This study maps the rapidly expanding field of long COVID (LC) research, identifying key topics and research players. Findings reveal a growing, interconnected, multidisciplinary domain with increasing focus on neurological and fatigue symptoms.
Area of Science:
- Bibliometrics
- Medical Research
- Public Health
Background:
- Long COVID (LC) presents complex post-infection symptoms following SARS-CoV-2.
- Understanding the burgeoning LC research landscape is crucial for addressing its ramifications.
Approach:
- A bibliometric analysis of 5,243 articles from PubMed and Web of Science was conducted.
- A 13-topic Concept Grid visualized topic clusters and research connections.
- Analysis included disciplinary concentrations, research players (countries, institutions, authors), and temporal trends.
Key Points:
- The LC research domain is rapidly expanding and highly multidisciplinary.
- Strong interconnections exist within LC research, alongside distinct disciplinary concentrations.
- Recent trends show increased focus on psychological, neurodegenerative, fatigue, and pulmonary symptoms.
Conclusions:
- This study provides a comprehensive overview of the LC research landscape.
- The findings enhance accessibility to LC knowledge and highlight key research trajectories.
- Future research should consider the identified trends in symptomology and disciplinary focus.
