This summary aimed to synthesize the protocol guidelines of Pernambuco, the Ministry of Health and the Centers for Disease Control and Prevention which deal with health care related to Zika virus infection during pregnancy and the preliminary procedures for surveillance on microcephaly cases including nutritional care. With the increase of number of cases on this event since August, 2015, it was necessary to reorganize the prenatal care which is offered to pregnant women, including the protocols in order to reduce the chances of a possible contamination of the virus, to detect previously suspected cases as well as perform follow up on confirmed cases. The gaps in the knowledge of this morbidity, it should be noted that the information and recommendations are subject to revision due to possible incorporation of new knowledge and other evidence, as well as the need for adequacy of surveillance actions in new epidemiological scenarios. It is known that cases of nutritional deficiencies...

The implications of Zika Virus exposure in pregnancy for early infant growth remains poorly described. The main goal of this study is to compare the growth, body composition, and feeding modality of infants in the first three months of life by prenatal Zika Virus exposure status. We selected an analytical cohort of 115 infants born without microcephaly, comprising 56 infants with qRT-PCR confirmed exposure to ZIKV during gestation and 59 infants born to women with presumptively no evidence of ZIKV in pregnancy. Infants were evaluated at birth, 1 and 3 months of age in terms of anthropometrics, body composition All the results were adjusted by maternal age, maternal BMI and gestational age. We observe no differences between anthropometric measurements at birth. Mothers in exposed group showed higher BMI. At 1 month and 3 months of age there were differences in mid arm circumference, arm muscle circumference and fat free mass. Weight and length was less in the ZIKV exposed in pregnanc...
The Relationship between Zika Virus and Microcephaly in Infants
2020
Zika virus is a newly emerging disease with little previous information related to its clinical, epidemiological and socioeconomic effects. The complexityof prevention, treatment and care to infected women and neonates, makes Zika one of the major public health problems. We provide an overview of Zika virus infection and the risk of microcephaly in the context of perinatal public health.
Zika Virus Infection and Microcephaly: A Case-Control Study in Brazil
Annals of Global Health
Background: Brazil presented an alarming number of newborns with microcephaly in the years 2015 and 2016. The investigation of the cases raised the suspicion of the association of these cases with maternal infections by the zika virus. Also, in 2015, there was an epidemic of zika virus infection in Brazil, reinforcing this hypothesis. Objective: The objective of this study was to identify factors associated with the diagnosis of microcephaly in newborns, including zika virus infection. Methods: We conducted a case-control study. The cases were defined as children who received clinical and imaging diagnosis of microcephaly, born after October 2015 in Ceará, Brazil, which recorded the highest number of microcephaly cases in Brazil during the outbreak. The cases were identified in medical records of public and private maternity hospitals and in child development stimulation clinics tracked until June 2017. Epidemiological, clinical, and socioeconomic variables were collected, visiting their homes and confirming data from their medical records. Controls were children without microcephaly identified in the vicinity of the residence of each case. Logistic regression models were used to control confounding. Findings: We evaluated 58 cases and 116 controls. The odds of having a baby with microcephaly was 14 times higher among mothers who had zika virus infection (p < 0.001), after multivariate analysis. Arboviruses infections symptoms, as fever (p = 0.220), skin change (p < 0.001), and joint pain (p = 0.002) also demonstrated an association with microcephaly. Conclusions: Maternal infection zika virus was associated with a diagnosis of microcephaly. Our study contributes to the investigation of the epidemiological factors associated with the diagnosis of microcephaly.
The Challenge of Assessing Microcephaly in the Context of the Zika Virus Epidemic
Journal of Tropical Pediatrics, 2017
The present article examines the impact of the current limitations of the microcephaly definition in the context of the Zika virus outbreak. It highlights its dependence on the method used for determining gestational age and other anthropometric parameters, and includes original results of prevalence of microcephaly in four countries from two different continents (Mozambique, Brazil, Guatemala and Colombia). Alternative definitions of microcephaly are proposed to allow the identification of true cases of microcephaly in a more accurate manner.

