  1. Humans Herpesviruses Type 1(HHV1)--colds sores and fever blisters?
    • A) Transmission
    • -Direct Contact
    • B) Symptoms
    • -Painful, itchy skin lesions, usually on or around the lips; may be accompained by flu-like symptoms (malaise, fever, muscle pain)
    • D) Treatment
    • - Antiviral med limits duration of outbreak and amount of virus shed, but does not cure.
    • E) Prevention
    • - Avoid contact with individuals who have active lesions
  2. HHV 2--Genital herpes?
    • A) Transmission
    • - Dircet contact
    • B) Symptoms
    • - Painful, itchy skin lesions, usually inthe genitalia
    • C) May occur in oral area, usually as result of oral sex
    • D) Treatment
    • - Antiviral med limits duraton of outbreak and amount of virus shed, but does not cure.
    • E) Prevention
    • - Avoid contact with individuals who have active lesions; prevent sexual transmission via monogamy, abstinence. Sexuak transmisson reduce by abstention from sex during active outbreak.
  3. HHV 3--Chickenpox/shingles?
    • A) Overall
    • - Varicella= Chickenpox
    • - Zoster= Shigles
    • B) Transmission
    • - Aerosol or contact with fluid in lesions (may enter eyes).
    • C) Symptoms
    • - Chickenpox- Fever, malaise, itchy skin lesions. Lesions apper about 2-3 weeks after infection, last few days to 2 weeks. Lesions begin as macules, progress to papules, then vesicles; vesicles then turn cloudy and dry up.
    • D) Virus can be latent in neurons; shingles- during stress or immune suppression, virus particles released and travel to skin, cause infection---> shingles. (1) Shingles- pain at site followed by rash, vesicles; Pain in area can remain for long times after healing of lesions. Rash may break out on one side of trunk, in area served by the affected neurons.
    • E) Treatment
    • - Chickenpox- if not complications. supportive care is enough.
    • - Shingles- supporive care and bed rest.
    • F) Prevention
    • - Chickenpox vaccine
  4. Common Cold Viruses?
    • 2. Transmission
    • - Aersol, fomites (these viruses survive will outside host), ingestion of contaminated food or water.
    • 3. Symptoms
    • -Runny nose, pharngitis, cough, headache.
    • 4. Treatment
    • - Supportive care
    • 7. Viral pnuemonia
    • a) Many possible causes
    • c) Treatment
    • - Supportive care, antiviral medication may be used; antibiotics NOT effective against the viruses.
  5. Paillonma viruses?
    • 1. Cause warts, some tumor cancers (HPV= Human Papilloma Virus)
    • 4. Transmission
    • - Direct contact and via fomites
    • - Genital warts by sexual transmission
    • 5. Symptoms
    • - epithelial growths, often painful
    • - depending on manner of transmission, may occur on fingers, feet, trunk, genitalia.
    • 7. Treatmen
    • - removal with caustic chemicals, freezing, cauterization or surgery; cover with duct tape until gone.
    • 8. Prevention
    • - Genital warts/HPV cancer: Abstinence, monogamy, HPV vaccine.
    • - Condom use does not seem to be very effective
  6. Influenza?
    • 4. Transmission
    • - Aerosol or via fomites
    • 5. Symptoms
    • - Fever, cold, cough, headache, malaise, myalgia (muscle aches0, inflamed respiratory membs.
    • 6. Treatment
    • - Supportive care, mostly; antiviral meds may be used
    • 7. Prevention
    • - Yearly vaccine (due to rapid mutation rate of these viruses, the vaccine has to be re-done every year)
  7. Measles?
    • 2. Transmission
    • - Aerosol
    • 3. Symptoms
    • - Fever, sore throat, dry cough, conjunctivitis; after 2 days, lesions apper on mucous membrane of mouth; then red, raised lesions appear on head and spread over body.
    • 4. Treatment
    • -Rest, supportive care
    • 5. Prevention
    • - Vaccine (first "M" of MMR vaccine)
  8. Mumps?
    • 2. Transmission
    • - aerosol

    • 4. Treatment
    • - Supportive care, rest
    • 5. Prevention
    • - Vaccine ("R" part of MMR)

    • - Paralytic polio- symptoms of minor polio followed by CNS infection resulting in paralysis
    • 5. Treatment
    • - For paralytic polio, repiratory support- mechanical ventilation
    • 6. Prevention
    • - IPV- imactivated Polio Vaccine. Developed first, and now the current vaccine used
  11. Hepatitis?
    • These viruses all infect the liver, but belong to different viral families
