COVID-19 in The Netherlands: Exploring Forecasts and Interventions

Prediction is hard, especially about the future. While mathematical models by no means guarantee accurate predictions, they at least formalize the process through which one arrives at them. This allows one to criticise their assumptions and, in the event of eventual failure, pinpoint where and why they went wrong. With respect to COVID-19, van Wees […]

Smoothening the Rocky Road Towards Open Science

In my last blogpost, I discussed the importance of as well as the rocky road leading towards Open Science during the corona crisis. To the disappointment of many scientists, almost no data about the corona crisis was publicly available at the time. However, a lot has changed since my last blog post; the rocks on […]

Using Insights from Network Science to Open up Offices More Safely

Many aspects of life require that humans are in physical contact with other humans. We can think of people as nodes in a network and contact between them as defining the edges of the network. Unsurprisingly, this contact network plays a key role in virus transmission. This suggests that we can use insights from network […]

Visualising the COVID-19 Pandemic

The novel coronavirus has a firm grip on nearly all countries across the world, and there is large heterogeneity in how countries have responded to the threat. Some countries, such as Brazil and the United States, have fared exceptionally poorly. Other countries, such as South Korea and Germany, have done exceptionally well. Many countries have […]

Why we need to take manual contact tracing (more) seriously

In April, the Dutch government announced its intention to develop a corona-app that could be used in contact tracing. Other countries like China (Vervaeke, 2020), Australia, Singapore, the United Kingdom and Norway are already implementing or piloting such an app (Servick, 2020). However, concerns over the privacy of the app may be as widespread as […]

Interactive exploration of COVID-19 exit strategies

The COVID-19 pandemic will end only when a sufficient number of people have become immune, thus preventing future outbreaks. Principally, so-called exit strategies differ on whether immunity is achieved through natural infections, or whether it is achieved through a vaccine. Countries across the world are scrambling to find an adequate exit strategy, with differential success. To mo...

The Rocky Road Towards Open Science

Open Science is a movement which aims to make scientific research transparent and accessible to all levels of society (Woelfle, Olliaro & Todd, 2011). Open Science has different goals, such as making science more verifiable and results reproducible, thus more reliable. There is also a political and moral argument for Open Science: a lot of […]

Corona strategies in different European countries: how are things working out?

This blog post was written by Dewi Jager, part of the Exit Strategy Bulletin team.  During uncertain times, we tend to look to others for information. In these Corona days, it might be useful to look at the actions of other countries for our next steps. Right now, we are at the beginning of a […]

Benchmarking challenge

In my view, the discussions regarding the transparency of the epidemiological modelling ought to lead to a more constructive assessment of the reliability of such models. While I have not worked on models in this field, I do have experience with assessing methods for data analysis where similar concerns played a role. For that reason, […]

Wat is de beste strategie voor testen op Covid-19?

This blog post was written by Prof. Henk van Beijeren. Nu de lockdownmaatregelen versoepeld worden is het van het grootste belang uit te vinden hoe de te verwachten toename van het reproductiegetal R voor zover mogelijk kan worden tegengegaan door optimaal te testen en traceren. Uitgangspunt voor optimaal testen is dat het aantal tests, indien mogelijk wordt […]
