About this dashboard
This dashboard hosts the sequencing efforts and its results of the ReVSeq (Respiratory Virus Sequencing) study carried out in Switzerland. It brings together, for each sample, when and where it was sequenced, how well its genome was sequenced, and how the sequences relate to known lineages. Relevant metadata are also attached to each sample.
The data
The dashboard contains 649 viral genome sequences collected across Switzerland between 2023 and 2025, covering 13 respiratory viruses (with RSV-A and RSV-B shown separately). The 2023/24 season was a non-targeted survey of respiratory viruses; the 2024/25 season targeted specific viruses. Each sample comes with its sampling date, canton and diagnostic PCR result, so sequencing and PCR detections can be compared side by side. Nine samples were found by sequencing to carry more than one virus.
What you can see
- Home: weekly sequencing and PCR detections of all viruses. Hover over a bar to see how often sequencing and PCR agreed.
- Virus pages (choose one in the drop-down menu):
- detections over time and a map by canton, with a weekly time slider;
- sequencing depth along the annotated genome, for all samples, per subtype or per sample, to spot poorly covered regions;
- an interactive phylogenetic tree (Nextstrain/Auspice) placing the study samples among publicly available genomes.
- Co-infections: which viruses were found together in the same sample, and the sequencing depth of each.
How it is built
The dashboard is built with ReVSeq Visuals, an open-source framework for turning viral sequencing data into an interactive dashboard. It uses Nextclade and Nextstrain for the phylogenies. Other groups can build a dashboard for their own data by following the step-by-step tutorial.
