An American, who recently travelled to Phuket and Bangkok, tested positive for Covid-19 after returning to the United States. The man was tested prior to leaving Thailand and Thai health officials now say that result was a false negative. Thailand’s Department of Medical Sciences reviewed the man’s Covid-19 test that was taken right before leaving Thailand and now say the result is positive for the coronavirus.

A timeline of the man’s travel history was posted on the Bangkok Public Relations Department’s Facebook page. The man travelled through Thailand throughout February. He was released from the mandatory 14-day quarantine on January 26 and had tested negative for Covid-19 prior to being released. He left Thailand on March 4 and tested positive for Covid-19 on March 11 in the United States.

Here’s his travel timeline:

January 26 to February 16: He stayed in Bangkok’s Silom area.

February 17: He flew to Phuket on an AirAsia flight and checked in to Sri Panwa resort on Cape Panwa.

February 19: He returned to Bangkok on an AirAsia flight.

February 20 to 28: He stayed in Bangkok’s Silom. Reports say he didn’t go out much, mainly just to shop at a nearby convenience store.

March 1: He went to the hospital for a Covid-19 test, a requirement before travelling back to the United States.

March 2: The test result was inconclusive. He was tested a second time and the results came back negative for the coronavirus.

March 3: He boarded a flight back to the United States.

March 4: The Department of Medical Sciences reviewed the man’s second test results and found the man actually tested positive for Covid-19.

    Arrived from the US in Thailand January 12.
    Released from quarantine January 26.
    Tested false negative +/- March 4 in Thailand.
    Tested positive +/- March 11 in the United States.
    So he got infected in Thailand.
    No way that he got infected before January 12 in the US and still tests positive on March 11. That is 2 months, it is too much.

    I’ve said before – who can trust these tests here? Did he pay for each one? It’s not the first time this type of thing has been reported.
    Pretending everything is ok, then it’s not, when another country carries out a test.

    We all know that there is plenty of Covid in Thailand, it just doesn’t seem to be as dangerous to the Thais as to other groups. Might as well open the country.

    given that the PCR tests are notoriously fallible, he probably wasn’t and isn’t sick. I again and again post (https://off-guardian.org/2021/01/25/who-finally-admits-pcr-is-not-a-diagnostic-test/) the statement from the WHO which says the PCR test is NOT a diagnostic test. That it must not be relied on to say whether one has CV or not, as also had said Dr Kary Mullis, the inventor of the PCR test.

    But nobody thinks about the fact that THE test that every country uses is flawed and gives BS results.

    COVID testing in Thailand, like most things are not very reliable. That’s the reason the “numbers” have been so low over the last year…..well, besides the fact that testing is also limited.

    Geoff, I agree with your conclusion based on what’s reported here, but what’s reported here is NOT what’s reported in the source article (the Phuket Post).

    There is NO mention in the Phuket Post that he “tested positive for Covid-19 on March 11 in the United States.”

    According to the Phuket Post he had an inconclusive test on 1 March followed by a second test that was negative on 2 March; he then flew to the USA on 3 March and on 4 March the Thai Dept of Med Science reviewed the test and changed the result to positive; on 11 March the Thai Dept of Med Science posted the results on their Facebook page to try to track ‘n’ trace his contacts.

    Presumably between 4 and 11 March they had to not only inform the US but also to trace his movements in Thailand, particularly detail of his last 14 days here (as “he drove by himself back to his accommodation” in Bangkok he was apparently not a tourist, but reportedly after his 14 days in quarantine all he did for a month in Silom was he “sometimes went shopping at a nearby convenience store” ?).

    He may have had a follow up test in the US once he was told his test result here had been changed from negative to positive, but there’s NO report or suggestion of that in the Phuket Post.

