The MOH also reported the death of a 75-year-old Saudi man from Taif who had an underlying medical condition and was not likewise a healthcare worker.

China and France report ongoing high-path avian flu outbreaks

France and China are responding to outbreaks of highly pathogenic avian flu, according to reports their agricultural officials filed with the World Organization for Animal Health (OIE) yesterday and today.

On Mar 6, China detected an H5N6 outbreak on a farm housing 34,233 birds in Jiangxi province, according to an OIE report today. The virus sickened 34,233 birds, causing 14,705 deaths and prompting destruction of the rest to prevent the spread of infection.

On Mar 4, French officials discovered the H5N9 virus in two holdings of water birds located in the commune of Arsagues in France's southwestern Landes region. The 14,370 birds on the two farms are scheduled to be culled. The most recent previous H5N9 outbreak in France was a month ago.

Officials in both countries are implementing disease control procedures, including movement control and disinfection of affected facilities.

Wisconsin notes more bloodstream infections in Elizabethkingia outbreak

Wisconsin health officials have identified 4 more bloodstream infections caused by the bacterium Elizabethkingia anophelis, bringing the state's outbreak total to 48, the Wisconsin Department of Health Services (WDHS) said yesterday. Eighteen deaths have been reported since the beginning of the outbreak.

The source of the outbreak is currently unknown, the WDHS said, and most patients are over the age of 65. All patients have a history of an underlying serious illness, though the agency did not specify how many patients contracted the infection in healthcare settings.

Cases occurred between Nov 1, 2015, and Mar 9, 2016, and have involved residents of Columbia, Dane, Dodge, Fond du Lac, Jefferson, Milwaukee, Ozaukee, Racine, Sauk, Sheboygan, Washington, and Waukesha counties.

E anophelis is an opportunistic pathogen that typically affects people how are immune-compromised or have serious underlying medical conditions. The WDHS has notified healthcare providers and laboratories about the outbreak and has provided treatment guidance to Wisconsin clinicians. Untreated infections are associated with a high mortality rate, the WDHS said.

Though E anophelis is a multidrug-resistant bacterium, the WDHS said that isolates from outbreak patients reveal it is susceptible to fluoroquinolones, rifampin, and trimethoprim/sufamethoxazole. Testing performed by the Centers for Disease Control and Prevention on nine Wisconsin isolates found similar results, with the addition of detecting susceptibility to minocycline.

Combination treatment is more effective than monotherapy in treating bloodstream infections caused by E anophelis, the WDHS said.
