RESUMEN

OBJECTIVE: To evaluate the epidemiological evolution and economic impact of COVID-19 pandemic in the European Union (EU) and worldwide, and the effects of control strategies on them. MATERIAL AND METHODS: We collected incidence, mortality, and gross domestic product (GDP) data between the first quarter of 2020 and of 2023. Then, we reviewed the effectiveness of the mitigation and zero-COVID control strategies. The statistical analysis was done calculating the incidence rate ratio (IRR) of two rates and its 95% confidence interval (CI). RESULTS: In the EU, COVID-19 presented six epidemic waves. The sixth one at the beginning of 2022 was the biggest. Globally, the biggest wave occurred at the beginning of 2023. Highest mortality rates were observed in the EU during 2020-2021 and globally at the beginning of 2021. In mitigation countries, mortality was much higher than in zero-COVID countries (IRR=6.82 [95% CI: 6.14-7.60]; p<0.001). A GDP reduction was observed worldwide, except in Asia. None of the eight zero-COVID countries presented a GDP growth percentage lower than the EU percentage in 2020, and 3/8 in 2022 (p=0.054). COVID-19 pandemic caused epidemic waves with high mortality rates and a negative impact on GDP. CONCLUSION: The zero-COVID strategy was more effective in avoiding mortality and potentially had a lower impact on GDP in the first pandemic year.

RESUMEN

The aim of this study was to promote the rapid identification of the contacts of patients infected with SARS-CoV-2 and therefore the control of the pandemic. Different methodologies and recommendations on contact tracing for Primary Health Care (PHC) and Public Health Services (PHS), like articles in Pubmed about COVID-19 and contact tracing, official contact definitions, the classic contact tracing model in tuberculosis (TB), information about apps for contact tracing and the role of the diagnostic tests, were reviewed. To establish efficient prevention and control measures, it is always necessary to implement contact tracing based on clinical suspicion, early diagnosis and isolation of cases and contacts and their follow-up. The classic contact tracing model in TB can be applied to this new infection, but accelerating the process given its acute nature and its potential severity. Good coordination between PHC and PHS and having sufficient resources is essential.
