Q

Explaining herpes to patient

A
  1. Most (up to 75%) 1st-episode infections are picked up by an asymptomatic partner
  2. 1st-episode infections may be asymptomatic or, like in your case, cause painful ulcerating genital lesions
  3. These tend to heal over 2 weeks and the medications we give will help to reduce the severity
  4. Once it all heals this virus tends to remain dormant in your nerves
  5. When your immune system is a bit down (ie. head-colds, menstruations or stress) this virus can “sneak out” and cause recurrent infections
  6. These recurrent infections may be asymptomatic or cause an outbreak of similar lesions on your genitals but these are almost always milder than the 1st time
  7. Sometimes the recurrence is preceded by a funny tingling or burning sensation on your genitals, which is known as the prodromal period
  8. It’s important to realise that you are infectious during the prodrome and when the lesions are present so it’s important to avoid all sexual contact until it has resolved
  9. It’s also wise to always practise safe sex by encouraging any partners to wear a condom as you don’t always know when you are having a recurrence!

  5. Will not dislodge or abort an established, not teratogenic
  6. Chance of pregnancy also dependent on stage of cycle
  7. Insertion of IUCD w/i 5 days also option, failure rate of 1%->not choice in nulliparous with risk of STD
