Based on matched cohorts - more than half of those with mild COVID had changes in blood chemistry and 1-9 persistent symptoms 6 months after infection. Article: medicalxpress.com/news/2021-05-c…
paper: pubs.acs.org/doi/full/10.10…

Management is something to discuss with a doctor. It's similar to ME, which is also not well understood, need to pace yourself and set achievable targets and take care of general health. Also limiting intake of alcohol, caffeine and not smoking.

Puzzlingly, 30 to 40% report that their condition is significantly improved after vaccination. That could be because of lingering virus in places it can "hide" from your immune system, but so far none found, or a "reset" of the immune system gone wonky. yalemedicine.org/news/vaccines-…

Example story - in this case symptoms flared up after first dose of Pfizer but within a few days of 2nd dose she was much improved.

Researchers are puzzled. They can't find any virus lingering in long haulers - if there it's well hidden. The first example of an ME like illness with a causative agent. So - it might be that by finding out what is going on they get insights into ME too medpagetoday.com/meetingcoverag…

So sad. India states are reluctant to act, some ruled out doing lockdowns, all they are doing is night time curfews, not enough, and in Delhi a 6 day lockdown. Yet every state has exponential growth of COVID and many will be in the same situation as Delhi within a few weeks.

Vaccination will make a huge difference, but India has many weeks to months before it has widespread vaccination. The UK and Israel show where it is headed once there is widespread vaccination. 10 days after 1st dose for vaccines to start working.

Why NFT art is okay. Adding transactions makes no difference to energy use as mining coins happens with or without transactions, also Etherium is in process of upgrade to Eth2, completed by some time in 2022, and after that will have negligible energy use. medium.com/superrare/no-c…

I.e. you use Etherium blockchain, but miners mine Etherium coins with or without fine art transactions, so no increase in mining work. After Etherium "proof of stake" upgrade to Eth2 by 2022, mining has negligible energy use blog.ethereum.org/2014/01/15/sla…

This is about the process of upgrade to the more sustainable Etherium 2 with only a tiny fraction of the energy use of Bitcoin. It uses "proof of stake" rather than "proof of work". I don't understand the details but they have it all worked out. ethereum.org/en/eth2/

BBC article about uneven vaccine rollout - NO MENTION of WHO's requests for last several weeks for UK to stop blocking emergency compulsory licenses to let weaker economies make their own vaccines and drugs, or to swap batches for 10 million early doses.
bbc.co.uk/news/world-562…

This is about the WHO's repeated call to wealthy economes for rapid transfer of COVID vaccine technology to weaker economies to solve bottlenecks & vaccinate world ultrafast - to stop blocking TRIPS or find another solution:
science20.com/robert_walker/…

Short summary: Brazil can make an extra 100 million doses by July through technology transfer with AstraZeneca. We could have many factories like htis for the other vaccines too if wealthy countries stopped blocking TRIPS or found another way to permit it debunkingdoomsday.quora.com/By-this-WTO-ru…

I don't understand why there is such pessimism about zero covid. It's getting politically incorrect to talk about it. Yet 20% of the world already is #ZEROCOVID. quora.com/q/debunkingdoo… Politically correct is #LOWCOVID despite nobody achieving it yet long term for months.

It is not up to the virus. It is up to us. Any country or state can achieve #ZEROCOVID, and join travel bubbles with other #ZEROCOVID countries. At least through to 2022 we have the world divided into #ZEROCOVID and #LOWCOVID and it is a political choice which you join.

But I think #LOWCOVID will be hard to achieve for long periods, months on end, without also achieving #ZEROCOVID because of variants, need for boosters, and if cases aren't falling, they are likely rising. Keep them falling and county, state and country at a time we reach 0.
