The politics of Covid is astounding.
For those of you who question the effectiveness of masks...oh my I am a dentist. We have been wearing masks 100% of the time in our offices from the beginning. We require all patients/delivery persons/anyone who enters our office to be wearing a mask that covers BOTH their mouth and nose. No...we do not allow mouth shields or face shields in place of a mask. They are not the same thing at all. From January 2020 through September 2020, less than 1% of all people who work in a dental office have tested positive for Covid. A dental office is probably the most dangerous place you could be with regards to an airborne infectious particle. Our handpieces blow air in the mouth which ejects the oral contents into the surrounding air in a mist. Our instuments to clean teeth (ultrasonic scalers) create the finest of mists. Yet, less than 1% have tested positive. Remember, all these people spend most of their time outside of the dental office so it speaks well of their behaviour outside of the office also. I took a walk today in my town's park. Here in California we are having the most significant of all Covid surges. My local hospitals have ICUs that are 100+% full. The dog park had more people than I have seen in many months. AND...there were less masks inside that dog park than inside my car. That is why we are having this problem. Now, let us talk about soaring. |

Now, tell me again how effective those cheap, throw-away masks are. Tom |

JJ Yes John, those were the days, they quarantined the sick. 70 or more years ago *almost everybody* got mumps, measles and (often) scarlet fever. Obviously, since there were no vaccines. If you were male, you wanted to get mumps before puberty because getting it later was very nasty and could make you sterile - anmd its not good for women either. Now we have vaccines against all of these and the MMR shot deals with the first two (both varieties of measles), so people are forgetting how nasty these were. Given that mumps can have such bad after effects, and measles isn't pleasant either, it makes you wonder whether antivaxers have any idea of the risks they're exposing their kids to. Disclaimer: I have no medical training, but was a kid when measles, mumps and scarlet fever were common, so of course everybody knew about them, their symptoms and after-effects. -- -- Martin | martin at Gregorie | gregorie dot org |

Everyone, including scientists, were ignorant of its biology, best anti-infective measures, and best treatment a year ago.. Facts, through research, have been steadily accumulating. Sadly, opinions are often strongly held, even by "authorities", that are dissonant with fact. The discipline of practicing clinical medicine is that one quickly learns that using opinion instead of fact to treat patients is a disaster for the patient, which makes us cautious. Most people are not faced continually with this potentially catastrophic error-checking by nature, so opinions float free. DrDan Johnson |
