Case study for TWiP 95 Daniel's patient for this week is a 28 yo single female, returns from beach vacation with new boyfriend. Two weeks in Central America (Belize). Often found secluded beaches. Good health, noticed upon her return had small nodules/papules on front of thighs. Thought were insect bites, became very itchy. Noticed serpiginous red lines forming, radiating out from bumps. Felt things moving in her skin. Benadryl did not help. Daniel say something similar occurs in Lima. Healthy, no allergies, surgeries, no relevant family history, using barrier contraception, sexually active. Only drinks alcohol socially. Boyfriend did not report symptoms. She did lie on sand, used thin fabric. Stayed in hotel. There were wild dogs on beach. During her stay she ate ceviche. No intestinal symptoms.
