And stillbirths from changes in the placenta "the ventilator of the fetus".

https://www.healio.com/news/primary-car ... th-covid19
The major thing that we’re talking about are problems in the category of what’s called maternal vascular malperfusion. The placenta is the ventilator of the fetus. It is the first organ to form, and it does a lot of the functions for the fetus that other organs do for us. The fetus — through the umbilical cord — sends a large volume of blood into the placenta. The mother — through the vessels in the uterus — sends blood into the placenta. Those circulations don’t come into contact, but they’re set very close together. And so, you have exchange of oxygen and nutrients from the mother, and waste and carbon dioxide from the fetus. Maternal vascular malperfusion is a group of problems that we see in the placenta that deal with getting the blood from the mother into the placenta. More specifically, the problems we see in COVID-19 patients are with maternal blood vessels. Those vessels are normally wide and stay open, and we see some of the vessels are either more constrictive or they have muscle on them that will cause them to constrict. The other thing we see is actual injuries to those blood vessels — something that’s called atherosis and fibrinoid necrosis —where the wall of the blood vessel is injured, and you have an accumulation of blood clots and inflammatory cells. In general, maternal vascular malperfusion lesions on the placenta are things that we expect to see when moms have preeclampsia or other hypertensive conditions. In terms of consequences to the fetus, maternal vascular malperfusion changes are one of the sets of changes that we tend to see in stillbirths. That’s something, obviously, that we’re worried about a great deal. Some of the maternal vascular malperfusion changes have been associated with cerebral palsy, although not the blood vessel injury that we see in our study. These changes are actually associated with cardiovascular disease in the mothers long term. In the patients in our study, there was one patient who had gestational hypertension — somebody who was not previously hypertensive and who became hypertensive in pregnancy. Otherwise, none of our patients had preeclampsia or gestational hypertension, which makes us think that these changes are more related to the virus.

I hope Health Canada will consider this idea. There is risk of false sense of security when result is negative. But with clear label and education of the purpose of the test, this can be a valuable tool to prevent COVID spread, especially in public service sector and schools.

People around you may have weaken immune system (or live with one). Wear a mask in indoor settings if you have cold symptoms.

I like the fact that even if there was a vaccine, vaccines appear to be less effective in the overweight and obese in particular (observed in vaccines for many diseases).

That will really limit effectiveness, even if inoculation rates were widespread down south, and not much better in many anglo countries.

If nothing else, it could help destroy the anglo-american led snack food industry (or not).

CDC released detail of 2020-2021 flu vaccine, same as what recommended by World Health Organization, so should be same as what we will get here.

This could be the first confirmed re-infection of COVID-19 (by two different strains of SARS-CoV-2). This is not surprising, what's important is how the immune system response to the second infection. And from this particular case, the prospect of COVID vaccination is still promising. The real take away is we now can confirm the idea of "immunization passport" is flawed and should not be considered.

A few more "reinfection" reported. Reno's case is concerning because the patient's second COVID episode was more severe than his first. The other concern is these reinfections happened on younger population. I still believe vaccine will be the answer but looks like this will be a long battle.

Note the Harvard epidemiologist Dr. Mina commented in above Statenews article is the same person who advocates the low cost paper test strip for COVID-19 that I talked about a month ago.

HK study finds COVID-19 stool tests may be more effective for infants

Three patients continued to display active viral infection up to six days after clearance of the virus from their respiratory samples.
