Impatiens necrotic spot virus, the pathogen most often detected in begonias, causes many different symptoms including dead areas on stems, mottled or mosaic patterns, lines, ringspots, or yellow, white or brown spots. The closely related tomato spotted wilt virus also causes varying symptoms. Both viruses are transmitted by thrips and by propagating infected plants.
