Incidence and characterization of profiles of low / high risk of complications in people> 60 years with COVID19.

Population-based cohort study, with a 4-month retrospective-prospective follow-up (03/01/2020-30/06/2020), which will include 48,000 people> 60 years of age from Tarragona (1,500 of them institutionalized). Objectives: (i) to know the real incidence of COVID-19 infection, discriminating according to "confirmed" (PCR +) and / or "suspected" cases (COVID19-like without PCR confirmation); (ii) identify the frequency of presentation (initial and during evolution) of symptoms and signs of the disease in both types of patients (confirmed / suspected); (iii) characterize the clinical presentation profile (symptoms and signs) of COVID-19 infection in the population and explore prediction models for low / high risk of complication profiles (sudden worsening, need for hospitalization / ICU, death) based on possible predictor covariates (sex, age, symptoms / signs, comorbidity and previous medication).
