- has 3 stages
what are the 3 stages for lyme disease
stage 1- multiple erythematous papules that itch, sting or burn (summer/early fall - outbreaks)
stage 2- appears weeks to months later; characterized by meningitis, cranial nerve palsies, and peripheral neuropathy
stage 3- oligoarticular arthritis
treatment for lyme disease
- doxycycline, amoxicillin, or erythromycin for 10-21 days
patho for scabies
eggs laid by sarcoptes scabiei mite in stratum corneum then will hatch into larvae, will hatch in 3-4 days and will reach adulthood in 2 months

small, erythematous papules, itching, dry scale or crust around finger webs, wrist, umbilicus, and groin area
treatment for scabies
topical permethrin cream
patho for lice (pediculosis)
