We surveyed laboratory and surveillance programs on policies, practices, and capacities for testing, confirmation, and reporting (collectively called ascertainment) from 2003 through 2005. We calculated syndrome ascertainment ratios by dividing WNF counts by neuroinvasive disease counts; separately, we performed multilevel modeling. Jurisdictions were more likely to ascertain at least one WNF cases per West Nile neuroinvasive disease case when \u2264 1 testing restrictions existed (odds ratio [OR] = 7.7, 95% confidence interval [CI] = 1.3\u201346.4), when conducting \u2265 4 activities to enhance reporting (OR = 9.3, 95% CI = 1.6\u201354.8), and when \u2265 5.0 staff per million residents were dedicated to arboviral surveillance (OR = 6.4, 95% CI = 1.0\u201340.3). Ascertainment of WNF was less likely among Blacks (OR = 0.56, 95% CI = 0.31\u20130.99) and Hispanics (OR = 0.69, 95% CI = 0.48\u20130.98) than among Whites. Ascertainment was more complete when testing and reporting were enhanced, but differentially incomplete for minorities.<\/jats:p>","DOI":"10.4269\/ajtmh.2010.10-0161","type":"journal-article","created":{"date-parts":[[2010,10,1]],"date-time":"2010-10-01T17:15:08Z","timestamp":1285953308000},"page":"795-802","source":"Crossref","is-referenced-by-count":6,"title":["Differential West Nile Fever Ascertainment in the United States: A Multilevel Analysis"],"prefix":"10.4269","volume":"83","author":[{"given":"Benjamin J.","family":"Silk","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
