The study published in the journal Science suggested that climate indicators could enhance forecasting and planning for outbreak responses, Xinhua news agency reported.

Dengue is a mosquito-borne flavivirus disease that affects about half the world's population. Climate events such as El Nino are known to influence dengue transmission dynamics globally by affecting mosquito breeding.

Using climate-driven mechanistic models and data on dengue cases reported in 46 countries in Southeast Asia and the Americas, researchers at Beijing Norma University examined global climate patterns and the seasonality and interdiction of dengue epidemics in both the Northern and Southern hemispheres. -Identified relationships between annual quantities.

The study showed that the model has the ability to warn of dengue with a significant lead time of up to nine months, which is a significant improvement over previous models that could only warn three months in advance.

The university's Tian Huiyu, corresponding author of th paper, said the findings could allow more effective planning for outbreak response, but further assessments are needed to evaluate the predictive performance of th models.
