Avian Influenza (Bird Flu)
Iceland's Food and Veterinary Authority (MAST) this week announced that highly pathogenic H5N1 avian influenza has been found during the autopsy of a kitten that died, according to a statement translated and posted by Avian Flu Diary, an infectious disease news blog.
Officials said the 10-week-old kitten died on December 22, shortly after two cats from the same litter died but were not tested. Other littermates had left the home before the other cats were sick and remain asymptomatic.
The kittens are from Ísafjörður in the Westfjords region of northwest Iceland, but the one diagnosed as having H5N5 had arrived in Reykjavík, the country's capital.
MAST said the same H5N5 strain had been detected in Iceland's wild birds in September 2024 and in poultry in December 2024. It added that the cats likely contracted the virus from wild birds.
A separate report to the World Organization for Animal Health (WOAH) said the kittens' main clinical signs were lethargy, loss of appetite, cramps, and stiffness.
H5N5 expands geographic range, including Greenland
The most recent quarterly overview of avian flu from the European Centres for Disease Prevention and Control (ECDC) and the European Food Safety Agency (ESFA) said H5N5 viruses continue to expand their geographic and species range, with spillovers to domestic birds reported in Iceland, Norway, and the United Kingdom.
In a new related development, animal health officials in Greenland reported highly pathogenic H5N5 in a northern fulmar, a sea bird, found dead in October in the northwest, according to notification today from WOAH.
China reports mpox clade 1b cluster

Mpox
The China Center for Disease Control and Prevention (China CDC) today announced the country's first confirmed clade 1b mpox cases, which involve a foreigner who had lived in the Democratic Republic of the Congo (DRC) and four close contacts.
In a statement, China CDC said it quickly launched investigations that involve state and provinces, such as Zhejiang, Guangdong, Beijing, and Tianjin.
The four close contacts of the index case-patient mainly had mild symptoms, such as rash. No additional infections have been found among the patients' general contacts. The patients are receiving treatment and are under monitoring.
Twelfth clade 1 appearance outside of Africa
China is the twelfth country outside of Africa to detect clade 1 mpox, which is different from the clade 2 mpox virus spreading globally. The novel clade 1b virus is thought to spread more easily among contacts, including in households. Most cases have been linked to travel to affected African countries.
Outside of Africa, limited secondary transmission has now been reported in the United Kingdom, Germany, and China.
The clade 1b virus is driving outbreak activity in some of Africa's current hot spots, such as the DRC, where household transmission has especially affected children.

Foodborne Disease
Yesterday the Centers for Disease Control and Prevention (CDC) declared its investigation into the Salmonella outbreak linked to cucumbers over after 113 cases and 28 hospitalizations had been identified.
Also, the Food and Drug Administration (FDA) declared its investigation into an outbreak of Escherichia coli O157:H7 infections traced to romaine lettuce over after 88 cases have been reported.
The FDA has not identified the lettuce supplier in that outbreak, according to Food Safety News (FSN).
The FDA also announced an end to another prove into a separate 26-case E coli O157:H7 outbreak without identifying a source of the pathogen, FSN noted.
13 new cases linked to cucumbers
In the outbreak linked to cucumbers, the CDC said 13 new cases and 3 new hospitalizations had been noted since an update on December 19.
Both fresh whole and sliced cucumber from Mexico were recalled in this outbreak. In total 23 states reported cases, and there were no deaths. The CDC found seven clusters of illnesses in this outbreak, including three assisted living facilities, three school districts, and one restaurant.
Illness-onset dates range from October 12 to December 7, 2024. The age of patients varied from less than 1 to 98 years, with a median age of 30, and 60% were women.
The true number of sick people in this outbreak was likely much higher than the number reported, and the outbreak may not have been limited to the states with known illnesses
"The true number of sick people in this outbreak was likely much higher than the number reported, and the outbreak may not have been limited to the states with known illnesses," the CDC said. "This is because many people recover without medical care and are not tested for Salmonella."
CWD shows up in Chippewa County, Wisconsin, for first time in wild deer

Chronic Wasting Disease
Chronic wasting disease (CWD) has been detected in a wild deer in Chippewa County, Wisconsin, for the first time, prompting the renewal of baiting and feeding bans in two counties.
The Wisconsin Department of Natural Resources (DNR) reported the positive case of the fatal neurodegenerative disease yesterday in a 1-year-old buck harvested by a hunter within 10 miles of the Barron and Dunn county borders.
In accordance with state law, Chippewa County will renew its 3-year deer baiting and feeding ban, and Barron County will renew its 2-year baiting and feeding bans. Dunn County already has a 3-year baiting and feeding ban and thus will be unaffected by the finding.
"Baiting or feeding deer encourages them to congregate unnaturally around a shared food source where infected deer can spread CWD through direct contact with healthy deer or indirectly by leaving behind infectious prions in their saliva, blood, feces and urine," the DNR wrote.
First Wisconsin cases identified in 2002
The Wisconsin DNR has been tracking the state's wild white-tailed deer population for CWD since 1999, with the first cases identified in 2002.
Baiting or feeding deer encourages them to congregate unnaturally around a shared food source where infected deer can spread CWD through direct contact with healthy deer or indirectly by leaving behind infectious prions in their saliva, blood, feces and urine.
CWD is caused by infectious misfolded proteins called prions, which spread among cervids such as deer, elk, and moose. The disease isn't known to infect humans, but some experts fear it could cause illness similar to another prion disease: bovine spongiform encephalopathy ("mad cow" disease). The Centers for Disease Control and Prevention warns against eating meat from infected animals.
