Victims tell their stories. Tanya came back from holiday in Costa Rica with a botfly maggot in her head. Zoe acquired her stubborn tapeworm on holiday in Africa, though it was two years before she noticed that anything was wrong. Silvio was urinating into the Amazon when a candiru fish swam up his urethra and for four agonising days lodged there with barbed determination until a surgeon sliced it out. Nick’s eyeball was eaten away from inside by a tiny Greek water parasite. Dr Marianne Parry visited Africa as a charity worker where she was infected by the Microscopic worm, which causes elephantiasis. This blocks the body's tissue-drainage system causing huge swellings of the limbs. There is no cure.
