Time | Phase | Specific Methods |
---|---|---|
1981–1984 | Warren’s Study Control | Guifan Village: People with a positive stool examination result should receive drug chemotherapy. Sanlian Village: 1. People with positive result of stool examination should receive drug chemotherapy. 2. The areas where snail lived were sprayed with molluscicide every spring. |
1985–1991 | Local Government Control | 1. Chemotherapy for people and cattle was the basic measure. 2. Health education for people. 3. Molluscicide was directed at the susceptible areas. |
1992–2001 | World Bank Loan Project | Goal: Enhanced morbidity control through praziquantel to human and bovines. Details: 1. Chemotherapy was complemented by health education. 2. Snails were controlled by environmental management. 3. Molluscicide was a key way to sustain transmission control. |
2002–2004 | Extended Period of WBLP Control | 1. Achievements from WBLP were not reinforced. 2. The extent of chemotherapy shrinked and compliance of chemotherapy became worse. 3. Returning farmland to lake was advocated due to the molluscicide and previously reclaimed land from the lake. |
2005–2017 | Integrated Strategy Control | 2005: 1. Chemotherapy with praziquantel for people and cattle. 2. Snail control with molluscicides. 3. Health education programmes—residents should stay away from snail-infested areas and water Since 2006: 4. All cattle were replaced with mechanized equipment. 5. Other domestic animals were fenced in. 6. Piped water and lavatories were supplied to improve sanitation. |
