OBJECTIVE

To determine the incidence of HIV infection in pregnant women treated at the National Maternal and Perinatal Institute (Lima, Peru), between 2007-2016.

MATERIAL AND METHODS

Observational, descriptive and retrospective study. The results of the diagnostic tests of HIV in pregnant women were reviewed, carried out according to current national regulations, which includes the screening tests (immunochromatography and / or ELISA), which in case of being reactive were corroborated by confirmatory tests (indirect immunofluorescence and Western Blot). The incidence of HIV was measured according to the annual trend, and the Pearson correlation and χ2 test were applied to compare the characteristics of the incidence profile.

RESULTS

113,258 pregnant women were screened, obtaining an incidence of 2.91 per thousand pregnant women, the annual trend was erratic, except between 2014 and 2016 where there was a tendency to decrease. Only 22.73% of the couples of the pregnant women were screened, the seroconcordance was 10.3%, and the serodiscordance was 12.42%. The frequency of seroconcordance correlated directly with the percentage of sifted couples and inversely with the frequency of HIV (p <0.05). The condition of coexistence or single mother was associated more frequently with the lack of screening of the couple (p <0.001).

CONCLUSIONS

The confirmed incidence of HIV was erratic (2007-2016). Strategies should be elaborated to increase the screening in the pairs of the infected pregnant women, taking into account the high frequency of the instability of said union.
