Varicella zoster virus guideline

This guideline focuses on managing varicella zoster virus (chicken pox and shingles) in the workplace, providing evidence-based guidance for occupational health professionals. Separate summary leaflets provide advice to employees and employers dealing with varicella zoster virus in the workplace, with specific advice for those in the healthcare sector.

Summary of findings:

• Healthcare workers diagnosed with chickenpox should be excluded from the workplace until there are no new lesions and all lesions have crusted over.
• Susceptible healthcare workers who have a significant exposure to VZV should either be excluded from contact with high-risk patients or inform their occupational health department if they feel unwell or develop a rash or fever during the incubation period.
• Decisions about restrictions should be taken in conjunction with the healthcare worker, their manager and infection control, while respecting the worker’s right to medical confidentiality.
• Pregnant healthcare workers exposed to chickenpox or shingles should be assessed by an OH or other appropriate health professional.
