That must have been decades ago.
Now the procedure is that you go to a pharmacy, get a couple of the test kits and the cure. Costs about eight bucks.
You test yourself before and after you return to the states. If you show positive you take the pills. Used to be three now is just one I believe. Over and done.
The vaccine and the preventative have some really bad side effects so instead you just tested and treated.
