Lyme borreliosis surveillance and climate data for Poland, 2009–2024: harmonised voivodeship-quarter panel and analytical code

A planetary-health framework for interpreting vector-borne disease notifications, tested with Lyme borreliosis in Poland, 2009–2024" (The Lancet Planetary Health). The core dataset is a voivodeship-quarter panel covering all 16 Polish administrative regions across 16 consecutive years (1,024 voivodeship-quarter observations; 259,003 reported Lyme borreliosis cases).

Each row combines quarterly case counts, annual case counts, incidence per 100,000 population, hospitalisation counts, and hospitalisation proportion, sourced from the National Institute of Public Health NIH – National Research Institute (NIZP-PZH-PIB) epidemiological bulletins, with quarterly climate variables — mean air temperature, total cloud cover, relative humidity, wind speed, total precipitation, days with snowfall, and maximum daily precipitation — aggregated from two IMGW-PIB station networks (klimat: 28 stations across 12 voivodeships; opad: 1,135 stations across all 16 voivodeships).
