Contract tracing hasn't worked at scale anywhere. It's a nice idea conceptually, but the problem is psychological. People stop caring about tracing when 98% of all trace connections are false positives. If a person is infectious for a week and the r0 is around 1 then only 1 person of all the people they've been in contact with will actually contract the virus on average. The other 50+ people, assuming they can even b…

Contact tracing is working extremely well here in New South Wales. But we have very low incidence of virus in the community, sufficient to get useful early warnings when DNA analysis picks up virus in the sewage system. So once you're down to low levels of incidence in the community, given a robust well organised system, efficient contact tracing does prevent the virus from spreading in the community unchecked.

Reference if anyone cares: https://www.abc.net.au/news/2020-09-08/why-pm-says-nsw-is-go...

They have done very good at tracking and locking down the few cases that get out, even with very low mask use in the general community based on what I've seen. People were sensible when it mattered most.

You have to love the morons who downvoted you when it's painfully obvious that eating meat is the cause of so much health and environmental issues on the planet. For most people here, it's not even that big a deal to switch to a plant-based diet or mostly plant-based diet. Better to adapt now rather when the double or triple digit taxes start coming for our meat-eating asses.

The true origin isn’t known. Maybe escaped from a lab, we don't know yet.

And maybe it was aliens, we don't know yet. But it's not really helpful to suggest random theories without a shred of evidence on the off-chance that they might be accurate, because that rabbit hole has no bottom.

Yet another reason to move to a plant-based lifestyle. Covid came from some folks in China using exotic animals for some purpose. Now a new variant seems inevitable from animal populations. Is it worth the burgers and coats?

You're being downvoted for no good reason. Mass farming is what brought us here. This will keep happening, unless we change our behavior.

Wet markets and mass farming are two different beasts

I think we can eradicate it by contact tracing. With 90% efficiency it will be extremely tough for the virus to spread. For any new cases you simply test everyone in the vicinity of the infected person. But I don't think even that will be necessary. 90% efficiency reduces R so much, it will probably die out on its own. The real problem is mutations that are not covered by the vaccine. If it mutates as efficiently as…

It worked really, really well in South Korea and New Zealand. Besides, that's just your opinion and epidemiologists agree that contract tracing plays a significant role in reducing the spread of COVID.

"it will likely be months before doses start going" Where do you get that it will take "months" between emergency approval and actual vaccinations? The communications out of the leading vaccine teams clearly state otherwise.

>Where do you get that it will take "months" between emergency approval and actual vaccinations Because this is a press release from a corporation with a vested interest in being "first" and not an approval by the FDA.

Oh, so just blanket cynicism with no evidence, got it.

It's worked in Australia.

This is only a superficial solution to the cause of these zoonotic diseases, which is overpopulation. The problem is that with 7bil people disease will spread with increasing frequency, and areas of super population growth like Africa and India will suffer the most.

But because no vaccine for any coronavirus had ever been invented, this new vaccine and the new techniques used to make it must be celebrated as a technological breakthrough. Possibly the greatest medical breakthrough since the 19th century. Possibly Nobel prize winning material.

Good: + ~90% of individuals achieve immunity. + no significant side-effects. Not so good: - two doses needed, 3 weeks apart, immunity after one month from first dose. Slow rollout. - -80C storage and transport needed. Challenging, but doable in developed countries, but still may slow down mass rollout. Not feasible in many developing countries. I still wonder about long-term immunity. Anyone can share any insight?

How do we know that there are no significant long-term side-effects? These vaccines seem to be developed so quickly while others take years or even decades... I do not know if this is irrational fear, but I fear that this is rushed and there might be potentially serious side-effects that are missed. Why am I being down-voted? Is it really of no concern?
