HIV/AIDS is the most dreaded disease on this earth which has accounted for a number of deaths.
When we hear about HIV/AIDS, a lot of questions come to mind including how it is transmitted. From a biological point of view, a person can easily contract the disease through bodily fluids such as semen, breast milk and blood.
The virus can't live on the saliva, tears or sweats as cited by Deborah Weatherspoon, PhD, RN, CRNA, a professor of nursing at Walden University
Kissing is all about exchanging saliva and therefore a person can't get the malady from an HIV positive person because of the reason outlined above.
If we base our reasoning on conditions for HIV transmission, you will realize that kissing is regarded as among the most ineffective ways of spreading it.
For instance, there must be body fluids in which the virus can survive. As stated earlier, these fluids include semen and such. With regards to saliva, its high antimicrobial defences make it impossible for the virus to survive.
Moreover, there must also be sufficient levels of virus in the body fluids. In this case, saliva has insufficient levels and therefore the virus can not thrive on it.
However, when the HIV positive person happens to have open wounds in his or her mouth, the other person can acquire the virus through kissing but only if they have incisions in their mouth as well.
