Project RSV ComNet

PijnRationale

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory infections in children. By the age of one year, 60-70% of the children have been infected by RSV and almost all children have been infected by two years of age.
In Western countries, mortality due to RSV is rare. Hospitalization rates in young children are estimated to be 0.6 to 42.7 cases per 1000 children, with higher rates in younger children. Accurate estimates of the burden of RSV, including in primary care, are necessary to assess the overall impact RSV has on the society. This knowledge is critical for policymakers to make informed decisions regarding the introduction of new RSV interventions.

Doel Aim of RSV ComNet

The aim of RSV ComNet is to measure the clinical and socio-economic disease burden of RSV in young children (aged <5 years) in primary care.

OrganisatieProject design and planning

The project was started in 2019 and continued in the winter of 2020/2021 and 2021/2022. It consist of the following steps:

  • RSV ComNet III: Measuring the clinical and socio-economic disease burden of RSV infections in young children in primary care in five European countries – winter 2021/2022
    In the winter of 2021/2022 data collection has been extended to five European countries, namely United Kingdom, Netherlands, Italy, Spain and Belgium. The plan is to write two papers on the data collected in the study. The first focusing on the clinical burden of RSV in young children in primary care, including complications after an RSV episode and the second on the socio-economic burden, including costs, and population-based estimates of RSV infections in young children in primary care. The progress of the data collection for RSV ComNet III is reported in an infographic, which will be regularly updated.

  • RSV ComNet II: Measuring the clinical and socio-economic disease burden of RSV infections in young children in primary care – winter 2020/2021
    The standardized disease burden protocol, developed in and updated after the evaluation in RSV ComNet I is shown below. The burden of RSV in young children will be measured in the Netherlands and the United Kingdom in the winter of 2020-2021. Both countries have chosen to use the infrastructure of the sentinel routine influenza surveillance network to recruit children for the RSV ComNet study. Data collection was extended over the summer because there was no RSV circulation in the winter of 2020/2021 due to the COVID-19 pandemic.
  • RSV ComNet I: Development and evaluation of the standardized disease burden protocol to measure the clinical and socio-economic disease burden of RSV infections in young children in primary care – winter 2019/2020
    The focus of RSV ComNet I was to develop and evaluate a standardized disease burden protocol to measure the clinical and socio-economic disease burden of RSV infections in young children (<5 years) in primary care. The second aim was to evaluate whether the infrastructure of existing sentinel surveillance networks of general practitioners (GPs) or paediatricians are appropriate for patient recruitment. The standardized disease burden protocol was evaluated in the Netherlands and Italy during the 2019/2020 winter. The results of the RSV ComNet I study are summarized in the infographic Measuring the burden of RSV among young children in primary care. Results of the RSV ComNet pilot in Italy and the Netherlands and published in BMC infectious Diseases.

MondkapjeImpact of the COVID-19 pandemic

Due to the COVID-19 pandemic and the related non-pharmacological interventions (NPIs) there was hardly any RSV circulation in the winter of 2020/2021. This was also seen in in the winter of 2020 in countries in the Southern hemisphere, such as Australia and South Africa. Therefore, we have written a publication about the levels of RSV circulation in the winter of 2020/2021 in Europe, and the expectations for the coming summer and autumn/winter 2021/2022. This paper is published in Eurosurveillance. The main conclusions from this paper were that it is likely that the non-pharmaceutical interventions inhibited the RSV activity, especially the closure of schools and day-care facilities, and future RSV epidemic(s) could start outside the usual winter season and might be larger than usual.

COVID-19 vaccines are now available and every European country has launched a COVID-19 vaccination program. This led to the relaxation of the COVID-19 measures. Therefore, we expect the impact of the COVID-19 pandemic to be smaller in the 2021/2022 winter.
