Background: The COVID-19 pandemic was a global health emergency and crisis that affected both the well-being and the economy of citizens.Objective: The aim was to evaluate the degree of involvement, viral load and immunological response to the SARS-CoV-2 virus, in 18-65-year-old adults who performed essential tasks in the municipality of Andratx (Balearic Islands, Spain), compared to those who did not perform them, as well as the 2-18-year-old children of both groups if there were any.Materials: Both groups were monitored between the months of July 2020 and February 2021, in which the degree of involvement, the viral load and the immunological response to the SARS-CoV-2 virus were analyzed, using questionnaires, PCR tests and ELISA serology tests.Results: A positive case of RT-PCR test was found in screening the general population. The highest 2019-nCoV(N)-Ig antibody levels in plasma were from 1 to 17 February 2021, with following percentage of positives: 6.8% of essential workers, 9.5% of essential worker son, 7.3% of non-essential worker and 2.2% of non-essential worker son. However, the increase in levels of anti-SARS-CoV-2 (N) immunoglobulin G (IgG) and anti-SARS-CoV-2 (N) immunoglobulin M (IgM) were produced in session 3, from 9 to 25 November 2020, in both cases in non-essential workers, with a mean of 218.1 ng/mL of anti-SARS-COV2(N) IgG and 31.3 ng/mL of anti-SARS-COV2(N) IgM .Conclusion: The control measures taken to control the COVID-19 pandemic in the municipality of Andratx, Mallorca, Spain, were effective.