In 2015, the number of infants born with microcephaly increased in Paraíba, Brazil, after a suspected Zika virus outbreak. We did a retrospective case-control investigation to assess the association of microcephaly and Zika virus. We enrolled cases reported to the national database for microcephaly and born between Aug 1, 2015, and Feb 1, 2016, on the basis of their birth head circumference and total body length. We identified controls from the national birth registry and matched them to cases by location, aiming to enrol a minimum of two controls per case. Mothers of both cases and controls were asked about demographics, exposures, and illnesses and infants were measured at a follow-up visit 1-7 months after birth. We took blood samples from mothers and infants and classified those containing Zika virus IgM and neutralising antibodies as evidence of recent infection. We calculated prevalence of microcephaly and odds ratios (ORs) using a conditional logistic regression model with ma...
Viruses
Background: The Zika virus outbreak has affected pregnant women and their infants. Affected infants develop microcephaly and other congenital malformations referred to as congenital Zika syndrome. The neurological manifestations of congenital Zika syndrome may result in some feeding disorders, including dysphagia, swallowing dysfunction and choking while feeding. The aim of this study was to assess the prevalence of feeding and breastfeeding difficulties in children with congenital Zika syndrome and to estimate the risk of developing feeding disabilities. Methods: We searched PubMed, Google Scholar and Scopus for studies published from 2017 to 2021. From the total of 360 papers, reviews, systematic reviews, meta-analyses and publications in languages other than English were excluded. Therefore, the final sample of our study consisted of 11 articles about the feeding/breastfeeding difficulties of infants and children with congenital Zika syndrome. Results: Infants and children with c...

Introduction: The increase in the number of cases of microcephaly in Brazil and its association with the Zika virus (ZIKV) is a global public health problem. The International Classification of Functioning Disability and Health (ICF) model is a powerful tool and extremely relevant in managing disability. Objective: Describe the functioning profile of children with microcephaly associated with ZIKV in two states of northeastern Brazil. Methods: This is a descriptive cross-sectional study. The sociodemographic characteristics, head circumference, and other clinical data were collected from medical charts, physical examinations, measuring instruments, and interviews with the children and their parents. The Brazilian Portuguese version of the Brief Common ICF Core Set for cerebral palsy (CP) was used. Each ICF category was assigned a qualifier, which ranged from 0 to 4 (no problem, mild problem, moderate problem, severe problem, complete problem). For environmental factors, 0 represents no barrier and 4 represents complete barrier; +0, no facilitator and +4, complete facilitator. Results: A total of 34 children with microcephaly caused by ZIKV were recruited (18 girls and 16 boys) at four rehabilitation facilities in Rio Grande do Norte and Paraíba states, Brazil. The average age of the participants was 21 months, monthly income was ≈USD 300.00, and head circumference z-scores ranged between 0.92 and −5.51. The functioning profile revealed complete disability in most of the body function categories (b). The activity and participation areas (d) were highly impacted, particularly in mobility-related categories. With respect to environmental factors (e), most of the sample reported a complete facilitator for the immediate family, friends, and health services, systems, and policies, as well as a complete barrier to societal attitudes. Conclusion: This is the first study that describes the functioning profile of children with microcephaly associated with ZIKV, using a tool based on the ICF in Brazil. Our findings reinforce the need to maximize health care and access to information, based on the ICF, for multiprofessional teams, administrators, family members, and children.
Characteristics of Dysphagia in Infants with Microcephaly Caused by Congenital Zika Virus Infection, Brazil, 2015 , 2017
We summarize the characteristics of dysphagia in 9 infants in Brazil with microcephaly caused by congenital Zika virus infection. The Schedule for Oral Motor Assessment, fiberop-tic endoscopic evaluation of swallowing, and the videofluo-roscopic swallowing study were used as noninstrumental and instrumental assessments. All infants had a degree of neurologic damage and showed abnormalities in the oral phase. Of the 9 infants, 8 lacked oral and upper respiratory tract sensitivity, leading to delays in initiation of the pha-ryngeal phase of swallowing. Those delays, combined with marked oral dysfunction, increased the risk for aspiration of food, particularly liquid foods. Dysphagia resulting from congenital Zika virus syndrome microcephaly can develop in infants >3 months of age and is severe.
