Abstract:
Most estimates of the combined burden and cost of sexually transmitted infections (STIs) in the United States have focused on 8 common STIs with established national surveillance strategies (chlamydia, gonorrhea, syphilis, trichomoniasis, genital herpes, human papillomavirus, and sexually transmitted human immunodeficiency virus and hepatitis B). However, over 30 STIs are primarily sexually transmitted or sexually transmissible. In this article, we review what is known about the burden of "other STIs" in the United States, including those where sexual transmission is not the primary transmission route of infection. Although the combined burden of these other STIs may be substantial, accurately estimating their burden due to sexual transmission is difficult due to diagnostic and surveillance challenges. Developing better estimates will require innovative strategies, such as leveraging existing surveillance systems, partnering with public health and academic researchers outside of the STI field, and developing methodology to estimate the frequency of sexual transmission, particularly for new and emerging STIs.
Insights
Estimating the burden of sexually transmitted infections (STIs) in the US is challenging, as most focus on 8 common STIs. Over 30 other STIs also pose a significant public health concern.
Area of Science:
- Public Health
- Infectious Diseases
- Epidemiology
Background:
- Current estimates of sexually transmitted infection (STI) burden in the US primarily focus on eight common infections.
- Over 30 additional STIs exist, with many not having established national surveillance strategies.
Purpose of the Study:
- To review the current understanding of the burden of
- other STIs
- in the United States.
- To highlight the challenges in estimating the burden of these infections due to sexual transmission.
Main Methods:
- Literature review of existing data on the burden of STIs beyond the commonly tracked eight.
- Analysis of diagnostic and surveillance challenges associated with "other STIs".
Main Results:
- The combined burden of "other STIs" may be substantial, but accurate estimation is hindered by diagnostic and surveillance limitations.
- Sexual transmission is not always the primary route for these "other STIs", complicating burden assessment.
Conclusions:
- Developing more accurate estimates of STI burden requires innovative strategies.
- These strategies include leveraging existing systems, interdisciplinary collaboration, and new methodologies for estimating sexual transmission frequency, especially for emerging STIs.
