RESUMO
Beginning in 2015, Brazil witnessed the births of thousands of children with neurological abnormalities linked to the Zika virus. Drawing on ethnographic fieldwork conducted between 2016 and 2018 with parents of children with congenital Zika syndrome in Salvador da Bahia, this article attends to how one of Brazil's most overused obstetric technologies-cesarean section-was mobilized to mitigate the uncertainties of Zika's reproductive consequences. I argue that during the epidemic, C-section constituted a form of what I call interventive care, in which others interceded on behalf of pregnant women to secure surgical delivery. In dialogue with scholarship problematizing autonomy in reproductive decision making, I show how my Bahian interlocutors understood such intercessions, and the C-sections themselves, as forms of appropriate, concerned care. I suggest, furthermore, that interventive care highlights the ways in which reproductive decisions are distributed among people rather than autonomous, particularly in contexts of heightened uncertainty.

OBJECTIVES: We assessed sociodemographic and health care factors of mothers and newborns during a 2015-2016 outbreak of microcephaly in Recife, Brazil, and we analyzed the spatial distribution and incidence risk of newborns with microcephaly in relation to socio-environmental indicators. METHODS: We collected data from August 2015 through May 2016 from Brazil's Live Birth Information System and Bulletin of Microcephaly Notification, and we geocoded the data by maternal residence. We constructed thematic maps of districts, according to socio-environmental and vector indicators. We identified spatial aggregates of newborns with microcephaly by using the Bernoulli model. We performed logistic regression analyses to compare the incidence risk of microcephaly within socio-environmental indicator groups. RESULTS: We geocoded 17 990 of 19 554 (92.0%) live births in Recife, of which 202 (1.1%) newborns were classified as having microcephaly, based on a head circumference of ≥2 standard deviations below the mean. Larger proportions of newborns with microcephaly (compared with newborns without microcephaly) were born to mothers who delivered in a public hospital, did not attend college, were aged ≤19, or were black or mixed race. A higher risk of microcephaly (incidence rate ratio [IRR] = 3.90; 95% confidence interval [CI], 1.88-8.06) occurred in districts with the lowest (vs highest) Municipal Human Development Index (ie, an index that assesses longevity, education, and income). The risk of microcephaly was significantly higher where rates of larvae density (IRR = 2.31; 95% CI, 1.19-4.50) and larvae detection (IRR = 2.04; 95% CI, 1.05-4.00) were higher and rates of sewage system (IRR = 2.20; 95% CI, 1.16-4.18) and garbage collection (IRR = 1.96; 95% CI, 0.99-3.88) were lower. Newborns with microcephaly lived predominantly in the poorest areas and in a high-risk cluster (relative risk = 1.89, P = .01) in the north. CONCLUSIONS: The disproportionate incidence of microcephaly in newborns in poor areas of Recife reinforces the need for government and public health authorities to formulate policies that promote social equity and support for families and their children with microcephaly.

French Polynesia and the French Territories of the Americas (FTAs) have experienced outbreaks of Zika virus (ZIKV) infection. These territories used similar sentinel syndromic surveillance to follow the epidemics. However, the surveillance system only takes into account consulting patients diagnosed with ZIKV disease, while non-consulting cases, as well as asymptomatic cases, are not taken into account. In the French territories under study, the ratio of consulting to non-consulting patients was found to likely be as low as 1/3 to 1/4, and rough estimates of the ZIKV asymptomatic infections indicated a lower rate than previously reported (i.e., not more than half).

BACKGROUND: Zika virus (ZIKV) is transmitted by Aedes mosquitos and can result in severe congenital and adult neurologic abnormalities. ZIKV has rapidly spread northward through Central America and the Caribbean and autochthonous cases have been identified in the continental United States. High rates of ZIKA RNA positivity were detected in blood donors during previous epidemics. ZIKV transmission by transfused blood from healthy donor components has been a growing concern. STUDY DESIGN AND METHODS: Individual-donation aliquots of plasma from volunteer blood donors were tested individually with an investigational Procleix ZIKV assay. Initially reactive samples were tested for ZIKV RNA in plasma and red blood cells (RBCs) and for ZIKV-specific antibodies in serum. A confirmed positive classification required confirmation of RNA and/or detection of ZIKV antibodies in index and/or follow-up samples. RESULTS: Between September 19 and November 30, 2016, a total of 466,834 donations were screened for ZIKV RNA. Five donors (one in approx. 93,000) were reactive for ZIKV RNA by both the Procleix ZIKV assay and supplemental testing. The donations were collected outside areas considered as having active transmission, and all five donors had travel exposures. A lookback case demonstrated no infection despite transfusion of a Zika IgG-positive platelet (PLT) component with probable low levels of ZIKV RNA. CONCLUSIONS: This report describes the first ZIKV-positive donors detected outside areas with active transmission. These donors most likely represent travel-acquired "tail-end infections" with prolonged RBC-associated ZIKV RNA. The lack of transmission to the recipient of an apheresis PLT may suggest that these units are not infectious.

A 6-day-old female baby with known diagnosis of congenital Zika infection was referred for ophthalmologic examination. The mother (37 years old) was referred for a pruritic rash, conjunctival hyperemia, and malaise at 12 weeks of gestation while still living in Venezuela. Upon arrival to Miami, Zika virus (ZIKV) exposure was confirmed during prenatal screening. At birth, due to the known exposure, a complete congenital ZIKV workup was performed, including brain ultrasound and MRI, which disclosed calcifications in the frontal lobe. Fundus examination revealed a hypopigmented retinal lesion in the left eye that was documented with retinal imaging. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:952-955.].
