Scabies: Recognising and Treating the Whole Family
Quick Answer: Scabies — mite infestation announcing itself as night-dominant intense itch with tiny bumps and burrow-lines at finger-webs, wrists, waist, and folds — is cured only by the whole-household protocol: permethrin-cream application done correctly (neck-down coverage, the timing rules, repeated at one week) for every household member simultaneously — itchy or not — plus the same-day hot-wash-and-bag routine for bedding and clothes. Treat one person alone and the family ping-pong continues; the post-cure itch lasting weeks is dead-mite reaction, not failure.
Recognising the Pattern
The story diagnoses: itch that rules the nights, spreading through a household on a weeks-long fuse, mapped to the classic geography — finger-webs, wrist creases, elbows, waistline, buttocks, genital area in males, breast folds in females; infants break the rules (palms, soles, face involvement). Look for the burrows — fine wavy grey lines with a dot at the end — and the excoriated-bump landscape scratching builds; long-standing cases add eczematised patches and infection crusts. The examination (dermatoscopy can spot the mite's delta-wing sign) confirms what the night-itch-plus-family-spread story announced.
The Protocol That Actually Ends It
Everyone, the same night: permethrin 5% cream neck-down (face-scalp included for infants per instruction) on every household member — the asymptomatic carry mites through the itch-free early weeks, which is why "only the itchy ones" treatment fails on schedule; contact time per instruction (typically overnight), washed off, and repeated at day 7 to catch the hatch cycle. The same-day environment sweep: bedding, towels, and worn clothes into hot wash and sun; the unwashables bagged sealed for 3+ days (mites off skin die within days — the bag beats the panic-fumigation). The supportive tail: antihistamine itch cover, treating the secondary eczema-infection where scratching built it, and the crucial expectation — post-scabetic itch persists 2–4 weeks after successful cure (immune reaction to dead-mite material); re-treating monthly for a normal fading itch is the over-treatment loop the teaching prevents. Persisting-or-worsening itch beyond a month, or new burrows, earns the review — resistant cases and the crusted variant have escalation lanes (oral ivermectin protocols) at the visit.
FAQs
Is scabies a hygiene failure? No — close contact spreads it across every demographic; the shame delays the family treatment that cures it.
Do pets need treating? No — human scabies mites don't live on pets; the sweep is bedding-and-humans.
Can my child attend school during treatment? Post-first-application return is the standard guidance — confirmed at the visit with any school-policy note needed.
Why is everyone still itchy a fortnight after treatment? The dead-mite reaction paragraph above — fading trajectory means cure; new burrows mean review.
