 With people spending more time outdoors during summer, it's more possible to come in contact with a rabid animal, and rabies occurs regularly in the state, according to DPH. Since 2019, 54 animals have tested positive for rabies in Delaware. That number is likely higher since only animals that come in contact with people are tested. Susanna Ballman is an epidemiologist for DPH's rabies program. She says there are several visible signs of a rabid animal. The animal being aggressive, appearing confused or drunk-like, walking in circles.
