  • Measure the impact of safety measures

Health monitoring

What is the expected impact of a vaccination strategy? Can the spread of the flu epidemic be predicted during winter in France? … Thanks to real-time information systems and mathematical modelling, it is possible to offer epidemiological forecasts which contribute to more effective prevention and control of diseases, in particular, infectious diseases.

OpenHealth modelled, from the analysis of medicine sales in pharmacies, Advanced Health Indicators for the major seasonal diseases (flu-like syndromes, allergies, gastro-enteritis etc.). These indicators are updated daily and made available in open data on

OpenHealth Company works on the development of predictive algorithms in conjunction with public health and epidemiology research teams, and by working with renowned applied Mathematics laboratories such as CentraleSupelec with whom a partnership has been entered into.
