Frequently asked questions
When is RSV season in Iceland?
RSV activity in Iceland typically begins rising in late autumn, peaks between December and February, and fades into spring. Post-pandemic seasons have been less predictable than pre-2020 patterns, with earlier or delayed peaks in some years. Because the population is small, individual weeks can show noisier signals, so Landlæknir and Landspítali draw attention to multi-week trends rather than single data points.
Who is most at risk from RSV in Iceland?
The groups at highest risk of severe RSV are infants (particularly those under six months, preterm babies, and infants with underlying heart or lung disease) and older adults, especially those aged 75 and above or with chronic respiratory or cardiac conditions. In otherwise healthy children and adults, RSV usually resembles a common cold and resolves without complications.
Are RSV vaccines and nirsevimab available in Iceland?
Since 2023, RSV vaccines have been authorised in the EU/EEA for older adults and for passive protection of infants. Iceland has progressively adopted the long-acting monoclonal antibody nirsevimab for infants entering their first RSV season, and adult RSV vaccines are recommended by Landlæknir for defined risk groups. Uptake and clinical impact are monitored through weekly surveillance at Landspítali.
How is RSV tracked in Iceland?
RSV surveillance in Iceland combines primary-care consultation data, virological testing at Landspítali, and hospital-admission signals for severe paediatric and adult respiratory infection. Weekly results are published by Landlæknir and also reported to ECDC ERVISS, which allows Iceland's RSV curve to be compared directly with Norway, Denmark, and other EU/EEA countries. Cross-country comparison is particularly useful given Iceland's small sample size.
How does RSV differ from flu in Icelandic data?
In Landlæknir and Landspítali surveillance, flu and RSV appear as separate positivity streams within the same respiratory panel. RSV disproportionately affects infants and the very elderly, while flu burden spreads across age bands and is especially severe in older adults. Symptom overlap between the two viruses is wide, so the distinction relies on laboratory testing rather than clinical impression.
