  • Slide 51 - Syphilis Symptoms Syphilis is a multi-stage disorder: Primary stage - painless, infectious chancre Several days-few months after infection Genitals, mouth, rectum, other areas Sometimes there is no chancre Ulcer heals; many may think there is no problem Illustration: male (MayoClinic) Photos: oral, male, female, mix (CDC, Univ. of South Carolina Integrated Biomedical Sciences; University of Quebec; Cincinnati STD/HIV Prevention Training Center; istdpictures.com)
  • Slide 52 - Syphilis Symptoms Secondary stage Infectious rash 3-6 weeks following infection Hands, soles of feet; other areas Fever and flu-like symptoms may also be apparent Rash typically heals after several weeks More photos, including rash pix (Hardin Library, CDC) Condylomata Lata Wart-like lesions (on female, male, CDC)
  • Slide 53 - Syphilis Symptoms Latent Stage Infection hides in body, often central nervous system Infected person can remain in this stage for years There may be no symptoms for a long time Disease begins to attack organs Latent further divided into early, late, or unknown stages based on when infection occurred Late/Tertiary Stage Severe symptoms develop: paralysis/numbness; blindness; heart disease; dementia
  • Slide 54 - Syphilis Treatment Penicillin or other antibiotic Communicate with all sex partners regarding syphilis Refrain from sexual activity until infection is gone Condoms may help prevent syphilis transmission
  • Slide 55 - Syphilis Complications Late-stage syphilis If blood vessels affected, stroke,other cardiovascular incident may occur Nervous system (brain) damage Al Capone Apparently knew, did not treat Became confused, disoriented
  • Slide 56 - Syphilis PBS “Frontline:” The Children of Rockdale County Tuskegee Syphilis Experiment Began in 1930s ~400 African American males with syphilis observed When penicillin became available, not provided Ended in 1972 as a result of a news leak; settlement in 1974; Al Gore overview (1:35, usrf.org) Formal apology did not occur until 1997 (1:10, usrf.org) Over 100 individuals died from syphilis complications PBS “Nova” - “The Deadly Deception” (1:30-9:44/20:41/22:13/23:45/ 26:39/31:08 via Youtube)

  • Slide 60 - Genital Herpes, Physician Visits, 1966-2011
  • Slide 61 - About Herpes Transmission via vaginal, oral, anal sex Transmission of virus can also occur through fingers (touching a sore, then touching a membrane) Transmission of virus possible when no sores present Transmission to fetus possible, but not typically if herpes was contracted before pregnancy If pregnant woman contracts herpes toward end of pregnancy, transmission to fetus more likely If pregnant woman has active herpes, Cesarean performed Transmission may occur outside body contact, but no proof
  • Slide 62 - Herpes Symptoms Most common symptom is blisters First (primary) outbreak occurs within a few weeks of contact May continue for a couple weeks, longer for those with compromised immune system May feel painful, itchy, tingle/burn
  • Slide 63 - Herpes Symptoms Flu-like symptoms (headache, fever, swollen lymph glands, muscle aches, etc) Burning during urination About.com video (1:45) Illustration (catalog.nucleusinc.com) Photos: oral lesion, male, female (lib.uiowa.edu, dermnet.com, www.stdservices.on.net)
  • Slide 64 - Herpes Symptoms Many people (numbers difficult to estimate; some references cite 25-60%) asymptomatic Recurring outbreaks usually less severe Episodes are shorter Episodes become less frequent 50-80% (HS-1 vs HS-2) will experience recurrence Asymptomatic shedding of virus less prevalent
  • Slide 65 - Herpes Treatment No cure; herpes simplex remains in body for life 2009 research revealed re HS-1 Published in Nature Immunology A cellular combat process against HS-1 has been identified Infected cell can stimulate immune system to fight HS-1 “Hidden” infected cells can show themselves when infectious state thrives (low-grade fever) Information from work might be used to develop therapies HS-1, HIV, other viral infections Information from work might be used to keep virus hidden
