Transcript of STD´S

It can grow rapidly and multiply easily in warm and moist areas of the reproductive tract.
Genital herpes is a contagious infection caused by the herpes simplex virus (HSV). There are two different strains, or types, of HSV: herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2).

HIV destroys the body's immune system by killing the blood cells that fight infection. Once HIV destroys a substantial proportion of these cells, the body's ability to fight off and recover from infections is compromised
Bacterial Vaginosis
Bacterial vaginosis is a mild infection of the vagina caused by bacteria.

Genital Herpes
Human Papillomavirus (HPV)

More than 40 HPV types exist, and all of them can infect both men and women. It can infect other regions of the body, including the mouth and throat; and cause cancers of the cervix, vulva, penis, and mouth.

Syphilis infections, caused by a bacterium that has tail and can move called:
Treponema Pallidum. This is
passed from person to person during vaginal, anal, or oral sex through direct contact with sores, called chancres.

Chlamydia can be transmitted during vaginal, oral, or anal sexual contact with an infected partner.


Its caused by the single-celled protozoan parasite called:
Trichomonas vaginalis
and it is common in young, sexually active women.
The parasite also infects men, though less frequently.
The parasite can be transmitted between men and women.
Whenever physical contact occurs between the genital areas.

Viral Hepatitis
Viral hepatitis is a serious liver disease that can be caused by several different viruses, which can be transmitted through sexual contact. There are more than 3 types of HAV’s such as Hepatitis A virus, Hepatitis B virus, and Hepatitis C virus.

Sexually transmitted diseases
STD’s are transmitted via the following bodily fluids:
blood, semen, pre-ejaculatory fluids, breast-milk, and vaginal secretions.

saliva can spread herpes simplex 1 and 2
. Skin to skin contact can also spread STD’s. Unprotected oral, anal, and vaginal sex all pose risk of contracting an STD.
Some diseases are caused by
These are
syphilis, Chlamydia, gonorrhea, vaginitis, and NGU (nongonococcal urethritis)
. Other diseases are caused by a

herpes and AIDS
The Human Immunodeficiency Virus (HIV) causes

Human Papilloma Virus
causes Condyloma, or Genital Warts.
Microscopic organisms
are the cause of scabies, crabs and trichomoniasis.

Sores (either painful or painless)
Blood in urine
Burning sensation when urinating
Unusual discharge

At first there may be no symptoms....
if untreated....
Answer the following questions:
1. Chlamydia is caused by:
2. If this disease is untreated, It can lead to:
3. If you are sexually active can you contract chlamydia?
4. Why is chlamydia considered a silent disease?
5. In what period of time can symptoms appear?
6. What are the most common symptoms?
7. Where can chlamydia manifest itself?
8. What is the treatment?
9. Is chlamydia easy to cure?
10. List the complications that chlamydia can cause if it is left untreated:

Unlike Chlamydia
, gonorrhea symptoms are more obvious in men than in women.
Men have pain on urination and milky urethral discharge three or five days after contact.
In women, there are usually no symptoms.
until it spreads to the ovaries.

It causes blindness in newborns.
1. What is gonorrhea?
2. Gonorrhea is caused by:
3. Gonorrhea can appear in:
4. Why is gonorrhea easy to transmit?
5. Most of the people infected with gonorrhea show mild or no symptoms, is this true?
6. In what period of time can symptoms appear?
7. List the most common symptoms for men and women?
8. What are the complications if gonorrhea is left untreated?

Can gonorrhea be cured?
Yes, gonorrhea can be cured with the right treatment. Medication for gonorrhea should not be shared with anyone. Although medication will stop the infection, it will not undo any permanent damage caused by the disease.
Painful urination usually indicates gonorrhea
3. Tertiary stage: Lasts until patient dies. It weakens the arteries and damages the brain.
Syphilis has three stages:
1. Primary stage: an ulcerated sore. The ulcer heals itself, but it just gearing up to for the next stage.
2. Secondary Stage: The bacteria spread throughout the body abd a rash forms all over, although is not itchy.
The parasite is passed from an infected person to an uninfected person during sex.
In women, the most commonly infected part of the body is the lower genital tract (vulva, vagina, or urethra)
, and in men, the most commonly infected body part is the inside of the penis (urethra).
What are the signs and symptoms?

About 70% of infected people do not have any signs or symptoms. When trichomoniasis does cause symptoms, they can range from mild irritation to severe inflammation. Some people with symptoms get them within
5 to 28 days
after being infected, but others do not develop symptoms until much later.

