Season totals by region

Summary of laboratory tests for respiratory viruses by region for the running season (since calendar week 40/2025). Prague and Central Bohemia share virological laboratories and report jointly; the Zlín region has no virological laboratory of its own in the reports.

Laboratory tests by region — season 2025/26

Absolute counts per season: positive detections and samples tested. Regional differences mainly reflect laboratory capacity, not just disease occurrence.

Where the data comes from

Every week the SZÚ website publishes a PDF with laboratory results by virological site. The pipeline downloads and parses them into a continuous time series — published PDFs never change retroactively, so a downloaded week is final. The extraction is validated against cumulative totals inside the PDFs.

Processing of personal data

What we collect

Web server access log — IP address, time, page address, browser type and referring page. Deleted after 14 days.

Visit counts by organisation — the IP address is resolved to an organisation (for example “Charles University”) and discarded. Only counts are kept. They are not personal data.

Which pages are read — our own analytics running on our server, with no cookies and no device identifier. The data does not go to third parties.

On your device we store a single item, and only so that this notice does not appear on every visit. It is not an identifier and it goes nowhere.

Your rights

You have the right of access to your data, to rectification or erasure, to restriction of processing, to object, and to lodge a complaint with the Czech Data Protection Authority.

⚠️ In practice: we cannot find you in the access log unless you tell us the IP address and roughly when you visited — we keep nothing else to search on.
