Parasitic Worms CASE FILE On July 19, the director of a children's day camp notified the health department of three campers who had received a diagnosis of a skin condition. The camp included a main building, swimming pools, volleyball court, playground with a sandbox, picnic area, and beach for boating and swim- ming. Approximately 300 campers and 80 staff members attended each camp session. On July 20, all current campers their parents, and staff members were notified about the three ill chil- dren. Parents were asked to look for symptoms of infection, including a snake-shaped (serpiginous) red rash, itching, and pus-containing skin lesions. Twenty-two reports of persons with signs or symptoms of the disease were received. All but two patients used a nonprescription topical ointment at home before seeking medical attention. Patients were treated with thiabendazole, mebendazole, albendazole, or ivermectin. All 22 patients participated in the half-day camp for children ages 2 to 6 years. Although campers and staff members for both the half- day and full-day camps were exposed to sand from the beach and the volleyball court, only those in the half-day camp were allowed in the playground area, which included a sandbox containing sand that had been placed in the box 2 years previously. Fourteen of the 22 who became ill did not wear shoes while in the sandbox. Investigators observed cats around the playground sandbox and noticed animal feces inside the sandbox. After analyzing initial data, the health department determined that the sandbox was the source of infection. Two feral cats were removed from the premises by animal control. Health department staff recom- mended that the sandbox be covered with a tarp when not in use to prevent future fecal contamination and to change the sand regularly.Explanation / Answer
Giardia, helemints are the campers infected. Hikers and campers who drink water from streams get this infection
