#Cat Death Losses Due to Highly Pathogenic Avian Influenza in #SouthDakota

Updated January 13, 2025

"#Veterinarians and laboratory diagnosticians are fielding reports of death losses in cat populations linked to avian influenza infections.

"Beginning in 2022, an #H5N1 subtype of highly pathogenic avian influenza (abbreviated as HPAI) virus caused death losses in domestic turkeys and chickens in South Dakota and elsewhere in the United States, an outbreak that continues. The HPAI virus causes respiratory and multiple organ failure in affected birds, typically appearing as increased numbers of dead birds in large commercial operations, as well as smaller backyard flocks. Deaths in wild birds, typically migrating waterfowl but also other bird species, have been observed at the same time, as well as spillover of the virus into mammals, such as raccoons, foxes, skunks, and other species.

"In Spring 2024, the HPAI virus began infecting #DairyCows, causing drops in milk production and other signs of illness. Unlike infections in other species, widespread death losses have not been associated with HPAI infections in dairy cows.

"About the same time as its emergence in dairy cows, the HPAI virus was implicated in deaths of domestic cats in the vicinity of affected farms. Most affected cats showed #neurologic signs, such as #tremors or #seizures, for a short period of time before dying.

"Since that time, three cases of substantial death losses in groups of outdoor domestic cats in South Dakota have been described. In each of these cases, there has been no apparent link to dairy cows, other livestock, or domestic poultry."

As science teachers using NGSS, we don't just teach facts. We use storylines to connect facts into a larger picture. A fun way to get students interested in evolution can be to use clips from fun science fiction movies.

Many kids have seen the Tremors series of movies, featuring the fictional animal, Graboids. While fictional, we can ask - if they were real, how could they have evolved? With careful observation and Socratic questioning we inspire students to posit what form of life they could have evolved from - in doing so we cover natural selection, convergent evolution, and clades and phylogenies!
