Sexually transmitted infections (STIs) are passed from one person to another through oral, anal, or vaginal sex. Common STIs include chlamydia, gonorrhea, herpes, HIV/AIDS, and HPV. STIs are caused by bacteria, viruses, or parasites. While some STIs have symptoms, many do not, so testing is important. STIs can be prevented through abstinence or condom use and treated with antibiotics or antiviral medication to cure or manage the infection. Untreated STIs can lead to long term health issues.
2. What are Sexually Transmitted
Infections (STIs)?
STI is a term applied to a variety of infections
that are passed from one person to another
primarily through vaginal, oral or anal sex.
3. Common Types of STIs:
Chlamydia
HIV and AIDS
Gonorrhea
Pubic Lice
Genital Herpes (HSV-2)
Syphilis
Genital Warts (HPV)
Trichomoniasis
Hepatitis B
4. Modes of Transmission:
STIs are spread through contact:
Penis
Vagina
Rectum
Breaks in skin
Mucous membranes
And
Needle Sharing
Blood contact
Vertical transmission (Mother-to-child)
6. Prevention is the key:
Abstinence, or not having oral, vaginal or anal
sex, is the best way to protect yourself.
It is possible to get an STD even without having
intercourse through skin-to-skin contact.
Use latex condoms correctly for any type of sex
(vaginal, oral or anal) from start to finish.
7. How do I know if I have an STI?
Most people who have an STI have no
symptoms. A test from your health care provider
or local health clinic may be the only way to tell
for sure if you're infected.
If you do become infected, symptoms may
appear right away. Or, they may not show up for
weeks or months or even years. They may come
and go. Even if the signs and symptoms go away,
you can still infect other people if you have sex
with them. Or, they can still infect you!
8. Common Symptoms:
Pain or burning while urinating
Itching
Discharge
Unusual smell from the penis or vagina
For women, sharp pain in the lower belly
Growths
Bumps or sores
Rashes around the genitals or anal area
Many people can have no symptoms
(asymptomatic) and still pass on a STI.
9. Bacterial Infections:
Infections caused by bacteria, this agent
represents about half of the STIs identified.
Bacterial infections are curable. Medication does
not protect against future exposure.
10. Chlamydia and Gonorrhea:
Transmission
Direct mucous membrane contact with the germ
during sexual contact. Using condoms and dental
dams lowers chance of transmission.

Chlamydia, treatment for both infections are usually
given together .

will cure a person.
Other treatments are also available.

treated and managed with medication to reduce
symptoms and outbreaks caused by the virus.

positive after 6 months. Chronic Hepatitis may stay
with a person for a lifetime. About 10% of adults who
