Knowledge, attitudes, and practices about COVID-19 in Argentina. A cross-sectional study

Our objective was to assess levels of knowledge, attitudes, and practices against COVID-19. A total of 3774 persons were surveyed between September 18 and October 16, 2020. Eighty% resided in Buenos Aires City or Buenos Aires Province: 58% had completed tertiary education; 72% worked either independently or as employees in the public or the private sector; 51% used a prepaid health care plan, 34% were covered by a trade union-based health system, and near 10% used the public health services. According to the socio-demographic variables analyzed, the population studied was representative of the middle class. A total of 7% had been diagnosed with COVID-19. There was a high level of knowledge about the disease, judging by the high proportion of correct answers (80-90%). Regarding the measures taken by the government, the answers varied widely ("correct", "inadequate", "harmful", "unnecessary", etc.). The medical staff was the preferred source of information; 44% of respondents felt protected by their health system; 28% would only seek healthcare when feeling very sick. There was a high degree of compliance with most protection measures, except for attendance to social events in poorly ventilated spaces (50%). The results of these studies contribute to establishing communication strategies for the prevention and control of COVID-19 and thus deal more efficiently with eventual outbreaks of the disease.
