| 1 | Evidence of increasing risk of schistosomiasis among school-age children in municipality of Calatrava,Province of Negros Occidental,Philippines显示文摘Objective:To explore risk of school-age children being infected with schistosomiasis in selected villages in the municipality of Calatrava,province of Negros Occidental,Philippines.Methods:As part of the monitoring and evaluation of the helminth control program in the province of Negros Occidental,parasitological monitoring,through the use microscopy of stool samples processed using Kato-Katz technique,was conducted to describe the baseline and follow-up parasitological status of school-age children in 2010 and 2012.respectively.Seven villages from the municipality of Calatrava were selected as study sites.Results:During baseline assessment,only one case of schistosomiasis was reported from the village of Marcelo.During follow-up assessment,32 cases(6.9%) of schistosomiasis were reported and the prevalence of moderate-heavy intensity infection was 13% in six villages.Among the seven villages included in the follow-up,Minapasuk had the highest prevalence at 14.6%.while San Isidro reported no case of schistosomiasis.Conclusions:Non-endemic villages,which have reported positive cases in school-age children,may need to be assessed for possible cndemicity for schistosomiasis.Transmission of the disease may need to be determined in these villages through active parasitological and malacological surveillance.Other nonendemic villages adjacent to or share river networks with endemic villages in Calatrava may need to be explored for possible introduction of the disease,especially after typhoons and Hooding.Establishing endemicity for schistosomiasis in these villages will help infected and at risk individuals to receive yearly treatment to reduce morbidities caused by this disease. | Belizario VY Jr Erfe JM Naig JRA Chua PLC | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，5： | 1 |
