ABSTRACT

Background. Risk factors associated with the human immunodeficiency virus were identified since the beginning of the epidemic. However, other unusual ones, were considered unlikely because they didn't occur in situations or places related to known risk behaviour such as person to person transmission, domiciliary transmission and from health giver to patient among others. Objectives. To bring concepts about transmission mechanisms up to date for revision by scientific literature given their importance in the prevention and control of HIV/AIDS and to emphasise the importance of observing universal preventatiive precautions. Results. Nowadays, it is important to consider the titres/titles of HIV, the contagiousness of the virus and the integrity of the mucous linings in the transmission of HIV by oral sex, hospital transmission and person-to-person transmission have been reported and evaluated by molecular biological studies. The proportion of accidental transmission in the workplace in Mexico is similar to that of the United States. The initial report of HIV infection in a dentist's patient in 1990, has been completed by phylogenetic analysis to give a total of six patients. More recently, the cause of an patient arthopaedic surgeon who infected a patient in a occupational accident was reported. Conclusions. The pracrtice of oral sex is actually considered to be a risk factor for HIV infection, which becomes important in the present since the practice of oral sex seems to be more accepted by society than anal sex therefore the promotion and education of safe sex must be emphasised. So far there is no conclusive evidence of hospital transmission or person-to-person transmission other than at the molecular epidemiological level, however, the occurrence of the presented cases give value to the possibility of their occurrance. In the light of this, it is important to observe, maintain and reinforce the universal preventative precautions in the control of HIV infection.
