Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the B65 range.
Cercarial Dermatitis
A pruritic rash that occurs as consequence of cercariae penetration of the skin after aquatic exposure to animal (usually avian) schistosomes, often in countries non-endemic to human schistosomiasis. The condition is non-invasive and responsive to symptomatic treatment.
Schistosomiasis
Infection with flukes (trematodes) of the genus SCHISTOSOMA. Three species produce the most frequent clinical diseases: SCHISTOSOMA HAEMATOBIUM (endemic in Africa and the Middle East), SCHISTOSOMA MANSONI (in Egypt, northern and southern Africa, some West Indies islands, northern 2/3 of South America), and SCHISTOSOMA JAPONICUM (in Japan, China, the Philippines, Celebes, Thailand, Laos). S. mansoni is often seen in Puerto Ricans living in the United States.
