Air Purifiers

i am a student nurse.. i was clearing the things being used to a baby (20 days old), diagnosed with bacterial meningitis (specific bacteria, not identified yet). I was in a hurry when i was accidentaly pricked by a needle being used to the baby. I

I saw blood on my finger, i immediately squeezed my finger hoping all the blood being in contact w/the needle will come out.. i then washed my hands and applied sanitizer. Though i didn’t feel anything wrong in my body (yet), i am still very worried because some diseases like STDs can be easiy transmited by needle pricks.. i checked the internet, most says bacterial meningitis will be transmitted through direct contact w/patient (air droplets). None mention about needle pricks, u guys have any idea?

I need advise please.. i’m very worried! thanks!
