Context

The European Centre for Disease Prevention and Control (ECDC) is the EU’s agency for epidemiological surveillance, headquartered in Stockholm. It coordinated the COVID-19 response and monitors infectious diseases across the EU. It publishes sensitive data on disease outbreaks and vulnerable population groups. Governed by Regulation (EU) 2018/1725. HAR: 98 requests, 3 page sessions, 2 domains.

What the HAR shows

Two domains — www.ecdc.europa.eu and webtools.europa.eu. Three page passes (requests repeat at +6422 and +12394 ms) — the session covered several pages. Zero external trackers, zero Set-Cookie responses. The standard europa.eu pattern: the theme, the global banner (webtools.globan.js), the translation tool (webtools.etrans), flag icons.

Sensitivity context

ECDC processes epidemiological data, including information on disease outbreaks, infection spread, and at-risk groups. For an agency handling potentially sensitive public health data, the absence of external trackers matters particularly. Visitors to the ECDC site — researchers, physicians, journalists — should not be profiled by advertising networks.

Conclusion

98 requests, 2 europa.eu domains. The infectious-disease agency upholds the EU institutions’ standard: zero external trackers, zero cookies, only European infrastructure.