    I agree with Bangkok Ben. I think there are thousands infected with Covid in Thailand. Either the Thais are more resistant through some other pathogen exposure such as Dengue or some other aspect of their DNA. I’m sure thousands are sick and laying around in villages and then overcome what is thought to be a case of flu. How can numbers continue to be around 65,85,110,80,73 day after day. It’s the only country in the world where this is happening. It comes down to the number of tests done each day test more and you will find more. Test a shit load and you will find a shit load.

    This is absolutely logical, these tests are not reliable at all and, depending on how many cycles they use, you can be negative or positive.
    These tests don’t detect covid, they only detect some genetic material in your body. So it’s only bullshits.
    There is no covid in Thailand, only some flu.

    David Mann,

    “It comes down to the number of tests done each day test more and you will find more. Test a shit load and you will find a shit load.”

    Unfortunately we aren’t allowed to widen the scope of our testing. A serological study to test SARS-CoV-2 antibody prevalence in the general population was given permission to be conducted by a reputed international diagnostics company in conjunction with a local university, but halfway through the permission was suddenly rescinded and they had their data confiscated and remaining test kits seized when it became clear what the outcome might indicate. It is needless to say more.

    Yes, dreqo, that’s what the Thaiger article says, which I quoted – but my point, which you’ve completely missed, is that it is NOT what the source article says.

    If the “source” (the Phuket News) is the ONLY source for the Thaiger article – and it’s the ONLY source for all reports of this story elsewhere – then the Thaiger’s report that he “tested positive for Covid-19 on March 11 in the United States” is WRONG.

    The source report does NOT say or even suggest he was ever tested in the US – it ONLY says that he was tested in Thailand.

    “It’s the only country in the world where this is happening. It comes down to the number of tests done each day test more and you will find more. Test a shit load and you will find a shit load”

    As Dreqo and John Brig have both pointed out already this is simply untrue – Thailand is NOT “the only country in the world where this is happening”.

    Other countries have similarly low mortality rates and low case fatality rates – Taiwan, for example, with a population of 24 million, has had only 10 (ten) deaths: a CFR of 1.02%. Singapore, with a population of 6 million, has had 29 deaths: a CFR of 0.048 %.

    The reason for Thailand’s low CFR is the same as Singapore’s – not because they “are more resistant through some other pathogen exposure such as Dengue or some other aspect of their DNA”, or because they have a miracle cure, but far simpler – and no mystery.

    In both Thailand and Singapore the vast majority of the cases have been migrant workers who were not only living and working away from the general population and quarantined quickly but who are predominantly young, fit and healthy so who are the least likely to die from Covid – if they weren’t young, fit and healthy they wouldn’t be here doing the jobs they are – and AFAIK literally not one migrant worker in Thailand in the Samut Sakhon outbreak died of Covid.

    The idea that if you “test more you will find more” only works if you are testing across all the demographics.

    It fails to work and simply becomes a massive waste of money if you are testing the wrong people.

    In the UK, for example, although the UK has carried out millions of tests very few have been targeted and tests have been mainly voluntary, so most of those who’ve been tested have been those who wanted to be tested – completely overlooking that those MOST likely to have Covid (the lower paid, socially disadvantaged, living and working in crowded and cramped conditions) are the LEAST likely to want to be tested even if symptomatic as they don’t want to miss work or be quarantined, so the number of cases is probably even higher than tests indicate – particularly as the UK’s track ‘n’ trace system is effectively next to useless.

    In Thailand, on the other hand (as in Taiwan and Singapore) testing is limited but targeted (as well as, effectively, obligatory) so that those MOST likely to have Covid are also MOST likely to be tested – IIRC in the high risk target, for example, as many as 44% tested positive, while that dropped to 22% in the medium risk target and 7 – 12% in the low risk target, and the track ‘n’ trace system is simple but works.

    Think of it as the difference between a sniper and the rest. According to the USMC, the US Army in Vietnam fired 200,000 rounds per kill, the USMC 50,000 rounds per kill, and USMC snipers 1.3 rounds per kill.

    Agreed 100%, Dreqo.

