COVID-19 in Spain
Current COVID-19 activity in Spain — based on ECDC ERVISS weekly data, set against the parallel flu and RSV trajectories.
Current situation: COVID-19
In week 15 of 2026, activity of COVID-19 in Spain is low. The trend — derived from clinical surveillance — is falling. Over a four-week comparison, a clear decline is visible.
The classification is based on the ECDC ERVISS weekly reports, drawing on COVID-19 indicators from Spain's SiVIRA surveillance system operated by the Instituto de Salud Carlos III (ISCIII). Seasonally, infection waves in Spain typically peak during winter, with occasional summer waves driven by new variants; activity is usually markedly lower in late spring between waves. How severe a given season becomes depends on the circulating virus variant and the population's immune status, among other factors.
Data sources and methodology
The current picture for Spain is built on the European Respiratory Virus Surveillance Summary (ERVISS), published weekly by the European Centre for Disease Prevention and Control (ECDC). SiVIRA (Instituto de Salud Carlos III, ISCIII) 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 Spain's case SiVIRA (Instituto de Salud Carlos III, ISCIII) — 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
SiVIRA (Instituto de Salud Carlos III, ISCIII) 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.
Frequently asked questions
How is COVID-19 monitored in Spain today?
With population-wide testing wound down, COVID-19 in Spain is now tracked inside the SiVIRA integrated surveillance system run by ISCIII. Indicators include sentinel primary-care consultations, hospital and ICU admissions for severe acute respiratory infection, virological positivity, and variant characterisation. Weekly bulletins are published nationally and Spanish data also feeds the ECDC ERVISS dashboard.
Is COVID-19 still a serious concern in Spain?
COVID-19 is now endemic in Spain and continues to cause hospitalisations and deaths each winter, concentrated in older adults and people with weakened immune systems. For most vaccinated adults with prior infections, current variants tend to cause illness similar to a bad cold or flu. Long COVID is followed through dedicated studies. Risk is managed via targeted boosters rather than population-wide restrictions.
When do COVID-19 waves happen in Spain?
COVID-19 in Spain has not locked into a single seasonal rhythm. A winter wave overlapping with flu and RSV has recurred each year since 2020, but additional waves have occurred in spring and late summer when new variants with an immune-escape advantage have emerged. Variant surveillance by ISCIII is therefore watched alongside hospitalisations for early signs of a resurgence.
Who can get a COVID-19 booster in Spain?
Spain's autumn COVID-19 booster campaign is targeted at groups advised by the Comisión de Salud Pública, typically including adults aged 60 or 65 and over, people with comorbidities, pregnant women, residents of long-term care facilities, and healthcare and social-care workers. Eligibility is reviewed each season, and uptake is reported alongside flu coverage through ISCIII and the Ministerio de Sanidad.
Are new variants still being tracked in Spain?
Yes. Routine sequencing in Spain detects new sublineages and feeds ISCIII's variant reporting. Most emerging variants cause illness broadly comparable to their predecessors, but occasional lineages with clear immune escape can drive faster, larger waves. Variant trends are reported in the SiVIRA bulletins and shared via the ECDC ERVISS platform for European-level comparison.
