 15 million new cases each year
High Risk Behaviors
 Being sexually active with more than one person
 Engaging in unprotected sex
 Selecting high risk partners
 Using alcohol and other drugs

 Virus that can cause genital warts or asymptomatic

 Most common STD in the US


50 – 75 percent of sexually active individuals acquire HPV
during their lifetime
6 million new cases a year
 Symptoms and potential health problems:
 Genital warts – Pink or reddish warts with cauliflower like

 Throat warts
 Cervical cancer
 No treatment
Chlamydia

organs of both males and females
 Symptoms:



No visible symptoms in over half of all infected
Discharge and burning sensation while urinating
Irreversible damage such as infertility
 3 million new cases a year
 Can be treated with antibiotics, but no immunity
develops so a person can become infected again
Genital Herpes
 An STD caused by the herpes simplex virus
 Causes cold sores or genital sores
 Can pass on disease when no visible sores are present
 Prevalence:
 About 1 in 6 people have herpes

Sore will heal on its own
Disease can spread to other parts of the body

Damage internal organs, cause paralysis
 Treatment:
 Easy to treat in early stages
 If not treated within the first year complications can occur
HIV and AIDS
 Human Immunodeficiency Virus – a virus
that attacks the immune system

Infection is progressive, not instant
 Acquired Immune Deficiency Syndrome – a
disease in which the immune system of the patient
is weakened
 Transmitted through blood, semen, vaginal
secretions and breast milk
Consequences of STDs
 Long term and serious
 Incurable
 Cause cancer
 Embarrassing
 Affect ability to reproduce
 Can be passed to children
