Methodological note

Information on the incidence of COVID-19 in Catalonia comes from the Ministry of Health (dadescovid.cat). Data are shown for Catalonia by full weeks (from Monday to Sunday) and include exclusively the cases confirmed by positive active infection diagnosis test (PCR and antigen test). Neither IgM antibody serological tests nor ELISA tests are included, because they provide information on the immunological state of the person, but not on the date when the virus was active. In contrast, the accumulated figure of confirmed cases in Catalonia includes those confirmed by PCR, antigen tests (ATs) serological tests, ELISA tests and the epidemiological and probable cases.

The imputed date is the start of the case, which is the earliest date between the date on which a health issue is diagnosed with COVID-19 symptoms in Primary Healthcare (provided the diagnosis is 14 days before the PCR/AT) and the date on which the positive PCR/AT result arrives. If a person has more than one COVID-19 diagnosis, the first one in the last 14 days is the one taken. If a person has undergone more than one PCR/AT, the first one is taken, which is the test that confirms the case.

The reproduction number (Rt) of an epidemic measures the average number of people infected by a person who has the virus. It is calculated as Rt= ( N(t) + N(t-1) + N(t-2) ) / ( N(t-5)+ N(t-6) + N(t-7) ), where N is the number of cases confirmed by PCR/AT.

Data on deaths in Catalonia include all those that specify in the death certificate that the person died due to COVID-19, whether or not they have a positive PCR.

Information on the incidence of COVID-19 in Spain comes from two sources:

  • The data of PCRs/ATs performed and the percentage of positive PCRs/ATs come from the European Centre for Disease Prevention and Control (ECDC).
  • The confirmed case data, the confirmed case rate and death figures come from the daily statements of the Spanish Ministry of Health. Idescat makes an estimate of the weekly confirmed cases in Catalonia and the rate of weekly confirmed cases in Spain to correct any delay in the reporting of the information. The estimate is carried out on the basis of the data communicated by the Ministry of Health of cases diagnosed in the last 7 days, cases diagnosed in the last 14 days and total cases.

Data from Spain for PCRs/ATs performed and positive PCRs/ATs do not include serological tests for IgM antibodies. In contrast, confirmed cases and the confirmed case rate include cases confirmed by a positive active infection diagnosis PCR, antigen test (AT) and by serological tests with compatible symptomatology.

Data from Catalonia and Spain may vary as a result of retrospective revisions, and may show oscillations or inconsistencies arising from the editing and validation processes. The total of confirmed cases and the total deaths may include some old cases in addition to new ones.
