Diseases
The Consequences
Of
Unprotected Sex

Bacterial
Chancroid (Haemophilus ducreyi)
- a bacterial infection that causes open sores on or around the genitals of men and women.
Signs & Symptoms

Has sharply defined, undermined borders
Has irregular or ragged borders
Has a base that is covered with a gray or yellowish-gray material

Chlamydia (Chlamydia trachomatis)
Signs & Symptoms
Painful urination
Lower abdominal pain
Vaginal discharge in women
Gonorrhea (Neisseria gonorrhoeae)
Signs & Symptoms
Greenish yellow or whitish discharge from the vagina/penis
Conjunctivitis (red, itchy eyes)
Burning in the throat (due to oral sex)

Granuloma inguinale
Signs & Symptoms
Small, painless nodules appear after about 10–40 days of the contact with the bacteria.
nodules burst, creating open, fleshy, oozing lesions.
Syphilis (Treponema pallidum)
Signs & Symptoms
Primary

syphilis is typically acquired by direct sexual contact with the infectious lesions of another person.
Secondary
syphilis occurs approximately four to ten weeks after the primary infection.
Latent
syphilis is defined as having serologic proof of infection without symptoms of disease.
Tertiary
syphilis may occur approximately 3 to 15 years after the initial infection, and may be divided into three different forms: gummatous syphilis (15%), late neurosyphilis (6.5%), and cardiovascular syphilis (10%).

Fungal
Candidiasis (yeast infection)
Signs & Symptoms
Redness
Itching Discomfort
Viral
Viral Hepatitis
is liver inflammation due to a viral infection. It may present in acute (recent infection, relatively rapid onset) or chronic forms.
Hepatitis B
Identified methods of transmission include blood (blood transfusion, now rare), tattoos (both amateur and professionally done), sexually (through sexual intercourse or through contact with blood or bodily fluids), or via mother to child by breast feeding (minimal evidence of transplacental crossing).
Herpes Simplex
Signs & Symptoms
Blisters or Ulcers
most often on the mouth, lips and gums, or genitals
Enlarged Lymph Nodes
in the neck or groin

