1 Warm Up Name some STDs that we have talked about and what some of their side effects are.

2 STDs and HIV Lesson 37

3 Objectives Analyze the importance and benefits of abstinence as it relates to the prevention of STDs and pregnancy Discuss abstinence from sexual activity as the only method that is 100% effective in preventing STDs Develop and analyze strategies related to the prevention of communicable disease such as STDs Identify symptoms and treatments for some common STDs Identify community health services for getting help with prevention and treatment of STDs Explain how HIV affects and destroys the immune system Identify behaviors known to transmit HIV Analyze the relationship between unsafe behaviors, refusal skills and the risk of HIV

4 HPV Human papillomavirus Most common STD in the United States
Virus that can cause genital warts or asymptomatic infections Most common STD in the United States 30 different types can infect the genital area No treatment Almost all cases of cervical cancer are caused by certain types of HPV HPV can cause cancers of the penis and anus as well

5 Genital Warts Pink or reddish warts with cauliflower-like tops that appear on the genitals, vagina or cervix Appear 1-3 months after becoming infected with HPV Highly contagious Spread by any form of sexual contact with an infected person Once infected, a person carries the virus for the rest of his/her life Infants born to an infected female may develop warts in their throats, obstructing breathing and becoming fatal

6 Chlamydia Bacterial infection that affects the reproductive organs
40% of cases in teens 15-19 Asymptomatic in 75% of females and 50% of males Treated with antibiotics If not treated can lead to Pelvic Inflammatory Disease Chronic pelvic pain Infertility Can cause premature birth Infants born to infected mothers may develop eye disease or pneumonia

7 Genital Herpes STD caused by the herpes simplex virus
Type 1 causes cold sores Type 2 causes genital sores Blister-like sores appear in the genital area periodically Individual may be asymptomatic for a period of time, unaware that he/she is infected No cure—once infected you are infected for life Potentially fatal for infancts

8 Gonorrhea Bacterial STD that usually affects mucous membranes
Symptoms in males Discharge from the penis Painful urination Diagnosis is males made by staining and examining the discharge under a microscope 50% of females are asymptomatic Diagnosis in females made by swabbing the cervix and growing the organisms in a laboratory Treated with antibiotics Can lead to infertility May spread to the bloodstream, causing permanent damage to joints Infants born to infected mothers may contract eye infections that cause blindness

9 Trichomoniasis STD caused by microscopi protozoan that results in infections of the vagina, urethra and bladder Females may be asymptomatic, but vaginitis may result Inflammation of the vagina characterized by discharge, odor, irritation and itching Diagnosed by microscopic analysis of discharge Males usually show no symptoms, but if they do occur itching, burning when urinating and discharge are common

10 Syphilis STD that attack many parts of the body and is cause by a small bacterium called a spirochete First sign is a painless, reddish sore Disease can damage internal organs, including heart, liver, nervous system and kidneys If untreated, the person is at risk of paralysis, convulsions, blindness and heart disease Infant born to an infected mother can have a damaged nervous system and could potentially die from the effects

11 HIV Human Immunodeficiency Virus
Virus that attacks the immune system Results in AIDS (Advanced stage of HIV infection) Acquired Immune Deficiency Syndrome Disease in which the immune system of the patient is weakened How it works HIV invades certain cells of the immune system, causing them to produce copies of themselves. As the virus takes over more cells and reproduces it grows while the number of while blood cells decreases. This makes the immune system less capable of preventing infections and cancer Body becomes susceptible to common infections and opportunistic infections Infections that occur in individuals who do not have healthy immunes systems Difficult to treat Progressive disease Destroys cells of immune system over months or years No cure Certain drugs can help to slow down the progression, however new strains are emerging that are resistant to these drugs

12 How HIV is Transmitted Through blood, semen, vaginal secretions and breast milk Sexual Intercourse During any type of sexual intercourse Sharing Needles Mother to baby Passed through the umbilical cord or during delivery Passed through nursing Can’t be transmitted through food, doesn’t survive well in the air or on surfaces such as toilet seats or telephones

13 Stages of Infection ½ of all person develop symptoms 3-6 weeks after becoming infected. Symptoms may include fever, rash, headache, body aches and swollen glands. Symptoms usually disappear within a week to a month and are often mistaken for another viral infection Asymptomatic stage Period of time during which a person infected with HIV has no symptoms 6 months to 10 years or more Virus continues to grow and person can transmit it to others Symptomatic stage Stage in which a person has symptoms as a result of a sever drop in immune cells Swollen glands, weight loss, yeast infections AIDS Severely damaged immune system Appearance of one or more opportunistic infections or illnesses Attack of brain cells, causing difficulty in thinking and remembering

14 Detecting HIV EIA Western Blot Test
Test that screen for the presence of HIV antibodies May give inaccurate results for 2 reasons Developing antibodies takes time Certain health condition can cause a false positive Western Blot Test Most common confirmation test for HIV 100% accurate

15 In Conclusion, AIDS is deadly and incurable. The only 100% effective measure in prevention is abstinence—abstinence from sexual intercourse and high risk behaviors Don’t put your life in the hands of another…sometimes that trust can be your downfall If AIDS doesn’t scare you, think about all the other STDs we have mentioned. They will not only affect you, but your future partners and children. Is it worth it? Read time health pg 668…if time permits research one of the STDs mentioned (in groups) answer the following topics: Treatment, Effectiveness, Side Effects of Treatment, Long term results of the STD with and without treatment
