Hi @angiev18, I am happy to hear that your surgery was finally approved and that you are preparing for the trip. I have added a link below to one of the discussions on Connect about tips for traveling safely during Covid-19. I think it would benefit you greatly to read some of the members solutions and possibly pose your own questions.
