“…Approximately, 30,000 humans (about 11 % of the total French Polynesian population) developed ZIKV infection [18][19][20][21]. This French Polynesian virus was closely related to the virus isolated in Cambodia in 2010 [10]. Subsequently, in 2014, ZIKV was also detected in Easter Island (Chile), the Cook Islands and New Caledonia [22].…”

“…Phylogenetic analyses of ZIKV suggest two important lineages, Asian and African, originating from a single ancestor, most likely in Uganda [7]. The possible vectors of Aedes species include Aedes polynesiensis and Aedes aegypti, identified in French Polynesia, and Aedes hesilli, identified in Yap [8,10,11]. Aedes albopictus and A. aegypti exist in many states of America, including various parts of the south-central and south-eastern USA and Hawaii [5,8].…”

“…Major outbreaks of Zika virus (ZIKV), a mosquito‐borne neurotropic flavivirus, have been reported in the island of Yap (2007), French Polynesia (2013–2014), and several Latin‐American countries (2014) 1, 2, 3, 4. During the ZIKV outbreak in French Polynesia, a profound 20‐fold increase in the number of Guillain–Barré syndrome (GBS) was reported 5.…”

ObjectivePrevious studies have associated Guillain–Barré syndrome (GBS) with Zika virus (ZIKV) outbreaks in South America and Oceania. In Asia, ZIKV is known to circulate widely, but the association with Guillain–Barré syndrome is unclear. We investigated whether endemic ZIKV infection is associated with the development of GBS.MethodsA prospective study was conducted from 2011 to 2015 in Bangladesh. A total of 418 patients and 418 healthy family controls were included in the study. Patients were diagnosed with GBS prior to inclusion according to established criteria. Detailed information on the epidemiology, clinical presentation, electrophysiology, diagnosis, disease severity, and clinical course were obtained during a follow‐up of 1 year using a predefined protocol.Results ZIKV‐neutralizing antibodies were detected in our study from 2013 onwards. The prevalence of ZIKV‐neutralizing antibodies was not significantly higher in patients with GBS compared to healthy controls (OR 2.23, P = 0.14, 95% CI 0.77–6.53). Serological evidence for prior ZIKV infection in patients with GBS was associated with more frequent cranial, sensory, and autonomic nerve involvement compared to GBS patients with Campylobacter jejuni, the predominant preceding infection in GBS worldwide. Nerve‐conduction studies revealed that ZIKV antibodies were associated with a demyelinating subtype of GBS, while C. jejuni infections were related to an axonal subtype.InterpretationNo significant association was found between ZIKV infection and GBS in Bangladesh, but GBS following ZIKV infection was characterized by a distinct clinical and electrophysiological subtype compared to C. jejuni infection. These findings indicate that ZIKV may precede a specific GBS subtype but the risk is low.

“…The first large outbreak of Zika disease in humans occurred on the Pacific island of Yap in the Federated States of Micronesia in 2007 (Lanciotti et al, 2008;Duffy et al, 2009). ZIKV was then identified from Suriname (Enfissi et al, 2016b) in South America, and on other Pacific Islands including French Polynesia (Berthet et al, 2014;Cao-Lormeau et al, 2014;Hancock et al, 2014), Easter Island of Chile (Tognarelli et al, 2015), the Cook Islands (Roth et al, 2014), and New Caledonia (Roth et al, 2014;Dupont-Rouzeyrol et al, 2015). Imported cases were also identified in countries of the Americas and Europe (Foy et al, 2011;Waehre et al, 2014;Zammarchi et al, 2015;Kindhauser et al, 2016).…”

Phylogenetic analysis revealed the central roles of two African countries in the evolution and worldwide spread of Zika virus

Recent outbreaks of Zika virus (ZIKV) infections inOceania's islands and the Americas were characterized by high numbers of cases and the spread of the virus to new areas. To better understand the origin of ZIKV, its epidemic history was reviewed. Although the available records and information are limited, two major genetic lineages of ZIKV were identified in previous studies. However, in this study, three lineages were identified based on a phylogenetic analysis of all virus sequences from GenBank, including those of the envelope protein (E) and non-structural protein 5 (NS5) coding regions. The spatial and temporal distributions of the three identified ZIKV lineages and the recombination events and mechanisms underlying their divergence and evolution were further elaborated. The potential migration pathway of ZIKV was also characterized. Our findings revealed the central roles of two African countries, Senegal and Cote d'Ivoire, in ZIKV evolution and genotypic divergence. Furthermore, our results suggested that the outbreaks in Asia and the Pacific islands originated from Africa. The results provide insights into the geographic origins of ZIKV outbreaks and the spread of the virus, and also contribute to a better understanding of ZIKV evolution, which is important for the prevention and control of ZIKV infections.
