Blood on finger and nose-picking

Hello,
I went to a supermarket for buying some stuff. While i took a plaster out of the shelf, a box with wound cleanser fell on the floor.
I picked it up and stowed it away. I saw, that it was opend but i didn´t react to it.
Later i saw, that i had some blood on my Thumb.
Meanwhile i picked my nose. So my right digit came in contact to the thump with the blood an got into the nose for a few more times.
I went back to the store an found red spots on the opend box.
There is a chance, that i got blood into the nose.
I´m worried, because the store opend a few minutes before i bought the plaster. So the blood was quite fresh.
Did i have catched HIV by this event?

HIV risks for adults are:
1) having unprotected, penetrative, anal or vaginal sex, or
2) sharing intravenous needles (with IV drug users)

NOTHING else you can think of is a risk for HIV, including the event you mentioned.  Blood, once outside of the body, is no longer infectious.  If a person could get infected with HIV in this manner, everyone in the world would have HIV by now.

There is no detail you could add to this event that would make it a risk for HIV.  However, touching an object you find in public, and then touching mucous membranes like those found in your nose, is a good way to contract serious viral illnesses like the flu.
