Your statement "Like in any other country." caught my eye and made it quite sore. Here is the graph from Our World in Data. Comparison between UK and Thailand and if you have a good look you'll see that since July 10th Thailand is not reporting the number of tests. Did I miss the topic again?
Official number 35000 a day, as cases just starting to pop up in the other provinces. Real number will be 3 times higher due to lack of testing, asymptomatic and mild cases.
