U.K. detects first human case of 'distinct' form of swine flu

Dec 04, 2023

Officials are racing to track the contacts of the United Kingdom's first human case of a "distinct" form of swine flu.

On Monday, the U.K. Health Security Agency (UKHSA) announced it had detected a single confirmed human case of influenza A(H1N2)v as part of routine national flu surveillance.

There have been dozens of human cases of that strain reported globally since 2005, but none of them are genetically related to the recently identified case, officials said.

"Based on early information, the infection detected in the U.K. is a distinct clade (1b.1.1), which is different from recent human cases of influenza A(H1N2) elsewhere in the world but is similar to viruses in U.K. swine," reads the UKHSA's statement.

Officials said the individual experienced a mild illness and fully recovered, but the source of their infection isn't yet known.
"We are working rapidly to trace close contacts and reduce any potential spread," Meera Chand, the UKHSA's incident director, said in a statement. "In accordance with established protocols, investigations are underway to learn how the individual acquired the infection and to assess whether there are any further associated cases."

Video: Sweetener Effects on Gut Health - Dr. Kwangwook Kim

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Kwangwook Kim, Assistant Professor at Michigan State University, discusses the use of non-nutritive sweeteners in nursery pig diets. He explains how sucralose and neotame influence feed intake, gut health, metabolism, and the frequency of diarrhea compared to antibiotics. The conversation highlights mechanisms beyond palatability, including hormone signaling and nutrient transport. Listen now on all major platforms!

“Receptors responsible for sweet taste are present not only in the mouth but also along the intestinal tract.”

Meet the guest: Dr. Kwangwook Kim / kwangwook-kim is an Assistant Professor at Michigan State University, specializing in swine nutrition and feed additives under disease challenge models. He earned his M.S. and Ph.D. in Animal Sciences from the University of California, Davis, where he focused on intestinal health and metabolic responses in pigs. His research evaluates alternatives to antibiotics, targeting gut health and performance in nursery pigs.
