On the subject of immunizations, I wanted to add to the pilots out there, and to all folks who travel internationally, that it's probably advisable to be vaccinated, or current on your Hepatitis A vaccine.
A lot of countries, even "developed" countries, may not have the same sanitation standards that we have. Actually, to be honest, I know a bunch of folks who contracted Hepatitis A in Baltimore when they were students at Johns Hopkins Medical School. They think they got it from a Thanksgiving turkey that they all cooked and shared together. Food can be bad anywhere. I have a friend who is a well-known musician, who was out on a world tour with his band, and got Hep A in South Korea. He was staying in the nicest hotels, eating in the nicest restaurants, and watching what he ate, but he still got it, and he got fairly sick, so I would think that you pilot folks would want to be protected.
I dunno, maybe the airlines already mandate that international pilots get the Hep A vaccine. Kev? Doug? TyphoonPilot? Calcapt? Perhaps I should take these comments to Dr. Forred and ask him as well!
I know VERY little about infectious disease medicine!
