The rate of STIs in high-end escorts are actually LOWER then the general population, that may translate to high end brothels, as they do regular screening and checks for their own sake. You don't think they wonder where your dick has been? The rate of transmission from men to women is more prevalent then the other way around. They take their health very seriously, and judging from alot of comments, they know alot more about STIs then the average punter.
