Orf is a skin infection you can get from infected sheep or goats. It most often affects the fingers, hands, forearms or face. It usually clears up without treatment in about 6 weeks.

How you get orf

Orf is a virus that mainly affects young lambs and goats.

You can get it if you have a sore, cut or scratch that touches an infected animal. You're most at risk if you have regular contact with sheep or goats – for example, if you're a farmer or if you bottle feed a lamb.

Orf causes scabs around the animal's nose and mouth, which may spread to their legs and teats. It's not usually serious but is passed easily between animals.

Sheep and goats can be vaccinated against the orf virus. But people can get infected if they come into contact with recently vaccinated or unvaccinated animals.

It's very rare for orf to be passed from one person to another.

The blister is usually 2 to 3cm, but it can grow up to 5cm. It may leak fluid before crusting over.

Other symptoms of orf include:

  • a high temperature
  • general tiredness (fatigue)
  • swollen glands on the inside of your elbow or under your arm

See a GP if:

  • you have a mark or blister on your finger, hand, arm or face that has got bigger or not healed after 6 weeks
  • you have a mark or blister that's painful, red and swollen, and you have a high temperature
  • you have a rash that looks like a target or "bulls-eye", with a dark centre, surrounded by a paler ring and a darker ring around the outside
  • you have lots of blisters, or big, painful blisters, or blisters that keep coming back

Treatments for orf

There's no specific treatment for orf.

The blister on your skin should clear up in around 6 weeks. Cover it with a waterproof dressing to keep it clean and dry and stop it getting infected.

If it becomes infected, you may need antibiotics.

Rarely, minor surgery may be needed to remove the affected area of skin if it does not clear up by itself.
