I am never offended when asked questions by my doctor. Shows she is doing her job correctly. And screening for sexually transmitted diseases is actually not just for these diseases. It can help with other diagnosis. Not to mention that they can be transmitted a lot more easily then people think.
Testing for a disease in someone who doesn't have symptoms is called screening. Most of the time, STI screening is not a routine part of health care, but there are exceptions:
The one STI screening test suggested for everyone ages 15 to 65 is a blood or saliva test for human immunodeficiency virus (HIV), the virus that causes AIDS. Younger teens at high risk should also be screened.
Everyone born between 1945 and 1965. There's a high incidence of hepatitis C in people born between 1945 and 1965. Since the disease often causes no symptoms until it's advanced, experts recommend that everyone in that age be tested.
Sexually transmitted diseases (STDs), or sexually transmitted infections (STIs), are generally acquired by sexual contact. The organisms that cause sexually transmitted diseases may pass from person to person in blood, semen, or vaginal and other bodily fluids.
Some such infections can also be transmitted nonsexually, such as from mother to infant during pregnancy or childbirth, or through blood transfusions or shared needles.
It's possible to contract sexually transmitted diseases from people who seem perfectly healthy — people who, in fact, aren't even aware of being infected. Many STDs cause no symptoms in some people, which is one of the reasons experts prefer the term "sexually transmitted infections" to "sexually transmitted diseases."
Sexually transmitted infections can be caused by:
Bacteria (gonorrhea, syphilis, chlamydia)
Parasites (trichomoniasis)
Viruses (human papillomavirus, genital herpes, HIV)
Sexual activity plays a role in spreading many other infectious agents, although it's possible to be infected without sexual contact. Examples include the hepatitis A, B and C viruses, shigella, and Giardia intestinalis.
Since the largest increase is in older men using VIAGRA it is clearly a behaviour problem - and one that they need to control. I am quite sure (and the latest stats bear this out) many of the "hot young things" they like to brag about are the kind you pay for and are neither hot nor young.
