Avian flu strikes more poultry in 3 states; first wild bird detections in WI
Three already-affected states—Maine, South Dakota, and Wyoming—reported more highly pathogenic avian flu outbreaks in poultry flocks, and Wisconsin reported its first detections in wild birds, according to updates from federal and state agriculture officials.
South Dakota's latest outbreak occurred at a commercial turkey farm in Brule County housing 55,219 birds, the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) said on its update page. Brule County is in south central South Dakota, and the latest outbreak is state's 21st.
The outbreaks in Maine and Wyoming both involve backyard mixed-species flocks. Maine's event, its 11th, occurred in Lincoln County on the state's Atlantic coast. Wyoming's outbreak marks its second and struck a location in the far northwest.
And the Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP) yesterday reported that highly pathogenic avian flu, based on preliminary positives from testing, has been found in wild birds in five counties: Dane, Columbia, Grant, Milwaukee, and Polk. Earlier this month, Wisconsin reported its first outbreak in poultry, on a large layer farm in Jefferson County.
The outbreaks and detections are part of expanding Eurasian H5N1 activity that began in January and has now spread to wild birds or poultry in 31 states.

Flu activity shifting to northern corners of US
Flu levels in the Northeast and Northwest rose last week, and although activity is still highest in central and southeast regions, markers there showed signs of decline, the US Centers for Disease Control and Prevention (CDC) said today in its latest weekly update.
The percentage of outpatient visits for flulike illness held steady, at 1.8%, and is still below baseline. At public health labs, all respiratory samples that were positive for flu were influenza A, and, of subtyped influenza A samples, all were H3N2.
In another measure of clinic visits for flu, New Mexico reported high activity. Four states reported moderate activity: Kansas, Oklahoma, New Hampshire, and Utah.
Hospitalizations rose for the eighth straight week. The cumulative hospitalization rate for flu this season, however, is still below the average of the past four prepandemic flu seasons. One more pediatric flu death was reported, raising the season's total to 14. The death occurred during the week ending Mar 5 and involved the H3N2 strain.
