Spit/Blood in mouth

[1986Harry]

Today I was talking to a security guard asking for directions and he came really close to my face and shouted at me. Whilst doing so his spit landed straight on my tongue. I know that people say saliva is not a risk but what if there is blood in a persons saliva - surely it is a risk then. it was a large amount of spit. And I didn't see the saliva I felt it - so i don't know if it looked red.
The man was african. 1 in 25 Africans in the UK have HIV.
I have sores and cuts all over my tongue as a result of orthodontic work that I had done two days ago. So the tongue would offer as an entry route to my blood stream this way right?
I need some information on this as I don't know what to do and I am freaking out.

Yes, plus saliva is not infectious and contains over a dozen different enzymes and proteins that inhibits HIV transmission.

Thanks for the response. But even if the saliva left his mouth and went directly into mine straight away - does this still mean it was outside too long?

You never had an exposure.

HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.

HIV is transmitted by;
Unprotected penetrative anal and/or vaginal sex
Sharing works with other IV drug users
Mother to child
