The ‘Early Health Warning System’ is a weather-based advanced warning system to detect disease outbreaks. It is currently being developed by the Ministry of Earth Sciences. The system is to be based on the relationship between changes in weather, like rainfall and temperature patterns and disease incidence. Eg: increase in rainfall linked to malaria. This will help predict outbreaks of vector-borne diseases like diarrhoea and malaria. It could also help monitor outbreak of non-communicable diseases.
