Each year in the United States, more than 350,000 dog bite victims are seen in emergency rooms (totaling about 1% of all ER visits) and approximately 750,000 bite victims receive medical attention. In addition, dog and other animal bites are prone to infection, leading to complications and longer healing times. In this clinical study, medical staff found that when compared with leaving wounds open, negative pressure wound therapy reduced the infection rate and shortened recovery time for dog bite victims.
