(Based on recommendations from Cohen et al):
Skin exposures where skin remains intact do not carry a risk of transmission and no further assessment or follow up is required.
For all other injuries, proceed to the injury risk assessment below

Treatment of possible cases of Herpes B disease
Any patients presenting with fever, flu-like symptoms, vesicles at site of injury or signs of encephalopathy following an injury with a non-human primate should be immediately discussed with the ID registrar on-call (pager 8161 9am-7pm, ID Consultant on-call via switchboard out with these).
Assess Rabies risk as per PHE rabies post-exposure guidelines
Follow *NHS Lothian antimicrobial guidelines for management of animal bites (For prophylaxis use the recommendations for human bites).
All monkey bites are considered “tetanus prone”. Recommended actions are given in the table below and are based on PHE guidance.
