Overview
- RKI reports rising RSV detections in calendar week 3, around 4% of tested samples, a typical early warning for a wave that disproportionately affects infants and older adults.
- Influenza remains the leading driver of respiratory illness, accounting for about 60% of lab‑confirmed viruses, while SARS‑CoV‑2 stays at low single‑digit levels.
- Hospitals report heavier flu caseloads and operational strain in several regions, with Würzburg treating 52 influenza patients last week versus 29 in mid‑December, including some ICU needs.
- Genetic surveillance shows H3N2 Subclade K in roughly 70% of analyzed influenza A samples, with partial antibody escape linked to the season’s early and stronger onset.
- Health authorities urge influenza vaccination, targeted RSV antibody protection for high‑risk infants, and standard measures such as masking in vulnerable settings, ventilation, and hand hygiene.
