Andorra's Respiratory Virus Season Stable at Low Levels in Week 12
ARI steady at 123.4 cases per 100,000, with metapneumovirus leading detections; Europe sees declining flu and returning baseline activity amid ongoing RSV in children.
Key Points
- Andorra ARI stable at 123.4 cases per 100,000 in week 12, highest in children 0-4.
- ILI low at 3.4 cases per 100,000, all in adults 25-64.
- Metapneumovirus leads detections at 50%, followed by rhinovirus at 30%.
- Europe sees declining flu, baseline activity, but elevated RSV in young children.
Andorra's respiratory virus season remains stable at low levels during week 12 of the 2025-2026 period, aligning with a continuing decline across Europe.
The Ministry of Health reported acute respiratory infections (ARI) at 123.4 cases per 100,000 inhabitants, unchanged from the prior week. Children aged 0-4 continued to bear the highest burden, while influenza (ILI) incidence stayed low at 3.4 cases per 100,000, below epidemic thresholds. All detected flu cases occurred among adults aged 25-64, indicating limited overall circulation.
Virological surveillance showed 10% of tested samples positive for respiratory viruses. Human metapneumovirus predominated at 50%, followed by rhinovirus/enterovirus at 30%. Influenza A and adenovirus each made up 10% of positives.
In Europe, primary care activity has returned to baseline following winter peaks, with flu circulation and hospitalizations dropping further. A(H3) and A(H1N1)pdm09 subtypes remain the main strains. Respiratory syncytial virus (RSV), however, continues elevated continent-wide, especially among children under five, who account for the majority of related hospitalizations. SARS-CoV-2 activity persists at low levels with minimal complications.
