System to catch fatal fever early
Print Edition
RESEARCHERS have developed an early warning system to predict the risk of dengue fever infections in south China’s Guangdong Province, authorities said yesterday.
The system uses real-time information on the weather, infection distribution and mosquito density to produce risk estimates up to two months in advance, said Ma Wenjun, head of the provincial Center for Disease Control and Prevention’s institute of public health.
Ma said the information would be used to direct disease prevention and control strategies.
Dengue is a mosquito-borne, potentially fatal disease that mainly affects people in tropical and subtropical regions, causing fever, nausea, as well as aching muscles and joints.
Guangdong is a major dengue epidemic area, with the peak season for dengue between June and October.
“The dengue epidemic is related to many factors including climate, rainfall, El Nino, local population density, sanitation and human migration,” said Ma, adding that the earlier prevention and control measures were taken, the more effective the results would be.
The system has been installed at county-level disease control centers in the province to control and contain dengue epidemics.
