Scrapings from a patient's rash reveal cercariae.The disease is most likely

Question

Quizplus · Accepted Answer

The presence of cercariae in the rash scrapings indicates that the patient is suffering from swimmer's itch, which is a type of allergic reaction caused by parasitic infection with certain species of schistosomes. This condition typically occurs after exposure to contaminated freshwater bodies, such as lakes or ponds, and presents with itching, redness, and small papules or blisters on the skin. Lyme disease, Rocky Mountain spotted fever, relapsing fever, and Chagas' disease are all caused by different types of pathogens, such as bacteria or parasites, and present with different symptoms, such as fever, fatigue, muscle aches, and organ damage. Therefore, they are not the most likely diagnoses given the presented information about cercariae in the rash scrapings.
