Hi. I'm an American. I flew to Mexico not long ago and going to fly back to the US soon. The thing was when I first got to Mexico, I didn't feel good. After a week or so, I went and got a covid test and was tested positive. As of right now, I am still coughing. I also will be planning to leave soon as well as my trip here wasn't going to be that long.



My question is... if I get tested positive for covid the day before I fly, how soon can I take another covid test? I heard if you get tested positive, you need to quarantine for 5 days? I do have a place that I could stay at so I won't need to book a hotel in case this happens. I had heard someone mentioned they went and got another covid test at few other locations on the same day or next day and one of the test showed as negative. So its possible its a false positive? So is it possible if you get a positive covid test... then you go to another location the same day and if that test show as negative... then you are good to leave tomorrow? I am asking this because I have to leave by a certain date because I only got a certain amount of days here such that I would not want to overstay. But are there lot of cases where people overstay due to this? Every since the US changed the covid test from three days to one day, it seems like a huge issue when traveling.



The other issue I have is this. I normally book a flight with delta or jetblue or american a week or more before my flight and always book the economy ticket because it is the cheapest. I will most likely book either delta or jetblue. I know jetblue I can't now because I have a carry on so you have to pay more no matter what. So if I book Jetblue Blue... I could cancel my flight and get ecredit or rebook right? I cannot book Jetblue Basic since I do have a carry on. Do I need to buy insurance? The thing is I never paid for insurance whenever booking a flight. But would this be recommended? I could imagine how much people have a flight to go back to the US soon and the day before you take the covid test, you get tested positive. Now if you bought an economy ticket, then you lose the full value of it now right? I know back then airlines were much more lenient. Also when I book tickets, I always book a one way each time and never roundtrip.



Does anyone have advice on this for me? Normally I wouldn't really think about these issues but because I got tested positive for covid about a week ago after I arrived, this has me concerned when I leave. Thus concern is when I get tested the day before I leave.



Now if I get tested positive for covid the day before I leave, could I take a test say two or three days later and if negative, then I could leave the next day? I also heard about the you could get a note from a doctor to excuse you from it. Can someone explain to me how that works? So if you get tested positive the day before you leave, how soon can you see a doctor where they declare you okay to fly? But you still need to wait at least 5 days to see that doctor? Could you actually see a doctor that day you tested positive for covid? I still have the copy of the positive covid test from earlier this month when I went and got the test. I assume the doctor note thing relates to if someone keeps getting tested positive every 5 days or so for multiple times and then the doctor if they see if you have no issues, give you a note that you are okay to fly? Thanks.
