Summary
Sexually transmitted infections (STIs) in Korea show a decade-long trend of declining bacterial infections and increasing viral infections like genital herpes and human papillomavirus (HPV). Public health strategies must adapt to these changing STI patterns.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Background:
- Analysis of major sexually transmitted infections (STIs) in Korea from 2010 to 2021.
- Investigation of epidemiological shifts and prevalence changes over a decade.
Purpose of the Study:
- To examine the prevalence and epidemiological trends of bacterial, viral, and other STIs in Korea.
- To identify changes in STI patterns, including age-specific prevalence and gender differences.
Main Methods:
- Utilized Korean Health Insurance data from 2010-2021.
- Analyzed patient diagnoses based on ICD-10 codes.
- Examined annual trends and age-specific prevalence for various STIs.
Main Results:
- Trichomoniasis was most prevalent in 2010; genital herpes in 2021.
- Bacterial STIs decreased, while viral STIs (especially HPV/anogenital warts) increased.
- HIV and anogenital warts saw rapid increases in men; gender differences were noted.
Conclusions:
- Bacterial STIs declined, but viral STIs significantly increased over the decade.
- STI characteristics vary by age and gender, requiring targeted risk group identification.
- Development of tailored prevention policies is crucial for addressing evolving STI landscapes.

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...

01:26Factors Affecting the Risk of Infection
12.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

15.9K
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,...

182
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:
