Brief Summary
The recent increase in the number of cases of congenital microcephaly observed in Brazil is a reason of great concern. This increase occurred a few months after Zika virus (ZIKV) was introduced in the country, which was associated with reports of pregnant women presenting fever and rash illness during pregnancy. Thus, the hypothesis of a relationship between ZIKV infection and microcephaly became plausible. However, studies on the pathophysiology of maternal ZIKV infection, its consequences for the fetus, and the development of severe encephalopathy are still needed. Knowledge about the natural history of vertical transmission and its association with changes in fetal development in early life is still scarce. Studies on factors which determine the severity and clinical evolution, such as inflammatory response mechanisms, viral evolution, and development of serological tests to identify ZIKV infection, are still needed. The Aedes aegypti is responsible for the transmission of various types of viruses of interest to human health. Currently, it is primarily responsible for the transmission of the dengue, chikungunya, and ZIKV in epidemic proportions. In addition, it is not yet known whether there is an interaction between these viruses and whether the interaction can determine the severity of the disease. The aim of this study is to evaluate the natural history of ZIKV disease in two cohorts( pregnant women and children) starting with pregnant women or newborns or evennursing mothers, identifying risk biomarkers, mapping the anti-viral inflammatory response, evaluating the molecular evolution of the virus,which areimportant to determine the mechanisms of vertical viral infection and verify children neurodevelopment from birth to the end of 3rd year of life.

Outcome Measures
Primary Outcomes (1)
Microcephaly and/or delay in development
Microcephaly at birth or delay in development in Bayley test 3rd edition at 12, 18 and between 24-36 months of age
36 months of age
Secondary Outcomes (2)
ocular injury and cognitive disorder in Bayley Test 3rd edition
36 months of age
Hearing injury and language delay in Bayley Test 3rd edition
36 monthsof age
Study Arms (3)
Child exposed Zika virus proved
child born to mothers with proved zika virus in pregnancy by RT-PCR
Child exposed to zika virus suspected
Child born with symptoms similar to babies proved exposed to zika virus but mothers without symptoms or positive RT-PCR
Normal Child
Normal child from mothers without Zika (IgG and IgM negative)
Interventions
There will be applied Bayley Teste 3rd edition
Eligibility Criteria
The exposure will be confirmed by the positivity in diagnostic tests (PCR or serological tests). Women with and without symptoms will have theirblood sampled for serological tests in the three trimesters of pregnancy and at birth. The pregnant women in the cohort presenting positive results for specifictests (PCR in the acute phase and serological tests later) will be considered exposed to infection whereas pregnant women with negative results will be considered not exposed.
You may qualify if:
- The study population will be composed of pregnant women who present symptoms compatible with ZIKAV infection, with skin rash, arthralgia-associated fever, myalgia, non-purulent conjunctivitis, or headache and asymptomatic pregnant women identified at the same time of possibility of exposure. We will include patients with RT- PCR positive.
- All pregnant women who are in the prenatal follow up at IFF and CSGSF, irrespective of the gestational age, are elegible as a not exposed in the beginning.
- Children born during the outbreak by mothers with confirmed infection, suspected infection and normal pregnancy
You may not qualify if:
- Pregnant women with chromosomal abnormalities detected during fetal life or birth will be excluded.
