Rabbit Hemorrhagic Disease (RHD) is a fatal disease caused by a calicivirus that affects only rabbits. USDA considers RHD a foreign animal disease and has recently detected the Rabbit Hemorrhagic Disease Virus Serotype 2 (RHDV2) in North America. RHDV2 is not known to pose health risks to humans, livestock, or pets other than rabbits. The first detected case of RHDV2 was in Washington state in February 2018. Ohio saw a case in September 2018 and again in Washington in July 2019.
Cedar-apple rust is a common plant disease caused by the fungal pathogen Gymnosporangium juniperi-virginianae. It infects members of the Rosaceae and Cupressaceae families, primarily apple, crabapple, eastern redcedar, and other juniper species. Cedar-apple rust is a widespread disease across the continental U.S. and is a common issue for apple producers due to the prevalence of redcedar and juniper as ornamental plants in landscapes.
