A Community-Directed Integrated Strongyloides Control Program in Queensland, Australia

Area of Science:

• Infectious Diseases
• Tropical Medicine
• Public Health

Background:

• Strongyloidiasis is a significant health issue in remote Aboriginal communities.
• A high prevalence of strongyloidiasis (12% fecal, 30% serology) was identified in Woorabinda in 2004, leading to morbidity and mortality.
• Previous interventions lacked community direction and comprehensive data capture.

Purpose of the Study:

• To describe a community-directed intervention to address strongyloidiasis in Woorabinda.
• To highlight the critical role of local Aboriginal leadership and community engagement in a mass drug administration (MDA) program.
• To disseminate key success factors from a co-designed 'treat-and-test' MDA for Strongyloides stercoralis.

Main Methods:

• A two-phase community-directed intervention was implemented in partnership with the Community Health Service.
• Phase 1 involved a 'treat-and-test' MDA using oral ivermectin for all residents, with repeat doses for positive serology.
• Community-developed health promotion materials targeted local environmental health concerns; 92% participation was achieved.

Main Results:

• The prevalence of strongyloidiasis was 16.6% during the intervention.
• A cure rate of 79.8% was achieved after two doses of ivermectin, based on serology.
• The program demonstrated the effectiveness of community leadership and high participation in controlling S. stercoralis.

Conclusions:

• Community-directed interventions with strong local leadership are crucial for controlling infectious diseases like strongyloidiasis.
• High community engagement and co-design are vital for successful public health programs in Indigenous communities.
• This initiative represents a significant advancement in controlling S. stercoralis in Australia, emphasizing Indigenous-led health solutions.
