Summary
Lyme disease cases in Poland increased by 2.4% in 2019, with a shift in incidence to the fourth quarter. Diagnosis challenges hinder definitive trend analysis despite rising tick-borne disease risk.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Lyme disease, caused by Borrelia spirochetes, is Poland's most common tick-borne illness.
- Poland is an endemic area for Lyme disease, with increasing risks due to environmental and climate factors.
- Rising tick populations heighten the risk of Lyme disease transmission.
Purpose of the Study:
- To analyze the epidemiological situation of Lyme disease in Poland in 2019.
- To compare the 2019 Lyme disease data with the preceding year (2018).
Main Methods:
- Analysis of epidemiological data on Lyme disease in Poland for 2019.
- Utilized data from voivodeship sanitary-epidemiological stations reported to NIPH NIH - NRI.
- Referenced the bulletin "Infectious diseases and poisoning in Poland in 2019."
Main Results:
- 20,630 Lyme disease cases and 1,701 hospitalizations were registered in 2019.
- A 2.4% increase in total cases compared to 2018, with a seasonal shift towards Q4.
- Podlaskie voivodeship reported the highest incidence (107.7/100,000), a consistent trend.
Conclusions:
- Diagnostic difficulties complicate definitive epidemiological trend assessment in Poland.
- Increased incidence may stem from more infected ticks and improved physician awareness.
- Ongoing monitoring is crucial for understanding Lyme disease dynamics in endemic regions.

Bacterial Phylum Spirochaetes
172
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...
