“…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).…”

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.

“…In serologic surveys conducted in Nigeria, Macnamara et al (10) noted that sera capable of neutralizing ZIKV in mouse protection experiments were also strongly associated with neutralization of DENV and YFV, suggesting serologic overlap or cross-reactivity. In fact, DENV was considered in the differential for identification of the causative agent of the 2007 Yap Islands ZIKV outbreak due in part to falsepositive rapid DENV IgM test results, despite a clinical syndrome that was not entirely consistent with dengue (22,23,64). The manufacturer of this DENV IgM assay was not disclosed.…”

“…However, this notion changed in 2007 when the pandemic befell Micronesia and Island in the State of Yap with over 5000 infections in a population of 6700 (Duffy et al, 2009). Another outbreak of the infectious virus was reported in French Polynesia in 2013 and 2014 (Hancock et al, 2014). Other related cases also occurred in 2014 in Pacific Islands like in Cook Islands, Samoa, and American Samoa (Hancock et al, 2014; Tappe et al, 2015; Magauran et al, 2016).…”

The increasing trend in the spreading virus indicated how this dangerous ZIKV infection was able to cause inevitable trouble that the world was likely headed to if the problem was not controlled in time.…”

Zika Virus Infection during Pregnancy and Congenital Abnormalities

et al. 2017

The presence of the Zika virus (ZIKV) infection has gone ahead to be a threat to people based on its adverse impacts. More specifically, the pregnant women have been discouraged from traveling to the areas affected by the ZIKV because of the likelihood of the virus causing congenital abnormalities especially the microcephaly. The pregnant women probably attracted the virus during their first trimester while visiting ZIKV affected territories. Although the ZIKV infected cases have reduced in some parts of countries, the global risk assessment has not been changed. The virus continues to spread geographically to areas where competent vectors are present. At present, there is still no treatment of ZIKV related illness, especially microcephaly.
