Under ideal circumstances. the probability that a testing sequence will be falsely positive or negative in a population with a low rate of infection is 1 in 100.000. Most importantly. this amendment could reduce the human suffering associated with the birth of an HIVinfected infant. According to a model developed by California physician Larimore Cummins. based on CDC assumptions and PHS data. infant mortality could be substantially reduced by testing women of childbearing age in community and migrant health centers. The model assumes: Three million six hundred thousand women of childbearing age visit community and migrant health centers over a 1year period. Women in this age group give birth to approximately 2 infants (the national average) during their childbearing years but that the clinic is only able to intervene in 1 of those two births.
