Scientific Data Analysis
A complete catalogue of human-infective RNA viruses
This study updates a critical catalogue of human-infective RNA viruses, identifying 239 species by the end of 2024. It provides detailed metadata including discovery dates, locations, transmission routes, and host ranges. The dataset is invaluable for understanding viral evolution, emerging pathogen risks, and informing global health strategies.
Executive Impact
The updated catalogue of human-infective RNA viruses is a foundational resource for global health, revealing insights into virus discovery trends and epidemiological traits. Its utility spans from informing phylogenetic studies to predicting future pandemic risks, offering a comprehensive view for strategic public health planning.

The 1960s saw the greatest number of new human-infective RNA virus species discovered, with 42 new species identified. This period marks a significant acceleration in virological discovery.
Enterprise Process Flow
The methodology involved extensive literature searches, rigorous validation against ICTV criteria, and expert review to ensure data accuracy and reliability.
| Feature | 2018 Dataset | 2024 Dataset (New) |
|---|---|---|
| Number of Species | 214 | 239 |
| Deltavirus Inclusion | Yes | No (Excluded) |
| Genome Sequence Links | No | Yes |
| Geolocation Data | No | Yes |
| Vector Type Info | No | Yes |
The new dataset significantly expands upon the 2018 version, incorporating 25 additional species, detailed geolocation data, genome sequence links, and updated taxonomic information.
Transmission Levels of Human RNA Viruses
The catalogue categorizes human-infective RNA viruses into four transmissibility levels. A significant majority (62%) are strictly zoonotic (Level 2), highlighting the importance of animal reservoirs. Viruses capable of epidemic spread (Level 4) are a smaller but critical group, with some (Level 4a) having known non-human hosts and others (Level 4b) exclusively infecting humans. Understanding these levels is crucial for pandemic preparedness and public health interventions. For example, the O'nyong-nyong virus (Level 4a) caused large outbreaks and is believed to have an unidentified primate reservoir, underscoring the complexity of zoonotic transmission.
Analysis of transmission levels reveals that 62% of human-infective RNA viruses are strictly zoonotic, emphasizing the need for 'One Health' approaches. This categorization helps prioritize surveillance and intervention strategies for emerging threats.
