Helen Johnson is a mathematical modeller at the European Centre for Disease Prevention and Control (ECDC) in Stockholm, Sweden. She uses models to illustrate how infectious disease may spread and to develop scenarios for planning interventions. She works at the interface of science and policy and has a particular interest in quantifying and communicating uncertainty, and in training and supporting infectious disease modellers in EU/EEA Member States and beyond.

Covid-19: Keeping a close eye on the models
As many European countries start to relax Covid-19 restrictions and reopen to foreign visitors whilst still rolling out vaccination programmes, it is more important than ever to stay one step ahead of the virus by accurately monitoring cases and predicting outbreaks.

An expert’s opinion: Interview with Helen Johnson on using mathematical models to forecast disease outbreaks
Helen Johnson, mathematical modeller at the European Centre for Disease Prevention and Control (ECDC), explains how modelling teams around the world are working together to develop accurate and timely predictions of Covid-19 cases and deaths in Europe. These forecasts have become an invaluable tool for making public health decisions. How did the European forecast hub ...
