I recently had an outbreak on my skin which turned out to be caused by HPV. I had it treated successfully, but because I'm abroad and don't speak the local language, I have a few questions about the condition that I didn't manage to get answers to. I'm hoping I can get some more clarity about it here. The questions are:

1) From what I've read, there is no way to cure HPV. What I'm unclear about is my infectiousness. Now that it's clear that I have contracted HPV, does that mean I will always be infectious? Or does it clear to the point where that is no longer an issue? Is there a diagnosis I can get done that would tell me whether I'm infectious or not?

2) Again, from what I've read there are many strains of HPV. I've also learnt that there is a vaccine that protects against some of the more dangerous ones. Does it make sense for me to get that vaccine? Obviously, it won't change anything about my current condition, but would it still protect against other strains that I am not currently infected with?

3) Is there a diagnosis I can get done that would tell me which strain of the virus I am infected with, so that I could know whether it's dangerous or not and also so that I could know whether a sexual partner who got an HPV vaccine would be protected or not?

4) I'm very concerned about infecting other people with this virus, even though I've been told it's relatively harmless. I don't know how I contracted it - I always use condoms, but apparently that doesn't fully protect either? What should I do to keep future sexual partners safe? Can I be "clear enough" of the infection to safely have sex (with condoms) without infecting a partner?

I've been trying to research this, but opinions I've found online vary greatly.
