What is Orf?
  • Orf is a viral disease that is widespread in sheep and goats.
  • Orf can be transmitted to humans in contact with infected animals.
  • orf is also known as
  • ‘soremouth, Contagious
  • ecthyma or scabby mouth’.
s ymptoms
Symptoms

These symptoms include..

  • painful red skin lumps.
  • Blisters
  • Skin infection on hands.
  • Skin infection on forearms.
  • Swollen armpit and lymph glands.
causes
Causes
  • Soremouth is the most common skin disease affecting sheep and goats. It is a highly contagious disease caused by a virus in the "pox" family.
  • Soremouth affects all breeds of sheep and goats. The disease tends to be more severe in goats than sheep.
prevention
Prevention
  • Soremouth is best prevented by maintaining a closed and virus-free herd.
  • After a herd is infected, it is difficult to eliminate the disease because the virus can remain stable in the crusts.
  • The virus is a tough one. It contains proteins that interfere with the hosts immune and inflammatory responses.
  • The soremouth virus can survive for months, possibly years, away from the sheep.
  • The vaccine may be used in outbreaks.
  • Affected animals can be isolated, while unaffected animals can be vaccinated to reduce the severity of new cases and shorten the course of infection.
treatment
Treatment.
  • Treatment of soremouth is usually unrewarding. Because it is a virus, soremouth does not respond to antibiotics.
  • Treatment does not speed the course that usually takes one month.
  • It is recommended that the crusts not be removed, as this may delay healing, promote scarring, and increase the handler's chance of picking up the disease.
  • While most adult animals with lesions on their lips continue to eat and produce milk, it may be too painful for young lambs and kids to suckle or eat dry feed.
can humans suffer from it
Can humans suffer from it?
  • People can get infected with the soremouth virus when they come into contact with infected or recently-vaccinated animals.
  • Handling the live vaccine can also result in infection.
  • It is important to observe good personal hygiene and to wear gloves when treating infected animals.
