue surgical masks. The fabric masks were found to be negligible. Also there have been recent studies that found that fabric masks also tend to better disperse droplets, essentially dissipating them into smaller droplets that are easier to spread. What Fauci originally said was the truth, anything short of an N95 (worn properly and replaced regularly) is trying to keep out mosquitos with a chain link fence. Sorry but THAT is “trust the science”. A filter that doesn’t have the ability to filter small particles is not a very effective filter.

If there is nothing to transmit, there is no need for masks.
Problem with the Bay Area is 1) how dense the population is and 2) how dense the population is. |

This is a difficul topic because:
1. Places that require them may have low compliance with lower face coverings. 2. Places that do not require them may have a high percentage of wears of lower face coverings 3. Wearing improperly doesn't help and may hurt. I consider the effectiveness when related to the general public to be on par with a little star sticker put on your shirt. There are exceptional circumstances, proper equipment, proper fit, and prolonged face to face. It is rare for me to see when I am out shopping someone without a low face covering despite it not being required. I do see lots of bad habits though. I have to wonder at the emotional toll of not seeing a proper full face smile in public. |

What happened to the flu? It is basically non existent.
https://www.nature.com/articles/d41586-020-03519-3 https://consumer.healthday.com/b-1-15-what-happened-to-the-flu-this-year-2649917471.html https://www.miamiherald.com/news/coronavirus/article248307290.html From the last link: “We are testing thousands of people in our emergency room settings and in our hospitals for a combination of COVID and flu, and we’re essentially seeing no flu,” Dr. Randy Bergen, a flu expert with health care company Kaiser Permanente, told ABC7. “Some weeks we’ll have no cases, others we’ll have maybe one or two.” Health officials in the southern hemisphere — including Australia and South America, where the seasons are reversed — said their flu season was virtually nonexistent while coronavirus cases were spreading like wildfire. The Centers for Disease Control and Prevention says national flu activity “remains lower than usual,” including flu-related hospitalizations, but there’s still time for it to increase in the coming months.

This is something I was wondering early last year.
Flu deaths although estimated rather than actual are quite high. It didn't get attention because most Flu deaths were people on the way out or with other issues that compounded. There is an entirey seperate aspect here - if what we're doing is inneffective against CV19 are face coverings and careful choice of socializing ridding us of flu? It also raises the question, how does CV19 get around under circumstances FLU doesn't? |

SF County has a surprisingly low death rate for an area that's so densely populated. Incidentally, they've had about 900 deaths from drug overdoses since covid started.

From the Mercury News 12/20/20
SAN FRANCISCO — A record 621 people died of drug overdoses in San Francisco so far this year, a staggering number that far outpaces the 173 deaths from COVID-19 the city has seen thus far. |

Death counts are not fair for argument.
Who is counting and the protocols they follow introduce variance. Objectively Frustrating. George Floyd died with CV19 according to the protocol of having a positive test and the time frame from that positive test in which he died. There may be some causes of death where objectivity applies well, but CV19 has not been one of them. |

There's no doubt in my mind that the 173 is a grossly Inflated number and the 621 is accurate

Viruses are smaller than the length of a light wave and therefore cannot be seen without an electron microscope, so it just stands to reason that masks would be ineffective. But wait! Geniuses regularly admit that masks would stop droplets. Well....exhaled viruses are all in droplets. Every one of them. Some droplets are filtered by masks but not all. Many are, however. The research suggests masks are somewhat effective in slowing transmission. Unless your "research" comes from certain sources.
The Western third of Washington State is fairly densely populated and also, predictably, more educated and wealthier and more liberal. The Eastern two thirds is rural. Despite being more sparsely populated, the Eastern two thirds of the state have been the sites of the most ferocious of Covid outbreaks. They don't wear masks much. Refusal to wear masks is pure, unadulterated selfishness. and/or ignorance. I do not leave my property, and we receive no guests. Now is not the time to let one's guard down. Think about this: If everyone were to stay home for 2-4 weeks, the rate of infection would virtually go to zero. If they then practiced mask-wearing and social distancing and avoiding unnecessary exposure, then 4000 Americans would not die each day. If course, it is not practical for everyone to stay home for 2-4 weeks but it is possible for many, and I think we could drive the infection rate way down if we copped some discipline and responsibility.
