RESUMO
INTRODUCTION: Zika virus (ZIKV) infection during pregnancy can result in severe outcomes for both the pregnant woman and the developing fetus. The objective of this study was to investigate the prevalence of Zika virus infection among pregnant women who sought healthcare services at Ahmadu Bello University Teaching Hospital. MATERIALS AND METHODS: Serum samples were collected and analyzed using Enzyme Linked Immunoassay and RT-qPCR methods, while a structured questionnaire was used to gather relevant information about the participants. RESULTS: The results showed that 53 out of the 180 pregnant women tested positive for Anti-Zika IgM antibodies, which represents a 29.4% prevalence rate. Subsequent RT-qPCR analysis found that only 6 out of the 53 positive samples contained Zika virus RNA. Fever and headache were the most commonly reported symptoms related to the infection. CONCLUSION: These findings indicate a potential outbreak of Zika fever in Northern Nigeria emphasizing the importance for pregnant women to take precautions to avoid getting infected.

Throughout the year 2019, Nigeria had sporadic outbreaks of yellow fever (YF), which began in the northern region of the country. Indeed, controlling the bites and population of Aedes mosquitoes and vaccination are the only effective means of preventing YF. Vectorial migration, sylvan-to-urban spillover, immunization failure and, perhaps, genetic modification of YFV could be reasons for the re-emergence of YF at the community, state and national levels. This article offers a critical review of the vector biology, YF vaccine immunodynamics and environmental drivers of YFV infections, with the aim of understanding the interplay of these factors in the re-emergence of YF and risk assessment of living in or travelling to areas where YF is endemic.
