A cough detection device including: an acoustic feature extractor that extracts at least one acoustic feature from acoustic data output by a microphone array according to a sound received; a first identifier that performs identification of the sound based on the at least one acoustic feature to determine whether the sound is a cough sound; a direction estimator that estimates an arrival direction of the sound from the acoustic data; an image selector that selects, from first image data indicating an image obtained by capturing a scene in which the sound occurs, second image data indicating an area corresponding to the arrival direction estimated; and a second identifier that performs identification of the image based on the second image data to determine whether a coughing action is shown in the image.
