1Sexually Transmitted Diseases and HIV/AIDS The scary reality
2Communicable Diseases Communicable diseases- is a disease spread from one living organism to another through the environmentInfection- occurs when pathogens in the body multiply and damage.VirusBacteriaFungiProtozoaRickettsia
3How Diseases Spread Direct contact Indirect contact Puncture wounds Child BirthContact with infected animalsIndirect contactContaminated objectsVectors (flies, ticks, etc)Contaminated food or waterAirborne Transmission
4Taking Precautions Wash your hands Safe food preparations Abstain from tobacco, alcohol, other drugsExercise, eat healthyProtect yourself from vectorsUse insect repellent, long sleeves, avoid long time outdoors
5Fighting Communicable Diseases Immune System- a network of cells, tissues, organs, and chemicals that fights off pathogensPhagocytes- white blood cells that attack invading pathogensAntigens- substance that can trigger an immune responseImmunity- the state of being protected against a particular disease
6LymphocytesLymphocytes- special white blood cell that coordinate and perform many function of specific immunityT Cells- special lymphocyte that can trigger the production of B cellsAntibody- protein that acts against a specific antigen
7Immune System MemoryYour 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.
8Sexually Transmitted Diseases Infections that are spread from person to person through sexual contact.Also know as sexually transmitted infectionsSome infections are bacterial (curable), and some infections are viral (non-curable)
9Sexually Transmitted Diseases Many infections are asymptomatic in which the person show no symptoms or the symptoms are mild and disappear after the onset.
10Genital HPV Infections Human Papillomavirus (HPV)30 strains are transmitted through sexual contactSymptoms include: warts (bumps) in or around the genital area; can cause cervical cancerMay go away on own, may grow, or spread, and may remain unchanged.Warts can come back; virus may remain in body
11Chlamydia Affects both women and men Symptoms occur within 7-28 days of intercourseMost have NO symptoms, discharge from vagina, bleeding between periods, burning or pain with urination, pain in abdomen; fever and nausea, frequent urination
12Chlamydia Can lead to a more serious infection Reproductive organs can be damagedSterility can occurMother can pass it to child during birth
13Gonorrhea Symptoms can occur 2-21 days after intercourse Most have no symptomsThick yellow or white discharge, burning with urination and pain with bowel movement, abnormal periods, cramps in abdomen
14Gonorrhea Reproductive organs can be damaged Sterility can occur Can pass to child during birthCan cause heart trouble, skin disease, or blindness
15Herpes Symptoms can occur 1-30 days or longer after intercourse Many have no symptoms or mild symptomsFlu- like feelingSmall, painful blisters around genitals or mouthItching or burning before the blisters appear, blisters last 1-3 weeksBlisters go away, but you still have herpes.
16Syphilis 1st Stage: Symptoms can occur 3-12 weeks after intercourse A painless, reddish- brown sore or sores on the mouth, sex organs, breast or fingersSores last 1-5 weeksSores go away, but you still have syphilis2nd Stage:1 week to 6 months after sores healRash anywhere on the bodyFlu- like symptomsSymptoms will subside, but you still have syphilis
17PreventionAbstinence is the most successful way to prevent the spread of sexually transmitted diseases.
18HIV/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
19HIV/AIDS transmission Sexual intercourseSharing needlesFrom mother to baby
20HIV StagesAsymptomatic Stage- can last for 10 years; confined to lymph nodes; no outward signsMiddle Stage- occurs in about 40-70% of patientsSymptomatic stage- T cell count is between ; may experience flu-like symptomsAIDS stage- T cell count drops below 200 and AIDS opportunistic infections have to be present (respiratory infection, flu, etc).
21Female ReproductionThe external reproductive organs, known as, the vulva include the mons pubis, labia majora, labia minora, vaginal opening, and clitoris.
22Female ReproductionMons Pubis: if the mound of fatty tissue that is located in the front of the bodyLabia 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.
23Internal 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 lubricationUterus: hollow, muscular organ that receives and holds fertilized ovum during pregnancy; shaped like an upside down pear; nourish fetusFallopian Tube: tubes on each side of the uterus that connects the uterus to the region of the ovariesOvaries: two female sex glands that produce mature ova and female hormones
24Female ReproductionOvulation: the releasing one mature ovum each month into a fallopian tubeMenstruation: process of shedding the uterine lining; range in 28 day cyclesAmenorrhea: lack of periods by the age of 16Toxic Shock Syndrome (TSS): rare disease caused by bacteria; flu- like symptoms; super tampons are believed to be responsible
