ISSTDR
The International Society for Sexually Transmitted Diseases Research, established in 1977, organizes bi-annual scientific meetings covering the entire range of biomedical, behavioral and social sciences involving all STDs, including HIV infection.
STI Team Maastricht
Our STI research group of Maastricht University Medical Centre (MUMC+) and Regional Public Health Service (GGD Zuid-Limburg) within research school Care and Public Health Research Institute (CAPHRI), under the name "STI team Maastricht" has acquired a leading international position in the field STI research. This has been achieved by expanding a number of core qualities that are present within the group:
- A unique bridge between public health (GGD) - with a large STI clinic (> 8000 patients per year) with systematic registration - and innovative medical microbiology with the most modern molecular techniques to optimize STI control.
- Methodological diversity (including classical epidemiology, key population approach, network methodology, geographical information systems, e-health approach, web-based respondent-driven sampling).
- A large biobank with over 100,000 samples.
- Cooperation on the complete cascade of care and cure: including collaboration with behavioral sciences (including in the field of stigma and intervention mapping strategies) to realize effective behavioral interventions within STI control.
In the future, the international position will be continued and strengthened. More attention will be paid to international cooperation and expansion of the network in order to increase opportunities in future grant applications and to strengthen the impact of the research output and thus the position of the MUMC +/GGD Zuid-Limburg tandem.

Additionally, she wants to improve accessibility to the preventive sexual healthcare services for the home-based sex workers. She has mainly conducted qualitative research.
Dieuwertje Horsten, PhD-student

(Jonathan Vos Photography)
Dieuwertje Horsten is a sexual health physician and PhD candidate and researching the public health response to the sexually transmitted infection gonorrhea.
Research summary
Gonorrhea poses an increasing challenge to public health concern due to its rising incidence and growing resistance to antibiotics. Dieuwertje’s doctoral research focuses on improving the control and management of gonorrhea within the public health system. A key component of the study is the role of symptoms in the detection of gonorrhea: how many people with gonorrhea present with symptoms, and can those symptoms support more targeted STI testing?
Another important aspect of the project is the evaluation of so-called "presumptive” treatment — administering antibiotics before test results confirm a gonorrhea diagnosis. The research assesses the effectiveness and efficiency of this approach.
In addition to the clinical perspective, her research also explores the broader social impact. Through interviews with young people under the age of 25, she investigates their experiences with gonorrhea, perceptions of risk, and views on prevention. This project aims to provide valuable insights that contribute to a more effective and evidence-based approach to gonorrhea control within public health.
Objective
To gain a deeper understanding of and improve the public health approach to gonorrhea infections, with a focus on clinical presentation, the effectiveness of testing and treatment strategies, and the needs of affected populations.
