COVID-19 — Coronavirus

Looked into the sunlight issue. Here's a paper which focuses directly on the germicidal impact of sunlight and all aspects of the UV spectrum.

I hope you can access. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1280232/

Points I picked up through looking at the impact of sunlight. Some obvious, some definitely not obvious.

  1. At ground level when the Sun is overhead. Sunlight is 44% visible light, 3% ultraviolet.

    Of the UV light that makes it to the ground, 95% is UVA, and 5% UVB with virtually no UVC.

  2. UVC is strongly germicidal but UVB can also kill germs.

  3. UVB is very sensitive to latitude. At high latitude the sunlight travels further through the atmosphere. Surely key to the seasonality of viruses.

  4. The time to destroy 90% of a virus is in the tens of minutes and variable.

  5. Single strand nucleic acids are more sensitive to damage. nCov is single-strand

  6. RNA is less sensitive to damage than DNA based viruses because the molecule most readily damaged by UV light is Thymine and Thymine is not present in RNA. nCov is an RNA virus

  7. The sensitivity to sunlight is linked to the number of base-pairs. I don't know how big the molecular weight of nCov's RNA molecule is compared to other viral RNA but that would be easy to find out.
There's already very strong indications from the distribution of the virus that it's going to be seasonal which brings good news and bad. Good in that it will probably decline rapidly at high latitudes this Summer but bad in that it could easily bounce back as the Sun dips in the Northern sky.
 
Covid test from abbott, fifteen min test that don is using

False results

48% failure rate ,false negatives

Lot more kids in america having the inflamation in their lungs from covid
 
Qatar has now made it law to wear a mask if you leave the house, for whatever reason. So walking the dog and running will be fun in the heat.

My 4 year old granddaughter could have done as good a job.

Probably also not full of people who have the sole intention of undermining the government and disagreeing with everything

Surely not walking your dog in that heat? my dogs won't go out in high temps (hurts their paws) and as for running in high temps it sounds a bit suicidal.
Not yet legal here in Spain but most people here certainly wear a mask though when out of their houses.

Hopefully, opens up the possibility of Covid "passports". As ever though it isn't that simple as its unclear how long these antibodies last and also the current belief is about 40% of younger people don't develop the longer term IgG they are testing Here as it is believed they clear it with their IgA immune system (short term). Which means they may not develop the longer term immunity

What is reassuring is the lack of reinfected healthcare workers suggesting immunity does exist but need to see how they are in 6 months time.

But overall an instant, accurate antibody test is promising!

Up to date article on the potential effects of survivors medium term health on cv19 and very interesting analysis of monitoring that happened during the subsequent years to the initial 2003 SARS survivors, not very positive follow up data on those who survived unfortunately :-(

Also think this section needs highlighting for future consideration on policy seeing as we are always behind the curve on the science.

There is some hope: Early intervention could play a role in longer-term outcomes of coronavirus patients, said Ivan Hung, a professor of medicine at the University of Hong Kong. Hung said in April that 90% of about 200 discharged patients he oversaw at a clinic at one of the city’s hospitals appear to be making a full recovery a month out.

He attributed the success to Hong Kong’s “early diagnosis and early treatment” of patients, which leaves the virus with less time to wreak havoc on the body.

That’s true of many/most viruses.

There’s a pertinent snippet in this article:
https://www.nature.com/articles/s41598-017-17497-6
where is calls influenza infection in the lungs a “lung injury”.

Wherever a virus/bacteria/fungi affects a part of the body, they cause an injury to the cells or even the full organ in that part of the body. As anyone who’s had a physical muscle or bone injury before, you know that, often, you never fully recover from it.

You said put to bed,clearly a look around around the world and research doesn't bear that out,it should slow but it will still be here and still spreading and still killing,social distancing will have to continue just the same as now,you forget this is a brand new virus that has its own identity and complete with surprises

So far you have told people they are definately immune and for how long,in capitals i think it was and that antibody tests have already been used and good enough for clinical use,i will let you off masks although you over egg them a lot

Don't lead people up the wrong path,everyone wants hope but bad info is worse than no info

he's not posting bad info.

thats been confirmed by the number 1 specialist in Korea on Coronavirus.

I watched the same video yesterday
