Herpes Simplex 2

 

1. SIMPLEXVIRUS herpes simplex virus 2 (hsv-2)2. - Herpes simplex (type 2 is often associated with genital herpes)

 

    - Herpes simplex encephalitis

    - Neonatal herpes simplex  

3. - Resembles many small hexagon/pentagons joined together

    - Has a distinct "star shape"-like imprint

4. Direct and sometimes possible indirect contact between infected area, can be shed from person to person without active sores, childbirth

5. Use of condoms, valaciclovir (antiviral drug), avoid sex while you have hsv blisters, mangagement of stress, adequate sleep/rest

6. Skin and nerve cells

7. tingling sensation in infected area, which later swells up and causes pain, blisters, sports, or red bumps, inflammation, discomfort

8. Naturally builds up immunity over time (antibodies)

9. - Herpevac - Still undergoing clinical testing. 70% effective in women. No effect on men

    - Aloe Vera - helps to shroten outbreaks, but not by a lot. Roughly 13% effectiveness

10. - Once a person is infected with hsv-2, the virus never truly goes away, but remains latent in clel bodies of nerves in the area

      - It is estimated that one in four people in the U.S have hsv-2    

      - About 90% of infected people don't know that they're infected

      - Blisters usually appear about 12 days after the inital infection

      - hsv-2 is not hereditary (it doesn't transfer through sperm or egg)

Herpes Simplex 2

 

- the scientific name is Herpes Simplex Virus (HSV-2)

 

- diseases and disorders caused by Herpes:

 

• Herpes simplex encephalitis (a serious brain infection)
• Neonatal Herpes simplex (HSV transmission from mother to a child)

 

- a primary infection usually occurs through sexual genital contact with an infected individual and primarily associated with genital and anal lesions

 

- Basic Structure:

 

 

 

 

 

- HSV-2 can be shed through skin-to-skin contact only

- wearing a condom is highly recommended

- condoms are not completely effective because:

 

• some blisters may not be covered by the condom
• free virus in female vaginal fluid may infect the base of the penis
• testicles are not covered by the condom

 

- type of body cells attacked are the skin and nerve cells

 

- symptoms:

 

•  tingling/itching sensation in affected location

• emergence of a raised or swollen area on skin
• swollen area is painful in general, but acutely sore when touched, stretched or moved
• sores emit virus laden fluid and scabs over
• once scabbed over, lesions heal within 7-10 days
• patients experience fatigue, headaches, and peculiar twitching sensations in nerves that lead to the area of outbreak

 

- body defends itself by:

 

• dendritic cells of the immune system travel from the blood to peripheral tissue to capture foreign antigens (the HSV virus)

 

- no cure for HSV

- anti-viral medications to control herpes outbreaks:

 

• aciclovir (Zovirax)
• valaciclovir (Valtrex)
• famciclovir (Famvir)

 

- these treatments work by slowing the replication rate of the virus, providing greater opportunity for immune response to intervene

 

- 5 interesting facts:

 

• Herpes can affect any part of the body. If you touch a genital herpes sore and then touch another part of your body, you can potentially spread the virus
• There are 8 different Herpes viruses
• The incidence of HSV-2 in the US is estimated between 25-30 percent or about 1 in 4 adults
• Most infected people (up to 90%) don't know they're infected because they have very mild symptoms, or show no symptoms at all
• Herpes can be passed down from a mother to her child by neonatal herpes simplex
