Sexually transmitted diseases (STDs)
These are infections that are passed from one person to another through sexual intercourse.
The causes of STDs are bacteria, parasites, yeast, and viruses.
STDs include but not limited to:
Chlamydia
Genital herpes
Gonorrhea
HIV/AIDS
HPV
Syphilis
Trichomoniasis
Most of the STDs affect both men and women, but in most cases the health problems they cause are more severe for women.
If a pregnant woman has an STD, that can post a serious health problems for the baby.
PREVENTION:
Have "safe sex": for each sexual act, use a new latex condom, whether it be oral, vaginal, or anal sex.
Abstain: abstaining from any sexual act is probably the most effective way to avoid becoming infected with an STD.
Vaccinations : there are vaccinations that can protect from eventually developing some types of cancer caused by two STIs - the HPV (human papillomavirus) and Hepatitis B vaccines.
Drink alcohol in moderation: people who are drunk are more likely to engage in risky behavior. Avoid using some recreational drugs, which may also affect judgment.
Explain you want safe sex: before engaging in any sexual act with a new partner, make it clear that you would only consider safe sex.
Check for infections: before sexual intercourse with a new partner, check that the partner and yourself have no STIs.
Be faithful to one uninfected partner: be in a long-term relationship with a person who is not infected, and remain faithful.
The most reliable way to avoid infection is to avoid having anal, vaginal, or oral sex
Education: parents, schools, and society in general need to teach children about the importance of safe sex, and explain how to prevent becoming infected with an STI.
