The "Rule of 7s" for Lyme disease is a clinical tool, primarily for children with suspected Lyme meningitis, that identifies low-risk patients based on three criteria: less than 7 days of headache, less than 70% cerebrospinal fluid (CSF) mononuclear cells, and no facial (7th) cranial nerve palsy, allowing for outpatient management while awaiting definitive test results, but clinical judgment is still crucial. There's also a general "rule of 7s" emphasizing early treatment (within 7 days), potential progression (7 weeks), and chronic forms (7 months) for Lyme management in broader contexts, though this is less a formal rule and more a guideline for timeliness.
