Theres be a fair bit of talk about Stuart maybe picking something unwanted up, while in the company of Michelle. But I just wondered if Edemol does any screening for STDs before they go in.

I guessing not, as legally it would be a ticky one, as refusing someone entry (forgive the pun ) because of an incurable infection would be classed as descrimination (might be different for competitions though, being different to employment law). Alternatively, letting a HM in the house but announcing the HM had one would be classed as an invasion of privacy, and even demanding a test could maybe be classed as an invasion of their privacy (kinda ironic ) and human rights?

But then again, if non of the above legal hurdles are so high, doing so might be seen as a positive safe sex message, and not doing so classed as irresponsible, so we might see announced testing in the next BB?

It's a reality show.
When a person goes out this Friday a lot will have sex on the basis of "well they didn't look ill" - so it is in the house. Now one forces HMs to have sex and those that do take the same risks that everyone else does in real life.

You either take those risks or don't have sex.
These are adults with free-will.
