Consistent with the long interval between HIV seroconversion and symptomatic disease, annual HIV-related mortality appears to have peaked in 2004, when 2.2 million deaths occurred. The estimated number of AIDS-related deaths in 2008 is roughly 10% lower than in 2004.The number of children younger than 15 years living with HIV also increased from 1.6 million in 2001 to 2 million in 2007, although the number of newly infected children has been declining since 2003, probably due to the global stabilization of HIV prevalence among women and increasing coverage of programs for PMTCT. In 2007, children accounted for 6% of all people living with HIV, 17% of the people newly infected and 14% of all HIV-related mortality worldwide.
We next evaluated the role of male partners in relation to HIV free survival An outcome which represents the composite risk of infant infection and mortality there by being a more comprehensive measure of impact on infant healthThe results displayed in the left had KM plot for attendance illustrate that approximately 90% of infants of women with male partner attendance, were alive and uninfected through the first year of life the blue dashed curve, as compared to approximately 75% of infants of mothers lacking attendance The red solid curve A proportional difference which was statistically significant The role of the second predictor, previous male hiv testing is depicted in the right hand KM plot These curves show that approximately 85% of infants of women who reported that their male partners had been previously tested for HIV, were alive and uninfected through the first year of life represented by the blue dashed curve as compared to approximately 75% of those infants of mothers who reported that their partners had not been tested the red solid curve Again, representing a proportional difference between the two groups that was statistically significant(NOTE: there were also 13 infant infected < 48 h pp which died but were not used in the analysis and 7 still born infants) (In this population there were 90 events, 50 deaths among which 15 were HIV-infected and 40 HIV-1-infected infants alive through the first 12 months postpartum)
