    National and local testing is showing that the number of new infections is stable. But, it’s possible that there is a pocket or two that could cause future problems.

    More so it shows that the amount of testing is stable.

    If 5% of the number of people tested in Bangkok are positive its one thing.  If at the same time 5% of those tested in Con Buri are positive, that's two things, Chaing Mai three things etc etc.  Then you bolt on an R rate above 1 and you potentially have serious problems.

    A randomized survey of 2400 tests in one day is sufficient to determine positivity rate, if conducted in a limited area, like Chonburi.

     

    But, I'll bite: what level of testing in Chonburi do you think is sufficient?

    Further to my previous reply this chart shows the number of lateral flow tests being carried out daily in England (56 million population)

    I don't profess to be an epidemiologist, so I can't provide a robust scientific answer for you.

    But anecdotally I can say that in the UK when they have cases of new variants pop up - most recently for the South African or Brazilian variants - the aim is to surge test an area by encouraging everyone within the area to take a test within 2 weeks.

    So if Pattaya has a population of 105,000 I guess 7,500 tests per day for 2 weeks would do it.

    If Thailand could be bothered to at least try it once it would provide more robust data for everyone, and if it were proven that cases are very low I would be delighted.

    My concern is that if nothing else, this phase shows that the virus can and does spread within Thailand and that Thai people can catch it.  Something that has always appeared to be discounted previously.

    May 2: new infections in Chonburi down to 89.

     

    It looks like about 2400 lab tests for random people yesterday, probably a positivity rate below 5%.

    I shouldn't raise your hopes too high on the back of those figures.

    A continued pathetically low amount of testing will be skewed by people with no symptoms keen to prove they don't have it, rather than those with symptoms keen to get shipped off somewhere for 14 days.

    Thailand should at least choose one place to carry out comprehensive surge testing on a large scale, if only to allay concerns and prove, as you hope, that the infection rate is lowish.

    But we know that that will not happen.....at least not yet.

    Thailand conducts about 50,000 tests a day. The number of individuals tested is somewhat less than 20,000, per your chart.

     

    The question on the table was how many tests were conducted, not how many individuals were tested.

    Do you have a source for that please?

    I look at: https://ddc.moph.go.th/viralpneumonia/eng/situation.php  and total number of laboratory tests completed.

    If you took 27th April and deduct figures from 26th April the difference is 18,054.

    I had assumed that this was the number of tests?

    In terms of the rate of new cases per day increasing - the recent rapid growth in India has seen the increase in new daily cases move from around 22 per million to 204 per million in 34 days.

    Thailand has a rate around 22 per million now, so it is quite easy to believe there could be 15000 new cases per day in Thailand a month from now. 

    Just to add a further note to my own post - the UK topped out at around 881 new cases per million per day around 10th January.  If it reached that kind of level in Thailand you would be looking at around 62,000 new cases per day!

    Actually Thailand's official policy is to test symptomatic cases and have on numerous occasions said that mass testing costs too much money so they don't actively seek asymptomatic carriers as you suggest.If you check testing stats you will see that Thailand has rather low testing rates.Here are the current testing rates per million of population, US 1646,UK 1842 and Thailand 385.

    I'm not sure how to interpret the figures you quote.

    According to Worldometer today - since the start of the pandemic the testing rates per million are now  UK 1,512,475 (yes that's one and a half million per million) and Thailand is 22,896.

    UK has capacity to do more than 800,000 tests per day currently.
