Summary
Gonorrhea prevalence in Brazil is estimated below 1% for women and men. Limited data exists for men and vulnerable populations, highlighting a need for more research on this sexually transmitted infection.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- Gonorrhea is not a notifiable disease in Brazil.
- National health information systems do not track gonorrhea cases or prevalence.
- This lack of data hinders understanding of the disease burden.
Purpose of the Study:
- To estimate the prevalence of gonorrhea in Brazil between 2000 and 2020.
- To analyze trends in gonorrhea prevalence over two decades.
- To identify data gaps in gonorrhea surveillance.
Main Methods:
- Compiled published data on gonorrhea prevalence from 2000-2020.
- Included studies with sample sizes of 50+ and confirmed Neisseria gonorrhoeae infection.
- Utilized Spectrum-STI statistical modeling for trend analysis.
Main Results:
- Analyzed 45 studies with 59 prevalence data points.
- Estimated 2020 urogenital gonorrhea prevalence: 0.63% in women (15-49) and 0.70% in men.
- Observed a decreasing trend from 2000 to 2020 for both sexes.
Conclusions:
- Overall genitourinary gonorrhea prevalence in Brazil is estimated below 1%.
- Significant data limitations exist for gonorrhea prevalence in men.
- Further research is needed on gonorrhea in populations with increased STI vulnerability.

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.

01:26Sexually 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...

01:26Factors Affecting the Risk of Infection

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...

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
