Age-specific transmission dynamics under suppression control measures during SARS-CoV-2 Omicron BA.2 epidemic.

Background: From March to June 2022, an Omicron BA.2 epidemic occurred in Shanghai. We aimed to better understand the transmission dynamics and identify age-specific transmission characteristics for the epidemic.

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

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.

Effect of different interventions for latent tuberculosis infections in China: a model-based study.

Background: Tuberculosis (TB) has a serious impact on people's health. China is one of 30 countries that has a high TB burden. As the currently decreasing speed of the incidence of TB, the WHO's goal of "End TB Strategy" is hard to achieve by 2035.

Prediction of different interventions on the burden of drug-resistant tuberculosis in China: a dynamic modelling study.

Background: Tuberculosis (TB) is one of the top 10 causes of death worldwide. The World Health Organization adopted the 'End TB Strategy' to end the global TB epidemic by 2035. However, achieving this goal will be difficult using current measures.

Impact of immunization programs on 11 childhood vaccine-preventable diseases in China: 1950-2018.

To evaluate the achievements of China's immunization program between 1950 and 2018, we chose 11 vaccine-preventable diseases (VPDs) as representative notifiable diseases and used annual surveillance data obtained between 1950 and 2018 to derive disease incidence and mortality trends. Quasi-Poisson and polynomial regression models were used to estimate the impacts of specific vaccine programs, and life-table methods were used to calculate the loss of life expectancy, years of life lost, and loss of working years. The total notification number for the 11 VPDs was 211,866,000 from 1950 to 2018.
