The observation of congenital malformations associated with vertical transmission (mother-fetus) of Zika Virus (ZIKV) such as microcephaly, made ZIKV a global threat to health, especially for child development. In this scenario, the Instituto Nacional de Salud (INS) - Colombia, established the collection of biological samples of pregnant women with ZIKV infection collected in the context of intensified surveillance during the 2015-16 Zika epidemic in Colombia. The samples were collected in three cities in Colombia that presented the highest number of cases: Cali, Barranquilla, and Cúcuta. From this surveillance, 461 pregnant women were included. The database and its samples rest in the COMMAFEZ collection of the INS.
La observación de malformaciones congénitas asociadas a la transmisión vertical (madre-feto) del virus del Zika (ZIKV) como la microcefalia, convirtió al ZIKV en una amenaza mundial para la salud, en especial para el desarrollo infantil. En este escenario, el Instituto Nacional de Salud – Colombia, estableció la colección de muestras biológicas de mujeres embarazadas con infección por ZIKV recolectadas en el marco de la vigilancia intensificada durante la epidemia del Zika en Colombia en el periodo 2015-2016. Las muestras fueron colectadas en tres ciudades de Colombia que presentaron el mayor número de casos: Cali, Barranquilla y Cúcuta. A partir de ésta vigilancia se incluyeron 461 gestantes. La base de datos y sus muestras reposan en la colección COMMAFEZ del Instituto Nacional de Salud.

Данные проекта
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.

| Описание плана выполнения исследований | Main goal To assess the relationship between Zika virus infection during pregnancy and adverse outcomes in pregnancy, childbirth and in the infant until the first two years of life. The methodology was divided into three phases that consisted of: 1) Case analysis: surveillance of microcephaly and congenital defects (CD) of the central nervous system (CNS), 2) Surveillance of pregnant women with Zika and 3) Follow-up of infants with prenatal exposure to Zika virus. |

Методы сбора
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.

| Контроль качества | The samples were taken by trained biomedical personnel throughout the process, complying with the biosafety standards for the handling of the samples and following the INS Sample Collection instructions (INT-R03.318-006), which was authorized in the framework of the epidemiological surveillance of the Zika virus developed by the INS and the sample management protocol in the epidemiological surveillance mission studies carried out by the Technical Directorate of Surveillance and Risk Analysis. Also, the guidelines of the Manual for obtaining and sending samples for analysis of events of interest in public health carried out by the INS in 2011, were followed.

Описание этапа методики:
- 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.
