a smart question

Question

it is said that the hiv virus cant live a long outside the body, so how come it is possible that contaminated needles that have blood (that is outside the body) can transmit this virus

Answer

Hi,

A hollow-bore needle filled with blood is a closed environment not exposed to air. Consequently, the HIV incorporated into the living cells in the blood survives longer in the needle than if it were exposed to open air.
