Transmission & prevention of HIV --

How is HIV transmitted ?

HIV is found in substantial number in semen, blood & vaginal secretions. Hence if any of theses secretions enter the body of a healthy person, then the infection can be transmitted.

Since semen & vaginal secretions are sexual fluids, unprotected penetrative sex with HIV infected person is an important route of transmission. This is the predominant route of transmission of the infection.

Blood can be gain entry in another body during blood transfusion or due to sharing of used needles. The latter is common in intravenous drug abusers. It can also occur if needles & syringes are used without proper sterilization in the hospitals.

HIV can also be transmitted from the mother to the fetus.

Can kissing lead to HIV transmission ?--

No the concentration of HIV in saliva is very low. Large quantities of saliva are unlikely to be exchanged in kissing. Even if the saliva contains HIV, it does not get transmitted unless there are some cuts/ bruises in the mouth.

Hence kissing is unlikely to lead to HIV transmission.
