Andorra Respiratory Virus Activity Stable in Week 12 with Slight ARI Rise
Influenza cases dropped sharply below thresholds, while metapneumovirus led virological positives; trends align with Europe's declining circulation and elevated RSV hospitalizations.
Key Points
- Andorra ARI incidence rose slightly to 145.71 per 100,000 in week 12, stable overall.
- Influenza cases dropped sharply to 5.74 per 100,000, below thresholds.
- Metapneumovirus led virological positives at 44.44%, followed by rhinovirus at 33.39%.
- Trends match Europe's declining flu and elevated RSV hospitalizations.
Respiratory virus activity in Andorra held steady during week 12 of the 2025-2026 season, with acute respiratory infection (ARI) incidence at 145.71 cases per 100,000 inhabitants from 16 to 22 March. This marked a slight rise from 131.61 the prior week, though levels remained contained and aligned with European trends of declining circulation.
Children aged 0-4 years bore the heaviest burden from ARI, followed by the 15-24 group. Influenza incidence dropped sharply to 5.74 cases per 100,000—well below epidemic thresholds—from 12.93 the previous week. Among flu cases, young adults aged 15-24 showed the highest rates, with overall virus activity in clear descent.
Virological tests yielded positive results in 11.99% of samples (one report noted 11.39%). Metapneumovirus dominated at 44.44%, followed by rhinovirus/enterovirus at 33.39% (or 33.33% per one source). Adenovirus and respiratory syncytial virus (RSV) each made up 11.11%.
Across Europe, doctor visits for respiratory symptoms have returned to baseline in most countries, signaling a post-winter slowdown. Flu circulation continues to fall, though RSV activity remains elevated with high hospital admission rates. SARS-CoV-2 levels stay low across all age groups, with limited hospitalizations.
