Abstrakt: In India, tick-borne diseases are prevalent in many states due to the presence of tick vectors. However, information on disease-causing ticks from domestic animals and the associated risk factors for residents living in the disease-endemic area is lacking. Therefore, we conducted this study to identify ixodid ticks in goats and human risk factors in three villages of the Wayanad district of Kerala. We examined 202 goats and collected 741 ticks, of which 69.8% were ticks belonging to the genus Haemaphysalis. The maximum number of ticks was collected from Thirunelli (81.3%), followed by Noolpuzha (76.27%) and Pulpally (45.6%). Overall, H. bispinosa Neumann, 1897 (54.6%), was the most common species, followed by H. turturis Nuttall and Warburton, 1915 (38.0%), H. spinigera Neumann, 1897 (5.4%), and H. intermedia Warburton and Nuttall, 1909 (1.8%). We included 428 participants (men and women) in this study. The average age of the respondents was 43 years. We found significant associations between accessing the forest for cattle grazing and other activities and tick-borne diseases (χ 2  = 9.5, p = 0.002), between workers who were bitten by ticks and tick-borne diseases (χ 2  = 3.8, p = 0.05), and between number of tick bites per day > 6 and tick-borne diseases (χ 2  = 12.1, p = 0.001). The high frequency of Haemaphysalis spp. found in goats highlighted the risk of tick exposure and tick-borne diseases, such as Kyasanur forest disease in humans, and the need for the development and implementation of effective measures to control ticks.
