Question

which can transmit hiv?
blood
saliva
sweat
tears

Explanation:

HIV is mainly transmitted through certain body fluids. Blood is a well - known medium for HIV transmission as it can carry a significant amount of the virus, especially in cases such as unprotected blood transfusions (in regions without proper screening), sharing of contaminated needles (in injection drug use), and mother - to - child transmission during childbirth (due to blood contact). Saliva, sweat, and tears generally contain very low or undetectable levels of HIV virus particles, and the virus in these fluids is usually not in a quantity sufficient to cause infection.

Answer:

Blood