    There are no excess deaths (the number of deaths actually went DOWN slightly last year, reportedly probably due to mask wearing, increased hygiene / hand washing, restricted travel, etc) and there certainly aren’t “thousands … sick and laying around in villages” – this would be all over social media if true and even out in the sticks while people aren’t paranoid about Covid it’s taken very seriously.

    I think what’s obvious here, despite many a tantrums of denial, is that Thailand is one of verrry few that are giving an accurate portrayal of the real story. There certainly could be thousands of infected people in Thailand, undeniable transmission rates would say so. The fact of the matter is that the threat has clearly been blown out of proportion, to serve a number of agendas in the west. Thailand is a fantastic example of unintended truth telling. The west has turned it’s negative PR machine against Thailand in recent months, and likely for that very reason. I say good on ya, Thailand.

    For the PCR–polymerase chain reaction–test to be accurate the number of cycle threshold amplification of the DNA strand of the swabbed virus needs to be under 25 cycles. Most tests put out false positives because the cycles are many cycles over that number. Most PCR tests in the US are as high as 45 and not under 36. Each cycle is a quantum leap in magnification of the test sample swabbed from the patient. When 35 or more cycles are deployed the result of the test is meaningless.

    However, many, many labs use 40 or even 45 cycles.

    At more than 35 cycles, the test yields an overwhelming percentage of false-positives. Plus, the PCR test was never made to detect the amount of viral load and that is what determines whether a person has Covid or not. One can’t say if it was the Thai test at fault, the possibility that the man was exposed to Covid while traveling, or that the US test is faulty. To judge any of these possibilities as being conclusive lacks information.

    Issan John. You frequently accuse people of not reading your posts and jumping to conclusions. I didn’t claim there would be lots of dead people. I believe the number of positive cases in Thailand is somewhere around the 250,000 level and probably around 400-500 dead. Not the high levels seen in the west primarily due to less obesity and a younger population in Thailand. Other factors such as isolation of migrants is also a factor. As you rightly say, fit and healthy people don’t generally die of Covid. But it’s not 25,000 infected and 80 dead. It simply can not be. Not in the way the outbreaks have occurred. Had they occurred in a single location, then possibly. But there have been outbreaks in a number of provinces with no obvious connection. I’m not suggesting there are millions and thousands dead. Many factors, including swift lockdown have been a success in managing the Covid numbers. I’m simply saying the official figures are misleading

    You do not have to die for the virus to devastate your body–your own immune system attacks you. Of course, stroke, heart and lung damage, nerve and brain damage are not reported since these patients are seldom tested. Thais passively suffer and die at home–few autopsies are performed here in murder cases. If you are okay operating at 30-50% of normal forever then do nothing. TIT.

    Well, last year I got tested at a famous hospital here.. Standard operating procedures: 2 PCR tests. If the first one comes back negative then your considered negative. If the first one comes back positive, 2nd test is sent to a reference lab for validation. If the reference lab confirms positive, then your positive. If the reference lab comes back negative, it is seems the definitive test snd your declared negative.

    My issue was the first test came back positive. They started me on a wicked (and useless) cocktail of drugs. A few days later I was told by the hospital my 2nd test was positive and must be admitted to the hospital immediately. That same day I was in isolation,etc….a few days later I insisted for another test which came back negative snd I was released.

    The problem was….that I found out 6 weeks later that my 2nd test was NOT positive, it was negative and the hospital did not tell me. The same day they said I must be admitted was the name day they got the reference labs results of negative. They even changed my hospital records to reflect the false info.

    I have to be on deaths door to trust any doctor or hospital here anymore.

    All a little odd, Dave.

    How do you know they changed your hospital records and that the second test was negative?

    It’s not impossible, obviously, but I can’t help wondering why you’re commenting on it here, without naming the hospital, rather than you or your insurers demanding a refund from the hospital having reported it?

    No insurance company would accept that, if it happened and was documented, and just do nothing.
