[Brian Jacobs]

Brian Jacobs  asked the Naked Scientists:
   Dear Chris,
 
It is common cause that there are a number of diseases which can be transmitted from one individual to another because of unprotected sex.
 
My question is whether the diseases that can and are transmitted are restricted to those that are mostly publicised or could the flu be transmitted from one person to the other through unprotected sex?
 
Thanks,
 
Brian. H. Jacobs
