Quantitative assessment of the effects of massive nucleic acid testing in controlling a COVID-19 outbreak.

ABSTRACT:

Background

From 20 July to 26 August 2021, local outbreaks of COVID-19 occurred in Nanjing City and Yangzhou City (Jiangsu Province, China). We analyzed the characteristics of these outbreaks in an effort to develop specific and effective intervention strategies.

Methods

Publicly available data on the characteristics of the COVID-19 outbreaks in Jiangsu Province were collected. Logistic regression was used to assess the association of age and sex with clinical severity. Analysis of onset dates, generation time distributions, and locations were used to estimate the mean transmission distance. A branching process model was used to evaluate different management strategies.

Results

From 20 July to 26 August 2021, 820 patients were diagnosed with COVID-19 in Jiangsu Provin
