Title: Sexually Transmitted Diseases and HIV/AIDS


1
Sexually Transmitted Diseases and HIV/AIDS
  • The scary reality

2
Communicable Diseases
  • Communicable diseases- is a disease spread from
    one living organism to another through the
    environment
  • Infection- occurs when pathogens in the body
    multiply and damage.
  • Virus
  • Bacteria
  • Fungi
  • Protozoa
  • Rickettsia

3
How Diseases Spread
  • Direct contact
  • Puncture wounds
  • Child Birth
  • Contact with infected animals
  • Indirect contact
  • Contaminated objects
  • Vectors (flies, ticks, etc)
  • Contaminated food or water
  • Airborne Transmission

4
Taking Precautions
  • Wash your hands
  • Safe food preparations
  • Abstain from tobacco, alcohol, other drugs
  • Exercise, eat healthy
  • Protect yourself from vectors
  • Use insect repellent, long sleeves, avoid long
    time outdoors

5
Fighting Communicable Diseases
  • Immune System- a network of cells, tissues,
    organs, and chemicals that fights off pathogens
  • Phagocytes- white blood cells that attack
    invading pathogens
  • Antigens- substance that can trigger an immune
    response
  • Immunity- the state of being protected against a
    particular disease

6
Lymphocytes
  • Lymphocytes- special white blood cell that
    coordinate and perform many function of specific
    immunity
  • T Cells- special lymphocyte that can trigger the
    production of B cells
  • Antibody- protein that acts against a specific
    antigen

7
Immune System Memory
  • Your immune system can remember antigens that
    it has dealt with in the past.
  • Active Immunity- develops from natural or
    artificial processes.
  • Vaccine- a preparation of dead or weakened
    pathogens that are introduced to the body to
    stimulate immune response.
  • Passive Immunity- body receives antibodies from
    another person or an animal.

8
Sexually Transmitted Diseases
  • Infections that are spread from person to person
    through sexual contact.
  • Also know as sexually transmitted infections
  • Some infections are bacterial (curable), and some
    infections are viral (non-curable)

9
Sexually Transmitted Diseases
  • Many infections are asymptomatic in which the
    person show no symptoms or the symptoms are mild
    and disappear after the onset.

10
Genital HPV Infections
  • Human Papillomavirus (HPV)
  • 30 strains are transmitted through sexual contact
  • Symptoms include warts (bumps) in or around the
    genital area can cause cervical cancer
  • May go away on own, may grow, or spread, and may
    remain unchanged.
  • Warts can come back virus may remain in body

11
Chlamydia
  • Affects both women and men
  • Symptoms occur within 7-28 days of intercourse
  • Most have NO symptoms, discharge from vagina,
    bleeding between periods, burning or pain with
    urination, pain in abdomen fever and nausea,
    frequent urination

12
Chlamydia
  • Can lead to a more serious infection
  • Reproductive organs can be damaged
  • Sterility can occur
  • Mother can pass it to child during birth

13
Gonorrhea
  • Symptoms can occur 2-21 days after intercourse
  • Most have no symptoms
  • Thick yellow or white discharge, burning with
    urination and pain with bowel movement, abnormal
    periods, cramps in abdomen

14
Gonorrhea
  • Reproductive organs can be damaged
  • Sterility can occur
  • Can pass to child during birth
  • Can cause heart trouble, skin disease, or
    blindness

15
Herpes
  • Symptoms can occur 1-30 days or longer after
    intercourse
  • Many have no symptoms or mild symptoms
  • Flu- like feeling
  • Small, painful blisters around genitals or mouth
  • Itching or burning before the blisters appear,
    blisters last 1-3 weeks
  • Blisters go away, but you still have herpes.

16
Syphilis
  • 1st Stage
  • Symptoms can occur 3-12 weeks after intercourse
  • A painless, reddish- brown sore or sores on the
    mouth, sex organs, breast or fingers
  • Sores last 1-5 weeks
  • Sores go away, but you still have syphilis
  • 2nd Stage
  • 1 week to 6 months after sores heal
  • Rash anywhere on the body
  • Flu- like symptoms
  • Symptoms will subside, but you still have
    syphilis

17
Prevention
  • Abstinence is the most successful way to prevent
    the spread of sexually transmitted diseases.

18
HIV/AIDS
  • HIV (Human Immunodeficiency Virus) attacks the
    immune system.
  • The final stage of HIV is known as AIDS (Acquired
    Immunodeficiency Syndrome) in which the immune
    system is weakened.
  • 25 million people have died from the disease 40
    million people are infected with HIV/AIDS
    worldwide

19
HIV/AIDS transmission
  • Sexual intercourse
  • Sharing needles
  • From mother to baby

20
HIV Stages
  • Asymptomatic Stage- can last for 10 years
    confined to lymph nodes no outward signs
  • Middle Stage- occurs in about 40-70 of patients
  • Symptomatic stage- T cell count is between
    200-400 may experience flu-like symptoms
  • AIDS stage- T cell count drops below 200 and AIDS
    opportunistic infections have to be present
    (respiratory infection, flu, etc).

21
Female Reproduction
  • The external reproductive organs, known as, the
    vulva include the mons pubis, labia majora, labia
    minora, vaginal opening, and clitoris.

22
Female Reproduction
  • Mons Pubis if the mound of fatty tissue that is
    located in the front of the body
  • Labia Majora fatty folds on either side of the
    vaginal opening oil and sweat glands provide
    moisture and lubrication.
  • Labia Minora smaller folds within the majora
    that contain oil glands and blood vessels
    protection from pathogens into the body.
  • Vaginal Opening hymen is located here allows
    for menstrual flow any sperm that is released
    into the opening may travel through the hymen and
    become fertilized. The urethra, which is how
    urine is excreted is also located here.

23
Internal Female Reproduction
  • Vagina an elastic, muscle- lined tube 3-4 inches
    long also known as the birth canal menstrual
    flows exits from this space.
  • Cervix neck of the uterus dilates during child
    birth glands that secrete mucus for lubrication
  • Uterus hollow, muscular organ that receives and
    holds fertilized ovum during pregnancy shaped
    like an upside down pear nourish fetus
  • Fallopian Tube tubes on each side of the uterus
    that connects the uterus to the region of the
    ovaries
  • Ovaries two female sex glands that produce
    mature ova and female hormones

24
Female Reproduction
  • Ovulation the releasing one mature ovum each
    month into a fallopian tube
  • Menstruation process of shedding the uterine
    lining range in 28 day cycles
  • Amenorrhea lack of periods by the age of 16
  • Toxic Shock Syndrome (TSS) rare disease caused
    by bacteria flu- like symptoms super tampons
    are believed to be responsible
