Where a Mask all the time
Obviously in the west, wearing a mask has become something of a political talking point about personal freedom. In Myanmar it’s not a must to wear a mask. You can be fined for not wearing a mask although I doubt they are doing much enforcement of this. You also cannot enter most buildings without a mask. So be prepared to wear a mask, get your temperature checked, and give your name and phone number (in case they need to contact you about a case).
