Background: Chikungunya and dengue represent a significant public health challenge in tropical and subtropical regions. Their symptoms are often mistaken for those of malaria, leading to diagnostic errors. In Burkina Faso, recent outbreaks, 2023, have been reported. Control efforts rely on prevention, early diagnosis, and proper management by healthcare workers. However, gaps in their knowledge, attitudes, and practices can hinder effective case management. A study in Bobo-Dioulasso assesses these knowledge, attitudes, and practices to improve response strategies and guide public health policies.

Methods: A cross-sectional study was conducted in public and private hospitals in Bobo-Dioulasso and its surrounding areas from August 2024 to February 2025. A pre-tested structured questionnaire, including a series of questions on these diseases, was used to assess healthcare workers' knowledge of dengue and chikungunya (causal agent, modes of transmission, and symptoms) and their management practices: diagnosis, preventive measures, and treatment. Individual interviews were conducted with study participants, including doctors, nurses, midwives, laboratory technicians, and medical assistants.

Results: A survey of 210 healthcare workers in Bobo-Dioulasso revealed that 68.57% had a high level of knowledge about dengue, linked to profession and experience, while 55.86% showed good knowledge of chikungunya, primarily tied to profession. Over 90% knew both diseases are mosquito-borne, but awareness of chikungunya (69.04%) lagged behind dengue (100%). Diagnostic methods were correctly identified by 75.24% for dengue and 62.76% for chikungunya, though some errors (e.g., blood smears) persisted. Prevention measures were better understood for dengue (64.29%) than chikungunya (41.38%). Case management knowledge was higher for dengue (83.33%) compared to chikungunya (57.24%). Overall, healthcare workers demonstrated stronger knowledge and practices for dengue than chikungunya. However, some healthcare workers still require training, despite the 2023 outbreaks, particularly those with a low level of knowledge. Additionally, to improve case management, staff have expressed the need for ongoing training and refresher courses to strengthen their acquired knowledge.

Conclusion: All healthcare workers demonstrated better knowledge and practices for dengue compared to chikungunya in Bobo-Dioulasso and its surrounding areas. However, some still have a low level of knowledge, highlighting the need to intensify training efforts.
