Abstract: Objective To understand distribution patterns and influencing factors for the interval between onset and diagnosis of typhus in China, and to provide a scientific basis for accurate prevention and control of typhus. Methods Descriptive statistical methods were used to analyze the distribution patterns of the interval between onset of disease and diagnosis. The Kruskal-Wallis H test was conducted for statistical difference analysis. Multivariate logistic regression was used to analyze the influencing factors. Results A total of 29 211 typhus cases were reported in China from 2005 to 2017. Those cases were from 29 provinces (autonomous regions and centrally administered municipalities). The median interval between onset of disease and diagnosis was 7 days. The interval was between 0 and 20 days for 92.20% of the cases. The median interval between onset of disease and diagnosis was 6 days for males and 7 days for females. Students and scattered children had longer time intervals between onset of disease and diagnosis than others. Hebei, Guangdong, and Shandong provinces had shorter time intervals, while Sichuan and Liaoning provinces had longer time intervals. Conclusion There is a long interval between onset and diagnosis of typhus in China. To accurately diagnose, treat, prevent, and control typhus, action should be taken to specifically address this issue.
