Abstract

Objectives:

This study aimed to investigate the epidemiological characteristics of syphilis between 2013 and 2018 in the Haidian District of Beijing in China. In addition, this study suggests potential strategies to control the spread of syphilis infection.

Study Design:

Observational study.

Methods:

Data were collected from the Infectious Disease Reporting System at medical institutions within the Haidian District of Beijing between 2013 and 2018. Epidemiological methods, combined with Chi-squared test, were used to analyse the distribution of syphilis in terms of time, region, population and development stage.

Results:

In total, 3048 patients with syphilis were reported in the Haidian District between 2013 and 2018, with an average annual prevalence of 14.26 per 100,000 population. The prevalence of syphilis was higher in rural than urban regions, and the sex ratio of male-to-female was 1.52:1. Patients aged 20-29 years accounted for 22.60% (689/3048) of the total cases. In terms of occupational distributions, the highest proportion (30.61%; 933/3048) was seen in individuals who were homemakers or unemployed. Latent syphilis was present in 66.83% (2037/3048) of patients and accounted for an increased proportion of syphilis cases each year.

Conclusions:

Syphilis was epidemic in the Haidian District of Beijing between 2013 and 2018. High prevalence was seen in young and middle-aged males living in urban areas. The prevalence of syphilis has been increasing since 2016; thus, public health policies and intervention strategies need to be strengthened to curb the spread of infection.

Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Prevalence and Incidence

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
