Researchers are trialling a new computer-based early warning system in Vietnam that could help reduce dengue cases by up to 25 per cent. By combining climate data, historical infection records and artificial intelligence, the system aims to predict outbreaks up to three months in advance. Sydney-based General Practitioner Dr Anil Gupta says early warning and prevention are crucial, as dengue cases are rising globally due to climate change and increased travel. Experts believe this proactive approach could ease pressure on health systems and serve as a model for other dengue-prone regions, including parts of the Asia-Pacific.
