The World Health Organization has published a 14-page report outlining the WHO-led global response to the Zika Virus, and the emerging funding (or lack thereof) that they've received to date.
The report begins with brief sections on Zika's background and on last February's Strategic Response Framework and Operations Plan, which is summarized in the graphic below.
It then provides an agency by agency list of funding requests, the funding actually received, and the resultant gap. At this point these funding gaps run (depending on which agency) from about 80% to 99%.
The full report is available HERE.
