Great update, shame that it has arrived on UK soil.
What I dont get is, why did it take DEFRA 2wks to confirm the disease?
There are rapid tests in use for the very reason of a rapid turn around.
ELISA and immunofluorescence (IF), are rapid and considered sufficient to initiate control measures. There are other molecular tests that are complete within a day.
Plus SVC is notifiable, whereas koi herpes virus is not. Under the right conditions KHV will wipe out more fish than SVC. Goldfish are not known to carry KHV.
