چکیده
A West Nile virus (WNV) outbreak occurred at a commercial waterfowl operation in Wisconsin in 2005. Retrospective analysis of dead and live birds was conducted. WNV was detected by PCR in 84.1% of 88 dead birds; neutralizing antibodies were found in 14 of 30 randomly sampled asymptomatic or recovered birds.

BACKGROUND: West Nile virus (WNV) is a vector-borneagent that is maintained within a bird-mosquito cycle. In humansand equids, infection by this agent is usually asymptomatic, orcharacterized by a mild febrile illness. However, fatal meningoencephalitisor encephalitis may occur.

Twenty percent prevalence of West Nile virus antibody was found in free-ranging medium-sized Wisconsin mammals. No significant differences were noted in antibody prevalence with regard to sex, age, month of collection, or species. Our results suggest a similar route of infection in these mammals.

After the 2001 occurrence of West Nile virus (WNV) in Wisconsin (WI), we collected sera, during 2003-2006, from south-central WI mesopredators. We tested these sera to determine WNV antibody prevalence and geometric mean antibody titer (GMAT). Four-fold higher antibody prevalence and 2-fold higher GMAT in 2003-2004 indicated greater exposure of mesopredators to WNV during the apparent epizootic...
متن کاملEndemic human mosquito-borne disease in Wisconsin residents, 2002-2006.
INTRODUCTION West Nile virus (WNV) and La Crosse virus (LAC) are the primary mosquito-borne arboviruses associated with human disease in Wisconsin. We examined WNV and LAC human illness surveillance data collected during 2002 through 2006. METHODS ELISA-based tests developed by the Centers for Disease Control and Prevention (CDC) were used to detect acute WNV and LAC infection in patient sera...
