Analysing risk factors of lumph skin disease by geographical information system (GIS) in Turkey
Ince, Omer Baris
Lumpy skin disease (LSD) is caused by the virus of the same name and has major economic impacts on cattle raising. In Turkey, frequent cases of cattle LSD have been recorded over the last years. The aim of the study was to analyze potential LSD risk factors and provide guidelines for controlling disease spread. The study comprised cross-sectional and retrospective studies with active disease follow-up and semi-structured interviews (SSI) from August 2013 to December 2014 in Turkey. Potential LSD risk factors were evaluated based on environmental conditions and provincial demographic and epidemiological data. Of the total of 562 observed animals, 27.22% and 2.67% cattle were sick and dead due to LSD, respectively. The morbidity rate was 26.04% in mix and 38.18% in local breeds. Animal-level prevalence among age, sex and vaccination status were significantly (P<0.05). It was more serious in younger animals and females and during drier conditions. A trend of seasonality was observed in LSD occurrence. Significant risk factors affecting the prevalence of LSD were proximity to the southern border of Turkey, animal movement, and animal markets. In this process; geographical query, analysis and thematic map production were performed by GIS.
