[Construction of platform of Schistosoma japonicum infection real-time monitoring and early warning along Yangtze River].

OBJECTIVE: To construct a platform for Schistosoma japonicum infection real-time monitoring and early warning in marshlands along the Yangtze River. METHODS: The data of the status of Oncomelania hupensis snails, schistosomiasis endemic situation, marshland environment status, and other basic information were collected and analyzed comprehensively in marshlands along the Yangtze River in Jiangsu Province, and a schistosomiasis endemic situation electronic map was established. Through the GPS and 3G technology, the short messaging service (SMS) alerts were sent to the fishermen when they entered the areas of different schistosomiasis endemic levels in real-time. RESULTS: The SMS alerts reminded the fishermen to adopt the suitable interventions to reduce or avoid the schistosome infection. In addition, the data of moving track of mobile phones of fishermen, and the examination and treatment of schistosomiasis at each monitoring point were collected and analyzed comprehensively and then systematic analysis reports of schistosomiasis situation prediction, early warning, related evaluation, etc. were created in real-time. CONCLUSION: The platform for Schistosoma japonicum infection real-time monitoring and early warning in marshlands along the Yangtze River has a certain application value for schistosomiasis prevention and control work of Jiangsu Province and even whole country.

[Surveillance of schistosomiasis in a national surveillance site of Yangzhong City, 2005-2009].

A longitudinal survey of schistosomiasis was carried out in Shicheng Village, Yangzhong City, Jiangsu Province, a national schistosomiasis surveillance site, from 2005 to 2009. The results showed that the infection situation of schistosomiasis in residents, and the status of snails, in general, remarkably decreased from 2005 to 2009. However, the snails still existed, so the comprehensive control in marshland and surveillance of infectious sources should be strengthened.

[Malaria endemic and control in Yangzhong City from 1979 to 2010].

In Yangzhong City, the incidence of malaria decreased gradually from 883.48 per hundred thousand in 1979 to 0.36 per hundred thousand in 2010. The incidence was 0 from 2005 to 2009, but 1 local infected patient was found in 2010. The achievements of malaria control are significant, however, with the development of economy, the increase of mobile population, and the dimness of malaria control consciousness, the control strategy should be adjusted in order to eliminate malaria.

[Surveillance of schistosomiasis in a national surveillance site of Yangzhong City, 2005-2010].

The surveillance of schistosomiasis in Shicheng Village, a national schistosomiasis surveillance site in Yangzhong City from 2005 to 2010 showed that snail areas were 16.43 hm2, the occurrence rates of frames with living snails and mean densities of living snails exhibited a declining trend year by year, and the infected snails were only found in 2007. The sero-positive rates in residents were 1.81%, 0.98%, 0.29%, 0.28%, 0.47% and 0.51%, respectively from 2005 to 2010. However, no stool-examination -positive persons were detected. During the period, no acute infections occurred, and no advanced cases and infected animals were detected. It is indicated that schistosomiasis has been effectively controlled in the surveillance site. However, snails remain present, so comprehensive control and surveillance of infectious sources should be further strengthened.