HIV (Human Immunodeficiency Virus)
Signs & Symptoms
The majority of people infected by HIV develop a flu-like illness within a month or two after the virus enters the body.
HPV (Human Papillomavirus)
Molluscum contagiosum
- is a viral infection of the skin or occasionally of the mucous membranes, sometimes called water warts.
The virus may not cause symptoms for weeks to months after it has entered your body. You may see small, raised bumps on your skin. The bumps are firm and smooth.
Parasites
Crab Louse
also known as the pubic louse, is an insect that is an obligate ectoparasite of humans. It is typically found in pubic hair, but may also live on other areas with coarse hair, including the eyelashes. They cannot jump, and feed exclusively on blood. Humans are the only known hosts of this parasite
Scabies
also known colloquially as the seven-year itch, is a contagious skin infection caused by the mite Sarcoptes scabiei. The mite is a tiny and usually not directly visible parasite which burrows under the host's skin, causing intense allergic itching. The infection in animals other than humans is caused by a different but related mite species, and is called sarcoptic mange.
Protozoal
Trichomoniasis
sometimes referred to as "trich", is a common cause of vaginitis. It is a sexually transmitted disease, and is caused by the single-celled protozoan parasite Trichomonas vaginalis producing mechanical stress on host cells and then ingesting cell fragments after cell death.
Preventions
Contraceptives such as condoms provide a barrier against the contraction of STDs from an infected individual. Condoms, however, need to be used correctly to prevent transmission. Used condoms must be removed and disposed of appropriately to prevent spread.
Barrier Contraceptives
Sexual Health Checks
Attending a sexual health screen before engaging in sexual contact with a partner helps to prevent new cases of infection. Checking is also needed before resuming sexual relations if a partner has engaged in contact with someone else.
Examples of important vaccines now available are those offering protection against hepatitis B and some strains of human papilloma virus (HPV)
Vaccination
Abstinence
One of the best ways to prevent transmission of STDs is to avoid sexual contact with other individuals.
Causes ::
caused by the fastidious Gram-negative streptobacillus Haemophilus ducreyi.
Treatment ::
The CDC recommendation for chancroid is a single oral dose (1 gram) of Azithromycin, or a single IM dose of Ceftriaxone, or oral Erythromycin for seven days.
Did you know ?
Chancroid has been known to humans since time of ancient Greeks
Chancroid in Women
Chancroid in Men
-is a common sexually transmitted disease (STD) caused by a bacterium.
Causes ::
People get chlamydia by having sex with someone who has the infection. “Having sex” means anal, vaginal, or oral sex.
Treatment ::
Chlamydia can be easily treated and cured with antibiotics.
Did you know ?
Chlamydia is known as a "silent" disease because about 75 percent of infected women and about 50 percent of infected men have no symptoms.
Chlamydia in Women
Chlamydia in the eye
-a venereal disease involving inflammatory discharge from the urethra or vagina.
Causes ::
Gonorrhea is almost always sexually transmitted.
Treatment ::
Gonorrhea is treated with antibiotics. A variety of treatments are available for gonorrhea that usually involve a single injection or a single dose of oral medication (pills).
Did you know ?
In 2010, nearly 10,000 cases of gonorrhea were reported in Canada.
Gonorrhea on the eyes of a baby
Gomorrhea in the mouth
- is an inflammation found in many diseases.
Causes ::
-Animal or insect bites,
-Infections, including hepatitis
-Tuberculin skin tests
-Vaccinations
-Sun exposure
Treatment ::
In most cases, no treatment is necessary for granuloma annulare. Most lesions disappear within a few months, and rarely last more than two years.
Did you know ?
Granuloma inguinale is rare in the United States. However, it is common in certain less developed countries, including India, Papua New Guinea, Central Australia, and Southern Africa.
Granuloma on a hand
-is a highly contagious disease spread primarily by sexual activity, including oral and anal sex.
Causes ::
caused by the spirochete bacterium Treponema pallidum subspecies pallidum.
Treatment ::
The first-choice treatment for uncomplicated syphilis remains a single dose of intramuscular penicillin G or a single dose of oral azithromycin
Did you know ?
Once Syphilis starts to affect the brain, without treatment it's 100% fatal and for years there was no treatment available.
Patient with tertiary (gummatous) syphilis.
Reddish papules and nodules over much of the body due to secondary syphilis
- is a fungal infection
Causes ::
caused by a yeast-like fungus called Candida albicans.
Treatment ::
The most common method of treating oral thrush is to use a medicated liquid that is swished around the mouth and swallowed, or a lozenge that is sucked, dissolved in the mouth, and swallowed.
Did you know ?
it has infected 370 million people and is responsible for almost 1 million deaths annually.


- is a viral disease.
Causes ::
caused by a group of herpes viruses, that may produce cold sores, genital inflammation, or conjunctivitis.
Treatment ::
Although there is no cure for herpes, treatments can relieve the symptoms.
Did you know ?
it is more easily transmitted from men to women than from women to men.
Herpes on the face
-is a lentivirus.
Causes ::
causes acquired immunodeficiency syndrome, a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.
Treatment ::
There's no cure for HIV/AIDS, but a variety of drugs can be used in combination to control the virus.
Did you know ?
HIV/AIDS remains one of the world's most significant public health challenges, particularly in low- and middle-income countries.
Causes ::
caused by a virus that was first described in 1817.
Molluscum in the face
- is a DNA virus from the papillomavirus family that is capable of infecting humans.
Treatment ::
There is no cure for the virus itself, but many HPV infections go away on their own. In fact, about 70 percent to 90 percent of cases of HPV infection are cleared from the body by the immune system.
Signs & Symptoms
What are the symptoms of HPV?
In many cases, HPV produces no symptoms. When they do occur, the most common symptom is the presence of warts in the genital area.
