Abstract

The COVID-19 pandemic placed heavy burdens on the health of people and the health systems of governments around the world. Since 2020, Vietnam has had 4 outbreaks of COVID-19. This study was carried out by a retrospective cross-sectional descriptive method with all COVID-19 infections in the fourth wave of Bac Ninh in 2021 (5/5/2021 - 27/12/2021). Among 10,717 cases, the average age is 28.95 years old, of which the main age group is from 15 to 39 years old, accounting for 70.44%; occupational diseases with the highest risk of infection are workers, accounting for 60. 94%; infection from contact among colleagues in the same agency or same company accounts for the highest rate up to 61.88%. Que Vo 1 Industrial Park has the highest number of cases in the province, accounting for 68.15%. The number of cured cases was as high as 99.84% and the number of deaths accounted for 0.16%. The coordinated application of timely and reasonable measures such as accelerating testing and vaccination against COVID-19 has helped Bac Ninh province to control the number of cases and effectively prevent more infection. Our study provides important evidence on the epidemiology of the 4th COVID-19 epidemic, which was mainly recorded in industrial areas and from there in the community.
