Datos del proyecto

During September 2015 to December 2016, more than 100,000 cases of ZIKV infection were notified to SIVIGILA, of which, more than 18,000 were pregnant women. Due to the greater impact of this agent when the infection occurs during pregnancy, the INS and the CDC implemented the project "Intensified Surveillance of Pregnant Women with Zika (VEZ)" in three cities of Colombia that presented the highest number of cases: Cali, Barranquilla, and Cúcuta. Within the framework of this project, more than 1200 pregnant women and her babies were included for follow-up during pregnancy, childbirth and until the first 2 years of their life.

Métodos de muestreo

Biological material was collected from pregnant women with suspected ZIKV infection who attended for medical consultation at Health Services Provider Institutions in the cities of Cali, Barranquilla, and Cúcuta. 2833 samples were cryopreserved in saline solution at -80°C, including umbilical cord 36%, placenta 35%, cord blood 11%, serum 10%, urine 5%, ovular membranes 1%, amniotic fluid 1% and other tissues 1%. 1762 samples of placental, cord and fetal tissues were Formalin-Fixed and Paraffin-Embedded (FFPE) and 3063 slides with tissue sections were processed for histopathological analysis.

Descripción de la metodología paso a paso:

1. 1) Identification of symptomatic pregnant women: Pregnant women with suspected infection by ZIKV were notified to the public health surveillance system of INS SIVIGILA. Once identified, they were invited to participate in the follow-up of their pregnancy and their children until they were two years old. 2) Once the informed consent was signed, samples were taken of the placenta, umbilical cord, urine, amniotic fluid, and umbilical cord blood during delivery, in order to subsequently demonstrate the presence of Zika virus in any of these. 3) Placental Processing Surveillance program for pregnant women with Zika - sent in neutral buffered formalin. 4) Shipment of placental paraffin blocks in the framework of ZIKA research (VEZ program). 5) Histopathological analysis. 6) Data management: The information associated with the tissues rests physically in the file of the Maternal and Perinatal Health (INS) group and a magnetic medium database. Data collected from the clinical history and epidemiological notification form of SIVIGILA.
