Is an insect bite a wound or injury?

An insect bite would be considered a wound, which is another term for a minor injury.

However, if the bite caused an infection or triggered an allergic reaction, that would more than likely upgrade the situation to an injury. And if the bite happened to be the vector for an insect-borne disease (such as West Nile virus or malaria) you might even upgrade it further by labeling it the entry point of a chronic condition.
