ANSWER b
- Signs and symptoms of recurrent episodes (when they occur) tend to be milder and heal much more quickly, typically within two to twelve days.
- If the first episode produced fairly mild symptoms, then later recurrences usually won’t be more severe. But, as noted earlier, when genital herpes recurs after a first episode, it doesn’t always cause recognizable signs and symptoms.
- Some people have recurrent outbreaks with the so-called “classic” blisterlike herpes lesions that crust over, or with painful sores. In recurrent herpes, however, this process usually takes about half the time it does in first episodes, herpes is capable of reactivating without producing any visible lesions This is called asymptomatic reactivation.
