Back before I knew the dangers of Hep, I would only test my boys for HIV. (Keep in mind that I fly males in from USA and parts of South America to work in Asia, expenses paid, so it's not cheap) So I had some Brazilians show up and within two weeks one of them got deathly ill. Spent a while in the hospital and it turned out he was in an advanced stage of Hep B. They flew him out in an emergency to be treated in his home country.
Then the drama started.
ALL the models he had worked with were then exposed to Hep B. I had a meeting with a doc who said that if you catch Hep B early enough, the vaccination would work against it if they exposed person got the vac. So we had to track down all these girls this guy had worked with over the two weeks, around 20 of them, and explain what happened and why they needed to go to the hospital and get shots, blah, blah, blah. It was a mess. The girls were livid and rightfully so. I paid for all of it, as I felt it was my responsibility to do so, but still, it was a mess. Then word started getting around that I got some girls sick and for a while it made it tough to get new girls. It's all good now but it was nasty for a while.
Now, all boys are tested for EVERYTHING before their plane ticket is even paid for. Then tested again once they arrive and start work. They hate it but that's the deal. The girls get tested for everything as well. I'd rather not go through all of that shit again, having people get sick on my watch. No thanks.
If they want to catch something, they can do so on their own time after I'm done with them, but not on my set.
Honestly, everyone needs to test for Hep B & C. These are quiet killers. Hep B has a vaccination, Hep C does not.
