Prevalence of Arbovirus Infections among Pregnant Women at a Maternity Hospital School
Objective: Survey the prevalence of arbovirus infections among pregnant women provided with care at a maternity hospital school in Recife, Pernambuco, Brazil.
Method: Descriptive, cross-sectional, retrospective, and quantitative study, carried out with data collected from the notification forms filled in during obstetric screening between August 2015 and July 2016.
Results: Positive serology was found for arboviruses in 40.2% of the 103 suspected cases. Serology was not performed or it showed inconclusive results in 59.8% of the cases. Dengue fever occurred in 44% of the cases, chikungunya in 34%, and zika fever in 22%. Infections were more frequent among pregnant women over 20 years old, with low income and low schooling levels, living in Recife (48.5%) and Olinda, Pernambuco, Brazil (24.3%). The most frequently mentioned symptoms were arthralgia (94%), exanthema (82%), and fever (78%). Infections occurred within the first trimester of pregnancy (54.5%), 63.3% of the pregnant women had to be hospitalized, and 45.4% of them did not undergo morphological ultrasonography. Most babies were born full-term and they had adequate weight. The prevalence of microcephaly was 9.7% when considering cases of arbovirose and 62.5% when considering specific cases of zika fever.
Conclusion: The prevalence and repercussions of arboviruses justify the consolidation of actions to fight Aedes aegypti, as well as the effective deployment of clinical protocols and recommendations aimed at the mother and child care.
