Health: SOME SEXUAL TRANSMITTED DISEASES (STD/STI)

SHARE
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.
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.
The causes of STDs are bacteria, parasites and viruses. There are more than 20 types of STDs, including

Chlamydia
Gonorrhea
Bacterial Vaginosis
Genital herpes
HIV/AIDS
HPV
Trichomoniasis
Syphilis

Most STDs affect both men and women, but in many cases the health problems they cause can be more severe for women. If a pregnant woman has an STD, it can cause serious health problems for the baby.
