YPI = years post infection; WNND = West Nile Neuroinvasive Disease (meningitis, encephalitis, and acute flaccid paralysis); WNF = West Nile Fever; neg = negative/not detected; pos = positive/WNV detected; eqv = equivocal; NA = not available; UNK = unknown. In the event that more than one urine sample and subsequent PCR test was performed in a given year post infection, all test results are listed beside the corresponding year.
