Abstract

Abstract

Objective This study aims to investigate the epidemiological characteristics of typhoid and Paratyphoid fever in China from 2004 to 2018, providing evidence for the prevention and control of these diseases. Methods Data on typhoid and paratyphoid cases and deaths from 2004 to 2018 were collected from the shared data Center of China Public Health Science and demographic data of the National Bureau of Statistics. Excel 2019 software was used to create a database of typhoid and paratyphoid fever. The joinpoint regression model was used to estimate the average annual percent change (AAPC) of typhoid and paratyphoid fever incidence in different age groups, provinces, and districts in China from 2004 to 2018. The changing trend characteristics of typhoid and paratyphoid fever incidence were then analyzed. Results From January 2004 to December 2018, a total of 18 195 cases of typhoid and paratyphoid fever were reported nationwide (the annual average incidence rate was 1.358 6/100 000), and the mortality rate was 0.326 1/1 000. From 2004 to 2018, both the incidence and mortality rate of typhoid and paratyphoid fever showed a downward trend (all P < 0.05). The incidence of typhoid and Paratyphoid fever from 2008 to 2018 showed an accelerated decline (APC: -24.96%, P < 0.001) compared to the period from 2004-2018 (APC: -4.10%, P=0.003). The incidence rates in 21 provinces showed a significant downward trend (all P < 0.05), 10 provinces showed a steady trend, and the incidence rate of the seven regions showed a downward trend. The annual average incidence rate in the seven regions showed a downward trend. The annual average incidence rate decreased the most in southwest China, and the least in South. The incidence of typhoid and paratyphoid fever was high in people under the 39-year-old group, and the highest incidence rate was in the 0- < 10-year-old group (1.906/100 000). The annual average mortality of typhoid and paratyphoid fever was the highest in the age group≥80 years old (1.363 6 / 1 000), and the mortality of patients over 30 years old showed a rapid increase with age. Conclusions From 2004 to 2018, the annual reported incidence of typhoid and paratyphoid fever in China shows a steady decline. There were still different degrees of epidemics and sporadic cases in different provinces, and the incidence decline was different. The incidence rate is higher in the 0- < 10-year-old group, and the mortality is higher in the≥80-year-old group. The situation of prevention and control of typhoid and paratyphoid fever should still be paid great attention to.
