Dr.EWH.
My knowledge from this web site told me that HIV cannot be transmitted outside hosts. But today I faced a situation that made me not sure about the risk. Please help me.
I went to a mini-mart, near my home, to buy some snack and drinks. When I came back home (3 minutes from the mini-mart), I was picked by a sewing pin in my home. Then I clean my wound with alcohol immediately.
But the bad luck is after cleaning my wound, I noticed some blood on my cloth, my wound didn't have a lot of blood like that so I investigated where it came from and found that it came from the snack package. So my hand may be dirty of blood before the pin picked too. and the second bad luck was I touch the blood on snack package on the same finger that was picked by the pin while investigation. (The cashier was cut by the edge of snack package.) The blood on the edge of snack package was not dry that time.
My question is...
1. Could I get HIV from blood on snack package and 3 minutes later I was pick by the pin?
2. 3 minutes and wet blood and pin pick... Is it long enough that HIV will be inactive.
3. Do I have to get HIV test?
Note: blood on snack bag is only a drop of blood (about 0.5 mm.)
