CDC reports 17 more unexplained hepatitis cases in kids

The US Centers for Disease Control and Prevention (CDC) said it has received 17 more reports of unexplained pediatric hepatitis cases that are under investigation, raising the nation's total to 355.

The number of states reporting cases remained the same, at 42.

Similar cases have been reported in several countries, and so far the strongest lead from epidemiologic investigations is a possible role for adenovirus. Scientists, however, are examining several other contributors, which they say might include prior COVID-19 infection, atypical immune response, or exposure to environmental or toxic triggers.

Globally, more than 1,000 cases have been reported, and the World Health Organization recently announced new efforts to gauge prepandemic levels of unexplained hepatitis and liver transplants in children.

More avian flu confirmed in US poultry and wild birds

Sporadic highly pathogenic avian flu outbreaks continue to strike US poultry, as federal officials report three more outbreaks, including one at a commercial farm in Utah.

In its latest update, the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) said the outbreak in Utah occurred in Sanpete County, located in the central part of the state, just south of Provo. The facility houses 25,900 birds. The event marks the second recent outbreak at a turkey producer in the county.

Also, officials reported two outbreaks in backyard birds, one in Oregon's Deschutes County and the other in Washington's Snohomish County.

Since the outbreaks in poultry began in early February, the H5N1 outbreaks—which involve the Eurasian strain circulating in several parts of the world—have led to the loss of 40.1 million birds across 37 states.

In related developments, APHIS this week reported 64 more detections in wild birds, raising the total this year to 1,890. The notifications came from several parts of the country and included several vultures, along with gulls, waterfowl, raptors, and even a few ravens.
