A vast majority of HIV
transmissions occur via unprotected sexual relations & sharing needles.
Hiv is transmitted by infected bodily fluid coming into contact w/open wounds
. In theory a pen contaminated w/infected bodily fluids could transmit HIV if it contacted/created an open wound. This scenario would be very unlikely. Anyone who thinks they've had direct contact w/hiv should request testing.
