I didn’t look for the article; I believe you.
I didn’t know there was second stage syphilis, or second state anything for that matter.
Scary days.
Syph also has a tertiary stage.
Well, found one article.

Found another one.
Shingles is a "second-stage" of Chickenpox. Same virus, but presents differently. Anyone who's had Chickenpox can have Shingles, but not everyone does. It's hit or miss (I think stress related). If you have Shingles, you can transmit the virus to those who've not been immunized against Chickenpox.
Since Ebola is a virus, I'd be hesitant to consider anyone who's been "cured" to be completely free of it.
