In September 2025, mental health in young people was improved compared to previous research rounds. Compared to 2019, before the COVID-19 pandemic, children and young people did still have more frequent contact with the GP for suicidal thoughts and suicide attempts, feelings of anxiety and fatigue. These findings are from the seventeenth quarterly survey. The results of this study are part of Health Research for COVID-19.

In December 2024, 3% of young people indicated that they had symptoms for more than three months after a SARS-CoV-2 infection (post-COVID). Another 8% had had post-COVID before, but had recovered from it. Most post-COVID recovery occurs within six months, but we also see recovery after symptoms that lasted longer. These findings are from the fourteenth quarterly survey. The results of this study are part of Health Research for COVID-19.

In June 2025, there was a decrease in the percentage of adults that feel happy most of the time. However, mental well-being remained stable and confidence in the future increased. These findings are from the sixteenth quarterly survey. The results of this study are part of Health Research for COVID-19.The Network for Health Research in Disasters (GOR Network) publishes an update twice a year on this page, summarising results about adults from survey research and data from primary care providers. The results about young people are published in quarterly updates. The aim of this study is to provide information to municipalities, provinces and the national government of the Netherlands to assist them in formulating health policy, to facilitate better pandemic preparedness and equip them to mitigate the impacts of the COVID-19 pandemic. 

RIVM investigates the potential relation between the use of pesticides and Parkinson’s disease. RIVM is undertaking this study because there are significant concerns about this in society. Below, you will find information about the SPARK project (Strategies for regulatory assessment of Parkinson’s disease).

Het onderzoek van Dr. Fuminari Miura richt zich op de transmissiedynamiek van infectieziekten bij de mens. In het bijzonder is hij geïnteresseerd in hoe immuniteit en sociaal gedrag epidemieën vormgeven, en hoe verschillende empirische gegevens het overheidsbeleid kunnen informeren door middel van wiskundige modellering. Hij kwantificeert het effect van gerichte controlemaatregelen, met behulp van alternatieve methoden om ondergerapporteerde gevallen vast te leggen, en het meten van individuele heterogeniteit in vatbaarheid voor infectie. Hij is geïnteresseerd in het raakvlak tussen epidemiologische theorie en gegevensanalyse van infectieziekten - zelfs wanneer de beschikbare gegevens beperkt zijn, kunnen de resultaten van zijn onderzoek helpen de timing van preventieve maatregelen te optimaliseren. 

Dr. Kylie Ainslie is an infectious disease modeller at RIVM and an Honorary Assistant Professor at the University of Hong Kong. Her work at RIVM involves mathematical models of infectious disease transmission to determine the impact of vaccination strategies on disease spread, and the development of statistical methods to determine how vaccine-induced protection wanes over time. At the University of Hong Kong her work focuses on determining the real world protection provided by vaccines against respiratory diseases, such as COVID-19 and influenza.

The number of people with measles has increased significantly since January 2025. RIVM is researching whether wastewater surveillance can help monitor the spread of the measles virus. This research is still in a test phase to see what can be learned. It is not used in the efforts to control measles. This page presents how and why RIVM is doing the research, and what wastewater surveillance knowledge can add to existing methods for mapping the spread of measles.
