If you are a vet with a patient with Myxomatosis or a rabbit guardian whose rabbit has been diagnosed with Myxomatosis, please email us at myxomatosis@rabbit.org.
Myxomatosis is a reportable disease in California. The California Department of Food and Agriculture’s Animal Health Branch tracks outbreaks. Tracking myxomatosis outbreaks teaches us more about the disease and how to prevent it. Please report cases to the CDFA’s animal health branch at 916-900-5002.
If you are a vet in California, please submit deceased rabbits suspected of Myxomatosis for necropsy with a CAHFS state lab (fee $135) or report confirmed Myxomatosis cases to the California Department of Food and Agriculture (CDFA): evet@cdfa.ca.gov.
We want to thank Dr Hilary Stern, DVM, DABVP for her many Myxomatosis reports.
