I am reading worrying news. I hope it is fake news, but it has me worried because I do see Thais capable of it. The news is that some private hospitals fake that you have a positive corona test so they can earn on you because then you need to do 10 days quarentine there at 10.000 baht a day.

I have the following questions:
1) Say in the Test&Go plan on Day 1 I get a positive test. Can I then get a second opinion at another hospiral and the negative test wins?
2) If the result is positive, do I - under Test&Go - then really have to quarentaine at a hospital which is very expensive? Can I not just stay at the hotel?
3) How long is the quarentine? A few days and then I am still free to start my holiday?
4) Does in general the travel insurance also pay out when you have to quarentine because of a positive test or only when you really have symptons and need treatment for that?
