Millions of new infections occur every year in the United States. STDs are passed from one person to another through sexual activity including vaginal, oral, and anal sex. They can also be passed from one person to another through intimate physical contact, such as heavy petting, though this is not very common. That is why it is important to get tested if you are having sex. If you are diagnosed with an STD, know that all can be treated with medicine and some can be cured entirely.
If you have sex — oral, anal or vaginal intercourse and genital touching — you can get an STD , also called a sexually transmitted infection STI. Thinking or hoping your partner doesn't have an STI is no protection — you need to know for sure. Condoms, when properly used, are highly effective for reducing transmission of some STDs. But no method is foolproof, and STI symptoms aren't always obvious. Also, inform your partner or partners so that they can be evaluated and treated.
When you get an STI you may not have any obvious symptoms. You can feel perfectly okay and not realise you have an infection. If you notice any of the above symptoms, or if you had sex without a condom or a dental dam, you and your sex partner s should see a doctor for an STI check. The earlier you are diagnosed with an STI, the easier it is to treat which also reduces the chances of you developing further health complications.
Sexually transmitted diseases STDs — or sexually transmitted infections STIs — are generally acquired by sexual contact. The organisms bacteria, viruses or parasites that cause sexually transmitted diseases may pass from person to person in blood, semen, or vaginal and other bodily fluids. Sometimes these infections can be transmitted nonsexually, such as from mother to infant during pregnancy or childbirth, or through blood transfusions or shared needles. STDs don't always cause symptoms.
