An overview of financial sources being utilized to support Zika Virus published research.

BACKGROUND: Since 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.

OBJECTIVES: To 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.

METHODS: A 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.

FINDINGS: 268 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%).

INTERPRETATION: The evidence suggests international efforts to fund ZIKV research and a need to foster collaborative and synchronized priority setting for resource allocation.
