Squirrels Could Make Monkeypox a Forever Problem

In the summer of 2003, just weeks after an outbreak of monkeypox sickened about 70 people across the Midwest, Mark Slifka visited “the super-spreader,” he told me, “who infected half of Wisconsin’s cases.” Chewy, a prairie dog, had by that point succumbed to the disease, which he’d almost certainly caught in an exotic-animal facility that … Read more

Demonstrating varying pathogenicity and tropism of SARS-CoV-2 variants in a feline model

In a recent study posted to the bioRxiv* pre-print server, researchers at Cornell University College of Veterinary Medicine and the University of Illinois Urbana-Champaign compared the infection dynamics, pathogenicity, and tissue tropism of multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants in adult cats. A new wave of SARS-CoV-2 breakthrough infections is occurring around … Read more

Pets living in households with COVID-19 are high likely to seroconvert and become ill

In a recent study published in the journal Emerging Infectious Diseasesresearchers investigated whether pet dogs and cats in the households of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected humans were at risk of infection. Study: Risk Factors for SARS-CoV-2 Infection and Illness in Cats and Dogs. Image Credit: Sharomka/Shutterstock Studies have demonstrated that several species … Read more
