Stage 3: Proof of Concept
Targeting one village with praziqantel treatment and education curriculum, the prevalence of liver infection declined from 67% to 16%. An intensive "liver fluke-free school" program was added to schools, which included stool examination, treatment, health education, exhibitions and curriculum focusing on liver fluke infection and liver cancer. The baseline infection in 9 schools was initially 9.2% and has now been reduced to zero. This year 9 schools were certified as liver fluke free schools.
Three years ago, Dr. Sripa and colleagues initiated a pilot project (the Lawa Model) in the Lawa Lakes region of Khon Kaen.
Dr. Sripa and colleagues employed an integrated bottom-up approach, targeting villages with treatment and intensive educational curriculum, to decrease liver infection.
How does your innovation work?
Human liver flukes, O. viverrini, O. felineus and C. sinensis remain important public health problems in many parts of the world. Recent reports suggested that about 35 million people are infected with C. sinensis globally; with up to 15 million human infections in China and another 8--10 million individuals infected with O. viverrini in Thailand and Laos. This pilot targeted villages with praziqantel treatment and an intensive education curriculum (IEC).
