ObjectiveTo collect information on: concerns about personal health due to the spread of COVID-19; health precautions taken in response to COVID-19; job situation; and flu vaccination intentions.To offer statistics on the evolution of the disease and its burden on the population, coupled with some statistics on labour force statusTo estimate prevalence of the population by immunological status Obtain precise estimates of the immunological status of the population, monitor the evolution of the epidemic, and identify the most significant risk factors for SARS-CoV-2 infection. To understand how many people have developed antibodies to Coronavirus, even in the absence of symptoms.Obtain precise estimates of the immunological status of the population, monitor the evolution of the epidemicTo estimate prevalence of symptomatic and asymptomatic SARS-CoV-2 infection in the general population and how this varies over time
