What symptom is associated with a snake bite?

The presence of a single or double fang mark is a key symptom associated with a snake bite. This characteristic feature helps identify the type of bite received, as venomous snakes typically leave distinct fang patterns that can vary between species. Recognizing fang marks is crucial for providing appropriate treatment and can guide medical professionals in determining the necessary antivenom or interventions needed based on the bite’s severity and the snake's potential to cause harm.

While other symptoms like persistent coughing, blurry vision, and rapid heartbeat may occur in some cases of snake bites, they are not as definitive for identification as fang marks. Fang marks provide immediate visual evidence of a snake bite, whereas the other symptoms can be caused by various medical conditions, complicating the diagnosis.
