[90 percent cases of HIV transmission are due to perinatal contagion or breastfeeding. One million children were HIV positive in 1977] El 90 por ciento de casos por contagio perinatal o lactancia. Un millon de niños/as portan VIH en 1977.
RedAda. 1997 Dec; (26):22-24.A million children under 15 years of age will have contracted HIV worldwide by 1997, while in 1996, of the one and a half million people who died of this disease, 350,000 were under 15, according to UNAID numbers released on the occasion of the world AIDS campaign (December 1), whose theme this year is "Children in a World with AIDS." Approximately 90 percent of children with HIV were infected by their mothers, during pregnancy or childbirth or through mother's milk, according to the UN organization. (excerpt)
AIDS. 1992 Dec; 6(12):1505-13.HIV/AIDS specialists have developed and applied 3 different scenarios to a comprehensive decision analysis model to estimate mortality rates for children of mothers infected with HIV during pregnancy and for children of mothers who were not infected with HIV during delivery. Scenario I represents Central Africa where HIV prevalence and incidence are high. Some scenario I assumptions are HIV prevalence in pregnant women of 30% and proportion of initially uninfected women who become infected after delivery during lactation (d) of 6%. Scenario II is a population where HIV epidemic is rather recent (e.g., some parts of Asia). Its assumptions are HIV prevalence of 5%, and s is 2%. Scenario III symbolizes high-risk populations in North America and Western Europe (HIV prevalence and s = 1%). The scenarios also consider child mortality rates and relative risks (RRs) of mortality of breast fed children and those who were not breast fed. Universal breast feeding would effect equal or higher mortality than non-breast feeding, when the RR of mortality is no more than 1.5 and HIV prevalence/incidence is high (high prevalence = > 10% and high incidence = > 5%). In developing countries, where the RR of mortality is high if children are not breast fed (RR > 3), breast fed children have almost always lower child mortality than those who are not breast fed, regardless of HIV infection status. The decision to breast feed when the HIV status is known depends greatly on the degree of an additional mortality risk if an infant is not breast fed. The model substantiates WHO and CDC recommendations: HIV-positive women in the UK and the US should not breast feed, while those in developing countries with high RR of child mortality should breast feed. Additional research would define the range of HIV transmission rates from breast feeding and increase specific assessments of RRs for various parts of the world.
