Brief Summary
Background:The impact of the emergence of SARS-CoV-2 variants on the severity and clinical outcomes of COVID-19 is controversial. Whether virological characteristics including the mutational patterns of the different viral proteins (e.g., Spike, NSP proteins, ORF6) could be associated with a different immune response and subsequent severity of the disease is unknown. ln the next coming months, new variants carrying the same or new mutational patterns will continue to emerge. Monitoring their dynamics over time and their impact on disease severity is required for refining national and international disease control policies. Main objective: To unravel the relationships between specific viral mutations/mutational patterns and the clinical outcomes of COVID-19 in patients hospitalized in intensive care units (ICUs) for acute respiratory failure following severe SARS-CoV-2 infection. Design of the study Prospective multicentre observational cohort study Schedule for the study: Inclusion period: 24 months; Participation period: 28 days ; Total duration : 24 months + 28 days;

Outcome Measures
Primary Outcomes (1)
Day-28 vital status
vital status (living / deceased)
at Day-28 after admission in intensive care units (ICUs) for acute respiratory failure following severe SARS-CoV-2 infection
Interventions
Nasopharyngeal swab available in Standard Of Care (SOC) will be analysed (Full-length SARS-CoV-2 RNA sequencing and Transcriptomic analyses)
Eligibility Criteria
Patients with severe SARS-CoV-2 infection and acute respiratory failure admitted in one of the participating ICUs during 2 years of inclusion period.
You may qualify if:
- Age ≥ 18 years.
- Availability of nasopharyngeal swab from SOC
- SARS-CoV-2 infection as assessed by a positive RT-PCR test (CT \< 32), including in SARS CoV-2 vaccinated or previously infected patients
- Patient admitted in the ICU for acute respiratory failure (SpO2 ≤ 90% and need for supplemental oxygen or any kind of ventilator support; i.e., OMS 10-category ordinal scale ≥5)
- Patient or trusted person or close or relative, And, accepting study participation
You may not qualify if:
- Patient with SARS-CoV-2 infection but no acute respiratory failure
- Patient deprived of liberty or under legal protection (guardianship, curators, legal protection, forced hospitalization)
