The Global Polio Laboratory Network (GPLN) continues to play an essential role in global polio eradication, and periodic efforts to quantify its overall value provide important information that helps to motivate financial support for GPLN laboratories. Assessing the value of the GPLN is of utmost importance at the current stage of the GPEI, as the partners discuss the strategies to maintain polio laboratory functions pre- and post-certification of wild poliovirus eradication and global containment of live polioviruses. This GPLN survey aims to collect data on activities and costs of all of the GPLN laboratories to support an overall synthesis. The objectives of this survey include 1) to update estimates of the total costs of the GPLN estimated using a similar survey in 2003 (published in de Gourville EM, Sangrujee N, Duintjer Tebbens RJ, Pallansch MA, Thompson KM. Global Surveillance and the value of information: The case of the global polio laboratory network. Risk Anal. 2006;26:1557-69), 2) to better understand the different cost components, including related to environmental poliovirus surveillance, 3) to better understand the extent to which the GPLN contributes to surveillance of other diseases.  Assuming readily available data, the survey should take approximately 60 minutes.  The survey includes questions about acute flaccid paralysis (AFP) surveillance (i.e., stool samples from AFP cases and contacts) and environmental surveillance (i.e., sewage samples). 
Please note:
·       we pre-filled some answers based on data collected by the GPLN annual reports for 2016 as of March 15, 2017, and we ask that you please check the pre-filled answers carefully and correct the information as appropriate
·       please do not leave any answers blank, because we cannot interpret these correctly, so please enter “0” for zero, “unknown” for unknown, “not applicable” for not applicable, or “data not available” or other appropriate text (if you find any question too difficult to answer, please do not quit the entire question or survey, but instead reply with “unable to answer” and please add any detail that can help us understand the reason)
Thank you very much for your time and effort to respond to the survey.  We look forward to hearing from you.  We will share the results with all polio laboratory directors for dissemination once it becomes available.
