What are the ststistics with STD rates and prgnancies in Las Vegas compared to places with less prostitution?

I’m doing a report about prostitution in America and I’m having such a hard time finding the answer to Std rates and pregnancies in Las Vegas. If you could, please give me a website where you found your information. Thanks.
I need actuall statistics, as in actuall numbers and I need a source to say where I got the information.
