In the wake of a recent H5 avian flu detection in wastewater on Oahu, the Hawaii Department of Agriculture (HDOA) on November 15 announced that state and federal tests have confirmed the virus in ducks and geese that died on a backyard farm.

Bird Flu Map Shows States Where H5N1 Has Spread
Hawaii could become the eighth U.S. state to see human cases of bird flu, after the state's Department of Health issued a warning on Sunday to members of the public who attended a pet fair. The Centers for Disease Control and Prevention (CDC) has so far confirmed 52 human cases of bird flu—otherwise known as avian influenza H5N1—during this year's outbreak: 26 in California, 11 in Washington, 10 in Colorado, two in Michigan and one each in Missouri, Oregon and Texas. This figure has grown from 46 cases last week, with Oregon reporting its first case on Friday, showing the outbreak is spreading. (Willmoth, 11/18)

Months after filing for bankruptcy, VBI Vaccines is taking the next step in shuttering operations with the voluntarily withdrawal of its hepatitis B vaccine, PreHevbrio.
