Outcome Measures

Primary Outcomes (1)

  • Cumulative incidence of SARS-Cov2 infection in the general population.

    Simple and corrected estimate of the number of seropositive individuals/number of individuals at risk in different strata, based on weighting and calibration and taking into account the random cohort effect.

    8 months

Secondary Outcomes (6)

  • Maintenance over time of the acquisition of anti-SARS-Cov2 antibodies

    8 months

  • Rate of use of care (medical care, hospitalization, center 15) linked to the occurrence of symptoms suggestive of a SARS-Cov2 infection, and share attributable to the infection

    8 months

  • Proportion of infections without reported or pauci-symptomatic symptoms and their epidemiological and social determinants

    8 months

  • Proportion of tests proposed, accepted, performed, based on social and demographic characteristics

    8 months

  • Proportion and intensity of use of barrier measures (hydroalcoholic gel, mask, social distancing, description of outings / reasons, duration, frequency) and association with the level of seroprevalence

    8 months

  • +1 more secondary outcomes