  • Slide 66 - Herpes Treatment Symptoms are treatable Antiretroviral medications, usually prescribed for genital herpes, may also be prescribed for oral cold sores Supplements (lysine) Abreva Avoid touching sores Keep affected area clean Wash hands Communicate with all sex partners regarding herpes Refrain from sexual activity until outbreak is gone Condoms may help prevent herpes transmission (during outbreak blisters are highly contagious)
  • Slide 67 - Herpes Complications In otherwise healthy individuals, herpes does not cause serious complications Among those with compromised immune systems, herpes outbreaks can be very severe, last a long time Having herpes increases one’s vulnerability to HIV
  • Slide 68 - HIV and AIDS
  • Slide 69 - About HIV and AIDS Human Immunodeficiency Virus (HIV) causes Acquired Immune Deficiency Syndrome (AIDS) Incidence: WA, 2011: 514 new cases (1/3 = later stage) King County - HIV: ~300-400 each year; AIDS: ~100-200; ~6,500 to 8,000 living with HIV (WA State/Seattle-King County HIV/AIDS Epidemiology Report, 1st Half of 2011) US: 56,300 new HIV cases in 2006 (CDC, presentation)
  • Slide 70 - About HIV and AIDS Transmission via vaginal, oral, anal sex, needle sharing, mother to infant, rarely via blood transfusions or healthcare settings One 1990s incident of transmission between infected health care worker (dentist) and five patients Per CDC (2011), 57 cases of HIV transmission to healthcare workers through 2001,with no cases since 1999
  • Slide 71 - About HIV and AIDS HIV not transmitted via: Toilet seats Mosquito bites Sharing eating utensils Food Shaking hands, hugging Donating blood No scientific evidence HIV is transmitted other ways
  • Slide 72 - About HIV and AIDS Currently, HIV does not survive well in the environment HIV found in sweat, tears, saliva - but no documentation of transmission 2009: pre-chewed food thought to cause three HIV transmission between caregivers and children Blood in saliva (bleeding gums) An issue where pre-chewing food for infants is common (Africa) No known risk in the workplace, school, etc. AIDSinAfrica.com HIV and AIDS in the World (PBS)
  • Slide 73 - HIV Symptoms Symptoms unreliable in diagnosing HIV First symptoms experienced may be flu-like (fever, headache, muscle aches, fatigue, etc) Symptoms may occur days to weeks after infection Symptoms may last days or weeks Diagnosis requires testing for HIV antibodies
  • Slide 74 - HIV Symptoms After early flu-like symptoms disappear: There may be no symptoms for a long time Virus replicates As HIV leads to AIDS: Boils, warts, herpes infections, skin rashes Fatigue Diarrhea Frequent fevers Yeast infections Weight loss
  • Slide 75 - HIV Treatment Medications provided as a “cocktail” Antiretroviral drugs interfere with HIV’s ability to reproduce Entry inhibitors may prevent HIV from entering a cell Reverse transcriptase inhibitors interfere with the beginning of HIV’s reproductive cycle Protease inhibitors interfere with the end of HIV’s reproductive cycle Integrase inhibitors interferes with HIV genetic material moving into a CD4 cell, halting replication Research continues on vaccine Clinical trial results 2010 - antiretrovirals may prevent HIV transmission
  • Slide 76 - HIV Complications AIDS Status of HIV is monitored through CD4 count and viral load every few months If HIV progresses, CD4 count reduces, viral load increases Normal CD4 often referenced as 500-1000 AIDS diagnosis requires CD4 of 200 Low viral load ~40-500 High viral load ~5,000-10,000 (can be higher)
  • Slide 77 - AIDS Symptoms AIDS diagnosis includes specific white cell count and diagnosis of one of over two dozen opportunistic infections Nearly all organs are affected Respiratory problems Seizures, lack of coordination Confusion, forgetfulness Gastrointestinal pain, cramping, vomiting Weight loss Fever Severe diarrhea
