Reinfection, exposure and immunity in human schistosomiasis.
In this review Paul Hagan will focus on the results of the reinfection studies that have been completed on Schistosoma mansoni in Kenya and Brazil and on S. haematobium in The Gambia. The review will also draw on the data from other immunological, molecular and epidemiological studies that have provided information that may be relevant to an understanding of immunity in human schistosomiasis. No attempt will be made to describe the latest advances that have been reported from studies of the animal models of schistosomiasis; these are adequately dealt with elsewhere.
