**5. Parental, saliva and other body fluids**

Prior to Groopman and Greenspan (1996) report of oral manifestation of AIDS which increases the potentials of HIV transmission through several lesions which form exists for virus into the saliva, it was assumed that about 10% of both free virus and infected cells report in saliva were not very important in the spread of HIV (Groopman et al., 1984).

Dean et al (1988) and Mundy et al (1987) reported none or low level of pathogens in urine, sweat, breast milk, branchoalvolar lavage fluid, amniotic fluid, synovial fluid, faeces and tears which were not thought to be important source in virus transmission (Fujikawa et al., 1985), but this assumption has also changed with the report of Groopman and Greenspan (1996); Amory et al. (1992); Scarlatti (1996); van da Perre et al. (1991). Though not a natural source of HIV transmission, cerebrospinal fluid (CSF) in neurologic patients have been shown to contain large amount of virus when compared to other body fluids (Hollander and Levy, 1987; Ho et al., 1989).
