French woman who tested positive for Covid: Detailed timeline announced

For current infection, the standard PCR swab test, ie. long cotton bud on back of throat and up each nostril. Has a reported ~2% false -ve rate and a reported ~5% false +ve rate.

 

I think the shonky test kits were the antibody ones that test blood for past infection.

 

A 5% false positive rate may not sound excessive but it depends how the test is being used.

 

If it is used for testing on an apparently high risk individual where any positive result will mean further tests are done thereby reducing the margin of error that's ok.

 

But when used for population wide testing (such as the UK is doing with PCR) and the expected rate of real positives may be as low as 1%, then a false positive rate of 5% means that of all positive results from that testing, 20% will be real and 80% will be false. That renders the resulting data worthless.

The woman was Covid free after state qurantine, where did she get the infection ? yes in Thailand.   Thai people is not tested regulary, the covid virus can be in the society without anybody

You are basing your conclusions on a single case while there's data on tens of million cases.   The accuracy of tests and the length of incubation periods were questionable early on, it's no

Only the foreigners; returning Thais do not need a pre-flight Covid test. Doesn’t make sense......

This is strange....

 

How did a tourist come in on 30 Sept when it is supposed to be closed for all tourists?

 

........

 

Not a tourist? She was probably a family member of the husband who has a suitable visa OR she has a suitable visa and the husband was family member. What caught my eye was they visited the Embassy immediately after ASQ, a simple tourist or even long stayer would not do that, so I assume it was "business" related in some way.

Regarding the French lady, there are a number of possibilities: 

- She contracted Covid-19 from elsewhere, as nothing is water tight, even quarantine

- She has a regular cold and exhibits symptoms, the Covid-19 test was a false positive

- She has carried Covid-19 for a few weeks (asymptomatic), she is one of the extremely rare cases where Covid-19 developed outside of the usual window

 

 

 

 

 

 

 

 

add to the possibilities

 

regarding that the incubation period can be up to 27 days, she could have contracted the Virus in France, way before her flight.

 

The requirement to show a Covid-19 PCR test with a minimum age of 72 hours prior to boarding the flight, could have left an open window between the test and the actual boarding, during which she could have gotten infected.

 

It then only takes a few flaws to occur with the subsequent 2 more tests during the quarantine, to slip through the screens

Theres a rumour that she is not French but a dual Thai national but I find it hard to believe that the propaganda machine would be that biased to get that wrong.

Agreed... a Multitude of possibilities.

 

When Thailand is attempting to be ‘water tight’ the smallest of flaws will be highlighted.

While so many are panicking about 1 case of Covid-19 there are so many other bigger issues to deal with. 

 

All that is truly required to control Covid-19 is to keep the R number (infection spread rate) below 1 in any community.

 

The Covid-19 RT PCR test taken before departure covers the vast majority of cases. 

Careful monitoring of hospital admissions and those with symptoms takes care of the rest. 

 

The world could open back up, but it has tested itself into a panic.

I thinks thats too many what ifs Greg. I am guessing the answer will be the simplest one.

An article submitted in the Lancet on September 29 suggests that Covid-19 RT PCR tests (in the UK)  are suspected to have a false positive rate of between 0.8 and 4.0% 

 

https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30453-7/fulltext

 

 

 

Obviously those who present symptoms and also test positive fall well below the 0.8 to 4.0% false positive estimate outlined in the medical paper, however, when testing en masse i.e. 200,000 people daily the incidence of false positives could be significant. Significant enough to warrant policy change and further lockdowns when it's unnecessary.

 

Given the information on false positives - any positive test should really be carried out twice to confirm the result. 

 

 

Regarding the French lady, there are a number of possibilities: 

- She contracted Covid-19 from elsewhere, as nothing is water tight, even quarantine

- She has a regular cold and exhibits symptoms, the Covid-19 test was a false positive

Although I agree the 70+ figure doesn't match up should be 5.4%

The other age ranges as well. They are all off by two orders of magnitude.

 

Or maybe the missing cases that neither died nor are living are Schroedinger Patients. They are simultaneously dead and alive until their pulse is measured.

early on China supplied rapid test kits to various countries including the UK, they were soon deemed useless and inaccurate and were returned to China

Sure bet we did not get a refund for it - you'd think that China should be forced to pay for the entire world's test kits, protection wear and vaccine - but they won't , ther're the only nation making a mint from it

2 Days later sick, too soon!

Many people get sick within 2 to 3 days elsewhere in the world, 14 days would be unusually long, that's why 14 is used for the quarantine.

What makes you think anyone's panicking?

Please elaborate how that works in detail. Because I believe it’s a load of nonsense: PCR generally is highly reliable and one of the best testing technology that exists in modern diagnostic, and many Covid-19 PCR seem to have sensitivity and specificity rates of up to 99.9%. 

Keep dreaming.
