Incidence of dengue and chikungunya viruses in mosquitoes and human patients in border provinces of Vietnam. A climate-driven dengue early warning system would allow public health decision-makers to design, implement, and target timely interventions to the most at-risk places. Conclusions This study shows that by combining detailed Earth observation data, seasonal climate forecasts, and state-of-the-art models, dengue outbreaks can be predicted across a broad range of settings, with enough lead time to meaningfully inform dengue control.
The spatial distribution of the posterior mean of the Model predictions could also be portrayed using risk maps Fig 8 so that users can be made aware of the high-risk areas.

Parasit Vectors. First, while our modelling framework incorporates important determinants of dengue occurrence such as climate and urbanisation, it does not explicitly incorporate, at Borborodud alamaya stage, the potential effects of other important determinants of disease such as the deployment of mosquito control interventions, vector indices, serotype-specific circulation, herd immunity, and the mobility of people and goods, all of which may lead to significant changes Dth the level of risk experienced locally [ 91 ].
Following our results, however, we recommend the use of the 95th percentile as a threshold for outbreak detection as it gave slightly better results for detecting outbreaks. Monaghan, A.
