What our notes say
- Classic scabies: papular, non-painful rash — interdigital webs, wrists, elbows, armpits, genitals; never above the head; severe nocturnal pruritus, worse after hot bath; scratching → secondary infection (YEAR 3 PARASITOLOGY NOTES)
- Immunosuppression — measles causes lymphopenia and immune suppression lasting weeks → window for secondary infections (EXAM: Hepatitis Viruses, Oncogenic Viruses, Paramyxoviruses & Arboviruses)
- Secondary infection (reactivation) can also transmit but causes less severe disease (EXAM: Vaccines & Antivirals, Rabies, CMV & EBV, Adenovirus & Enteroviruses)
- Toxic Epidermal Necrolysis (TEN) — large areas of epidermis slough → fluid loss + secondary infection, similar to burn injuries. (Pathology of Acute Skin Inflammation: Urticaria & Eczema)
- Stasis predisposes to secondary thrombophlebitis and secondary infection (VASCULAR PATHOLOGY — Must-Know Comprehensive Notes)