Men with trichomoniasis
may feel itching or irritation inside the penis, burning after urination or ejaculation, or some discharge from the penis.

Women with trichomoniasis
may notice itching, burning, redness or soreness of the genitals, discomfort with urination, or a thin discharge with an unusual smell that can be clear, white, yellowish, or greenish.

Trichomoniasis usually can be cured with these antibiotics:
Metronidazole, or
These drugs usually are given by mouth in a single dose. But the topical medicines don't work as well and may not cure you. They might, however, ease the symptoms.
There are several types of hepatitis. There is no treatment and no cure, but there is a vaccine.
The word hepatitis is a catch-all term that refers to any inflammation of the liver -- the irritation or swelling of liver cells from any cause.
HEPATITIS can be caused by a group of viruses known as the hepatitis viruses, including A, B, C, D, and E.
The five hepatitis viruses can be transmitted in different ways, but they all have one thing in common:
They infect the liver and cause it to become inflamed.
Hepatitis B and C may progress to chronic hepatitis, in which the liver remains inflamed for more than six months. This can lead to cirrhosis, liver cancer, and sometimes death.
Hepatitis A
is usually spread by eating food or drinking water contaminated with feces carrying the virus. Hepatitis A is the least dangerous.
Hepatitis B
can spread through sex (it is 100 times easier to spread through sex than HIV), blood transfusions, and needle sharing by intravenous drug users. The virus can pass from mother to child at birth or soon afterward.
Hepatitis C
is usually spread through contact with blood or contaminated needles, including tattoo needles. As opposed to hepatitis B, hepatitis C is only infrequently spread through sex.
Herpes is a common sexually transmitted disease (STD) that any sexually active person can get. Most people with the virus don’t have symptoms.
It is important to know that even without signs of the disease, it can still spread to sexual partners.
Genital Warts (HPV)
It's not necessary to have sexual intercourse to get a sexually-transmitted disease (STD). The human papillomavirus (HPV) that causes genital warts can be transmitted by close skin-to-skin contact. Some types of HPVs cause cervical or anal cancer, and vaccines are available to protect against the most dangerous types.
Other HPV types cause genital warts, which can be raised, flat, or cauliflower-shaped. HPV infection can occur in people who have no symptoms or visible warts

How can you get bacterial vaginosis?

Certain things make it more likely to happen. Your risk of getting bacterial vaginosis is higher if you:
Signs or symptoms...
Normally, there are a lot of "good" bacteria and some "bad" bacteria in the vagina.
The good types help control the growth of the bad types.
In women with bacterial vaginosis, the balance is upset. There are not enough good bacteria and too many bad bacteria.
Have more than one sex partner or have a new sex partner.
The most common symptom is a smelly vaginal discharge. It may look grayish white or yellow.
Doctors diagnose bacterial vaginosis by asking about the symptoms, doing a pelvic exam, and taking a sample of the vaginal discharge.
Bacterial vaginosis usually does not cause other health problems. But in some cases it can lead to serious problems.
What are these problems?
If you have it when you are pregnant, it increases the risk of miscarriage.
If you have it when you have a pelvic procedure you are more likely to get a pelvic infection.
If you have it and you are exposed to a STI (including HIV), you are more likely to catch the infection.
non gonococcal urethritis
Nongonococcal urethritis (NGU)
is sometimes called nonspecific urethritis (NSU).
It is an infection of the urethra.

The symptoms of NGU are similar to gonorrhea.
NGU is caused by a bacterium called
Chlamydia trachomatis.
It usually takes one to three weeks after the infection occurs before a man develops any symptoms of NGU.
The first symptom is usually a leakage of milky fluid (discharge) from the tip of the penis.
There also may be mild burning of the penis during urination.
Sometimes there are no symptoms.
If left untreated, the infection may move up around the testicles, causing pain, swelling and sterility.
how is NGU treated?
NGU is most often treated with medicines known as antibiotics. Antibiotics kill the germs causing the infection.
The symptoms of NGU involve a slight burning during urination that is sometimes accompanied by a slight (usually clear) discharge (drip) from the urethra.
in female ...
Mucous membranes and STD transmission.
STD’s and STI’s are transmitted through mucous membranes which are located in the vaginal cavity, urethra in males and females, anus, and mouth.

Other routes of infection:

Needle sharing and handling bodily fluids without gloves also poses great risk.


a. Infertility (inability to become pregnant) Gonorrhea and chlamydia cause these infertility issues.
b. Cervical cancer in women and oral cancers in men.
c. Prenatal infections from infected mothers
d. Blindness, organ failure
e. Death
