- Chikungunya virus (CHIKV) has evolved from a localized pathogen to a global pandemic threat due to climate change and urbanization.
- A 20-year bibliometric analysis (2004-2025) examined 8,125 publications to assess CHIKV research trends and pandemic preparedness.
- Annual publications surged 7-fold after 2013, peaking during epidemics like the Caribbean (2013-2014) and Réunion (2024).
- Key research hubs included the USA, Brazil, France, and India, forming distinct regional collaboration networks.
- Thematic clusters highlighted rising priorities: vaccine development (+7.1% growth, e.g., VLA1553) and climate-driven transmission ('environmental health' post-2022).
- Persistent gaps included diagnostic overlap with dengue/Zika and reactive outbreak responses (emergency-focused keywords declined from 15.5% to 7.2%).
- International collaborations favored high-income and endemic nations, showing limited equity.
- Critical weaknesses remain in equitable collaboration, climate-adaptive surveillance, and integrated interventions.
- Recommendations include predictive modeling, rapid-response vaccine platforms, and embedding CHIKV preparedness in climate-resilient health policies.
