Milker’s Nodule

Aetiology

• Parapoxvirus infection acquired from cows’ teats.

• Typically transmitted via direct contact with infected bovine lesions.

• No human-to-human transmission reported.

Clinical Features

• Incubation Period: ~5–14 days

• Lesions:

  • Small, firm, red–blue, flat-topped papules/nodules on hands, fingers.

  • May develop a greyish surface or form crusts.

  • Usually solitary or multiple (2–5 lesions).

• Generally painless, though mild tenderness can occur if secondarily infected.

Management

• Self-Limiting: Typically resolves within 4–6 weeks without scarring.

• Cover Lesions: Reduce the chance of bacterial superinfection.

• Antibiotics: Only if secondary infection occurs (e.g. local cellulitis).

• Education: Advise on hand protection (gloves) when handling potentially infected animals to prevent reinfection or new lesions.
