HIV testing is of particular importance during pregnancy because antiretroviral drugs can be administered in an effort to prevent transmission of the virus to the fetus. Anderson and Sansom (2007) used data from the Behavioral Risk Factor Surveillance System (an ongoing national telephone survey) to determine whether pregnant women were indeed getting tested for HIV at a higher rate than nonpregnant women. Results of the survey indicated that in the general population of women aged 18 to 44, 15.4% had been tested for HIV within the past year. Of the 4855 pregnant women surveyed, 2627 had been tested for HIV within the past year.
