Frequently Asked Questions (FAQs): General

  • A lady in our area claims that her dog ate meat from the carcass of a horse thar died as a result of AHS and now states that her dog has also now died of AHS. Is such a thing at all possible ?
    Answered: 1/4/2008, 15:14 by James Urry.
    See the answer.
  • Reporting AHS is compulsory - who registers the cases on this site - is it compulsory or voluntary. We have had severe outbreaks with several deaths in the Benoni/Bredell area yet the 184 reported cases seem low compared to what we have been hearing country-wide?

  • I am not sure if my horse has AHS or equine encephalosis. What are the differences between the 2?

  • Some one told me that you can check to see if a horse has AHS but looking under the tongue, and if you find white marks/blisters under the tongue then they do have AHS. Is this correct?

  • If there are no zebras close, where do the midges get infected blood. Do the midges travel far or Can the virus survice in ticks?
    Answered: 5/3/2008, 16:05 by Douglas Welsh.
    See the answer.
  • If you look at the statistics then we will notice that there was a big drop in cases reported from 05-06 to 06-7 and hopefully we will see the same trend for 07-08. Why do you think it is that the survial rate has dropped significantly. In 05-06 82% of horses survived if they contracted AHS. In 06-07 only 45% survived and for the current year 07-08 only 40%? ?

  • I understand that the racing industry has provided a lot of funding to fight AHS. If this virus over-winters in animals like zebras,what if we treat zebras during winter months to kill the virus which they carry? It is a state controlled disease and couldn't the state vet implement such an effort? ?

  • If a mare dies from AHS and leaves a very young foal,what are the chances of that foal developing AHS?

  • Kilacoidis - I have heard that they are light senstive.Is this true or are they attracted to light? I have also heard that they cannot be seen with the naked eye.Is this true?

  • How, when and where do the midges breed? And what measures can be taken to stop them in their tracks?
    Answered: 12/2/2008, 10:16 by Douglas Welsh.
    See the answer.
  • Several horses died in the Western Cape last year, but my understanding is that they all had encephalosis, and not AHS. Is this correct? Is there anything one can do to protect the horses against encephalosis, apart from trying to stop the midges biting them?
    Answered: 11/2/2008, 20:05 by Douglas Welsh, James Urry.
    See the answer.
  • If a horse has survived AHS dikkop are they still at risk for the rest of the season or do they have some extra immunity?
    Answered: 11/2/2008, 16:56 by Douglas Welsh.

  • Do donkeys carry AHS?

  • Please provide ALL the symptoms for AHS. What should we look out for?
    Answered: 29/1/2008, 10:28 by Douglas Welsh.
    See the answer.
  • If AHS is spread by midges who are infected, how do the midges become infected in the first place? Is it not because of innoculating our horses that the midges biting them are spreading the horse sickness from the injected horses?
    Answered: 5/1/2008, 16:08 by Douglas Welsh, James Urry.
    See the answer.
  • Do "indigenous" breeds like the Nooitgedacht pony show lower incidence/mortality rate to AHS than breeds that made their way more recently into South Africa?
    Answered: 2/1/2008, 20:06 by Douglas Welsh, James Urry.
    See the answer.
  • When a horse had AHS, for how long afterwards can't you ride it? I work on a game reserve in the Waterberg area and we have 28 horses. They all work hard and if one is off duty, that means the others have to work even harder, so the sooner I can start using the horse that had AHS, the better, but obviously I don't want to rush him into working again?
