Therefore, to eradicate the problem of prevalence of Schistosomiasis in the Dongting Lake area, we must implement a set of systematic plans to reconvert farmland to lakes, that is, to gradually relocate the population in the lake area and change the existing farmland into lakes to recover the past vast surface of the Dongting Lake and reestablish biological balance in the lake area, so that human beings and the creature Schistosome can again coexist in harmony in nature.
