What this means
In week 33 of 2026, activity of respiratory syncytial virus (RSV) in Greece is low. The trend, derived from clinical surveillance, is stable.
Data, context and methodology
The current picture for Greece is built on the European Respiratory Virus Surveillance Summary (ERVISS), published weekly by the European Centre for Disease Prevention and Control (ECDC). the National Public Health Organization (EODY) via the sentinel GP network is the national public-health authority that feeds ERVISS with sentinel primary care and virology data.
ECDC ERVISS
ERVISS is ECDC's weekly pan-European surveillance summary for influenza, SARS-CoV-2 and RSV. National authorities, in Greece's case the National Public Health Organization (EODY) via the sentinel GP network, submit harmonised indicators every week, which ECDC publishes in a standardised dataset on Thursdays. Using ERVISS rather than each country's native portal ensures cross-country comparability.
ILI / ARI consultation rates and positivity
the National Public Health Organization (EODY) via the sentinel GP network operates a sentinel network of general practices that report weekly rates of patients consulting for influenza-like illness (ILI) or acute respiratory infection (ARI). A subset of patients is swabbed and tested by reference laboratories, producing pathogen-specific positivity rates for flu, SARS-CoV-2 and RSV.
Why this source
Combining consultation incidence with virological positivity yields a pathogen-specific weekly incidence signal (ILI × positivity / 100). This is the standard European methodology and provides a more robust view than either indicator alone: consultation rates capture illness burden, positivity confirms which pathogen is driving it.
Qualitative classification
The “low”, “moderate” and “high” categories follow seasonal reference values and epidemiological thresholds calibrated to match our classifications for other countries. The ILI × positivity / 100 product is scaled to comparable thresholds using a divisor of 3, which aligns European sentinel peaks with the consultation-equivalent scale used elsewhere. Data refreshes weekly when ECDC publishes the latest ERVISS update, typically on Thursdays.
Source and seasonal pattern by pathogen
- Influenza
- The classification is based on the ECDC ERVISS weekly reports, drawing on data from the National Public Health Organization (EODY) via the sentinel GP network. Seasonally, infection waves in Greece typically peak between December and February; activity is usually markedly lower during the summer months.
- COVID-19
- The classification is based on the ECDC ERVISS weekly reports, drawing on COVID-19 surveillance data from the National Public Health Organization (EODY) via the sentinel GP network. Seasonally, infection waves in Greece typically peak during winter, with occasional summer waves driven by new variants; activity is usually markedly lower in late spring between waves.
- RSV
- The classification is based on the ECDC ERVISS weekly reports, drawing on RSV surveillance data from the National Public Health Organization (EODY) via the sentinel GP network. Seasonally, infection waves in Greece typically peak between December and February; activity is usually markedly lower in spring and summer.
Frequently asked questions
When is RSV season in Greece?
RSV activity in Greece 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. EODY publishes RSV indicators within its weekly respiratory-virus surveillance alongside flu and SARS-CoV-2.
Who is most at risk from RSV in Greece?
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 Greece?
Since 2023, RSV vaccines have been authorised in the EU for older adults and for passive protection of infants. Greece has begun introducing the long-acting monoclonal antibody nirsevimab for infants entering their first RSV season, and adult RSV vaccines are recommended for defined risk groups in line with EODY guidance. Uptake and clinical impact are monitored through weekly surveillance.
How is RSV tracked in Greece?
RSV surveillance in Greece combines sentinel GP data, virological testing coordinated by EODY, and hospital-admission signals for severe paediatric and adult respiratory infection. Weekly results are published by EODY and also reported to ECDC ERVISS, which lets Greece's RSV curve be compared directly with Italy, Cyprus, and other EU/EEA countries.
How does RSV differ from flu in Greek data?
In EODY 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.
