    "abstract": "Dengue fever (DF), transmitted by \nThis study analysed the impact of climatic factors on DF incidence in Kenya using a Zero-Inflated Poisson (ZIP) model.\nThe study focused on DF cases in Kenya from 2019 to 2021.\nA ZIP model was applied to monthly dengue case data and associated climatic variables, such as temperature, rainfall, and humidity. The model addresses over-dispersion and excess zeros in the data, providing a more accurate depiction of DF dynamics.\nThe ZIP model revealed significant associations between climatic variables and DF incidence. Humidity (\u03b2 = 0.0578, standard error [s.e.] = 0.0024, \nThe results suggest that higher humidity and temperature favor dengue transmission, while heavy rainfall may disrupt mosquito breeding, reducing cases. These findings provide a basis for targeted public health interventions.\nThis study enhances understanding of DF-climate interactions in Kenya, supporting the application of ZIP modelling for improved disease surveillance and control strategies.",
