Hello
thanks for using health care magic

Saliva is known to contained antibodies against HIV but infective HIV viral particles have not yet been isolated in saliva.

It is possible to become HIV positive through ocular transmission i.e. transmission through the eye. This carries a possibility of 0.03% and the fluid has to be highly infective i.e. with high viral load.

If spit was only saliva, then it is less likely that you could become positive unless it was mixed with blood. If you did wash your face immediately the chances are further minimized.

There is possibility of becoming infected after hugging or giving a dry kiss. So you should not be worried.

However, routine screening is good to know your status. So you could do a rapid test and repeat three months and six months later.

Best regards

Trace that man who spit to you. know his hiv status. if he is seropositive than you should concern regarding that. as you have exposed to mucosa that is eye you have probability of developing aids if the person who had spit has the aids. hugging, simple kissing wont cause aids. thnx
