Biological and historical overview of Zika virus.

ABSTRACT: The recent outbreak of the Zika virus attracts worldwide attention probably because the most recently affected country (Brazil) will host the 2016 Olympic Game. Zika virus infected cases are now spreading to many other countries and its infection might be linked to some severe medical sequelae. Since its first isolation from the infected monkey in 1947 in Uganda, only a few studies had been taken until recent outbreak. According to the history of referenced publications, there is a 19-year gap from 1989 to 2007. This might be because only mild diseases were diagnosed from Zika virus infected populations. Obviously, the recent reports that Zika virus infection is probably associated with microcephaly of the neonates makes us reevaluate the medical significance of the viral pathogen. It can be transmitted sexually or by mosquito biting. Sexual transmission of the Zika virus distinguishes it from other members of the Genus Flavivirus. Detailed information of the Zika virus is needed through a thorough investigation covering basic, epidemical, subclinical and clinical studies. Here, we reviewed the published information of Zika virus.

Project description:BackgroundSince its initial detection in Brazil in 2015, Zika Virus (ZIKV) has spread rapidly throughout most of the Caribbean and South, Central and North America. An upsurge in congenital syndrome associated with ZIKV and Guillain-Barre Syndrome (GBS) has been associated with the increase in ZIKV. This amplification in numbers led to the need for funded research initiatives focusing on various countries globally and on specific experimental types.ObjectivesTo determine the financial institutions involved in the production of primary research into the ZIKV epidemic. This research also intends to draw attention to the investigative areas that are dominating, experimental types being conducted and the geographical areas that are producing the bulk of the research utilizing available funds.MethodsA cross sectional search of published primary research was conducted using Pan American Health Organization (PAHO) Zika platform and PubMed between January 2007 and October 2016. Titles, abstract and full articles were assed and one researcher extracted data. Information was crossed checked by a second researcher to ensure accuracy.Findings268 articles were included and investigations occurred across 48 countries with Brazil and USA dominating the research. Applied Research and Laboratory based studies were most frequently utilized. 38.1% of articles did not report financial sources. Public institutions were the major known contributors. Other financiers included private, non-profits and mixed funders exclusive of public sources. 156 individual financial bodies assisted with National Institute of Health being most frequently mentioned followed by The National Council for Scientific and Technological Development (CNPq) and the Institut Pasteur. Virus, vectors and reservoirs was most frequently used (99/268, 36.9%) followed by clinical management (70/268, 26.1%) and epidemiology (46/268, 17.2%).InterpretationThe evidence suggests international efforts to fund ZIKV research and a need to foster collaborative and synchronized priority setting for resource allocation.
