What topics and trends defined most-cited Vector-borne infectious diseases research in the Class of 2026?
Research in vector-borne infectious diseases is transitioning from broad Lyme disease surveillance toward spatial epidemiology and multi-pathogen risk assessment. Species distribution modeling and tick-borne encephalitis saw substantial gains in top-cited literature, alongside rising focus on vector ticks like Ixodes ricinus and emerging hemotropic pathogens.

Topic trends
Dominant research themes and year-over-year shifts in Vector-borne infectious diseases
What Topics Define the Class of 2026?
The Class of 2026 ranking for vector-borne infectious diseases highlights a heavily concentrated research ecosystem centered on tick-borne pathogen transmission, vector ecology, and spatial epidemiology. Lyme disease remains the focal clinical narrative, appearing in 14% of top-cited publications, closely paired with its primary etiological agent Borrelia burgdorferi (8%) and related Borrelia species. Vector biology research is overwhelmingly anchor-driven by Ixodes ricinus (10%), the principal hard tick vector in Europe, alongside expanding investigation into Rhipicephalus sanguineus (6%), reflecting heightened interest in canine and human vector-host dynamics. Beyond classical spirochete surveillance, the field demonstrates a pronounced shift toward predictive ecology and multi-pathogen profiling. Species distribution modeling (8%) emerges as a core computational tool, enabling researchers to map vector habitat suitability and climate-driven range shifts. Concurrently, viral and parasitic co-infections command significant attention, led by tick-borne encephalitis (8%), the intraerythrocytic parasite Babesia microti (6%), and emerging hemoplasmas (6%). Together, these dominant clusters underscore an integrated One Health paradigm that bridges molecular diagnostics, ecological forecasting, and vector management to mitigate rising tick-borne disease burdens globally.

How Did Topics Shift from the Class of 2025 to the Class of 2026?
Comparison between the Class of 2025 and Class of 2026 cohorts reveals a marked evolution from descriptive Lyme disease reporting toward quantitative vector dynamics and emerging viral/bacterial co-pathogens. While Lyme disease (declining from 22% to 14% normalized frequency) and Borrelia burgdorferi (dropping from 20% to 8%) previously dominated the top-cited literature, the 2026 cohort reflects a rebalancing of research priorities toward a broader spectrum of tick-borne threats and analytical methodologies. The most prominent growth is led by tick-borne encephalitis, which experienced a four-fold rise in high-impact literature representation (2% to 8%), alongside a three-fold increase for Rhipicephalus sanguineus (2% to 6%). Species distribution modeling doubled in frequency (4% to 8%), highlighting growing reliance on geospatial modeling to predict vector proliferation. Furthermore, novel detection of hemoplasmas (rising from 0% to 6%) and emerging pathogens such as severe fever with thrombocytopenia syndrome virus (SFTSV), Ehrlichia canis, and Haemaphysalis longicornis underscores an expanding surveillance frontier. Conversely, broad observational concepts like general geographic range expansion experienced relative decline. This trajectory signals a field maturing from generalized risk awareness to precise, model-driven risk prediction and targeted pathogen intervention.

Methodology
PRI identifies high-impact research using a transparent, topic-agnostic framework applied consistently across scientific domains. Bibliographic records are drawn from OpenAlex, including publication dates, citation relationships, and document types.
This ranking covers the Class of 2026 cohort: journal articles published in 2024. Reviews and other non-article document types are excluded to ensure comparability.
Research impact is quantified with an 18-month post-publication citation window—the number of citing works published within 18 months of each paper's publication date. This metric captures early impact while controlling for publication age.
An LLM-based relevance classifier then reviews each candidate's title and abstract to confirm substantive alignment with the target domain. Only papers classified as relevant appear in the final ranking.
