The journal Science has published findings from a team of Chinese scientists that sea surface temperature anomalies in the Indian Ocean could help predict the size of the global dengue fever epidemic. Climate indicators can increase the ability to predict and plan for epidemics.
The report says Dengue fever is a disease caused by a flavivirus infection transmitted by mosquitoes. affecting almost half of the world’s population Meanwhile, climate events such as El Nino influence the dynamics of dengue fever epidemics around the world. Because it affects the reproduction of mosquitoes.
Xinhua news agency reported that researchers from Beijing Normal University used models of climate mechanisms and data on dengue patients from 46 countries in Southeast Asia and the Americas to discern the relationship between global climate patterns and the size of seasonal and annual dengue fever epidemics in both the Northern and Southern Hemispheres
The study results found that The model can provide early warning of dengue fever epidemics with a lag time of up to nine months, which is a significant improvement over previous models which could only provide early warning with three months of advance.
Tian Wai Yu The authors of the university study said the findings could help plan more effective responses to dengue outbreaks. But further evaluations are needed to evaluate the predictive performance of such models.
