Chickenpox cannot be confirmed or ruled out reliably from one photograph. If there is a new blistering rash or fever, your brother should be examined locally today before travel; avoid flying and close contact until the diagnosis is clear and any lesions have crusted. Do not start acyclovir or other medicines without a clinicianâs assessment. A medical certificate can be issued only after proper examination; I can review the case through a consultation.
Next Steps
Arrange an examination today and postpone travel until the doctor confirms fitness and infectious status. Keep the patient hydrated and avoid sharing towels or utensils.
Health Tips
Urgent review is needed for breathing difficulty, confusion, severe weakness, dehydration, persistent high fever or rapidly spreading rash.
