Frequently Asked Questions (FAQs)

Do the midges which spread AHS already have the AHS virus after breeding or do they only contract it after biting an infected animal, and can then spread the disease?

Asked: 11/11/2007, 16:52 by Tertia Thackwray.
Answered: 12/11/2007, 15:29 by Douglas Welsh, James Urry.

Much research has been done on the cycle of the midge and it is clear that the midge has to take a blood meal from an infected horse to be able to pass the virus onto the next horse. ( when in a breeding cycle midges take multiple blood meals before they lay eggs) What we still do not know is where the virus over-winters. It is assumed that it over-wintersin a host animal like a zebra, donkey or mule.
