Snake Bite
On average, about 7,000 people in the United States are bitten by snakes each year.


On average, about 7,000 people in the United States are bitten by snakes each year. In Texas, 1 to 2 people die each year as a result of snakebites, and upwards of 150 rattlesnake bites occur annually.

Meanwhile, people in Arizona experience about 150 to 200 rattlesnake bites each year. However, Arizona averages less than 1 death per year from venomous snake bites. The last person to die from a venomous snake bite passed away in 2007.

Fortunately, most people that grow up in these areas know what to do when faced with venomous snakes. Specifically, they know where snakes like to hide and to maintain a safe distance if they stumble upon one. Unfortunately, venomous snakes and humans have some accidental contact, sometimes leading to bites. Yet, modern medicine has reduced the number of deaths.  

What Should You Do If Bitten by a Venomous Snake?

Getting medical attention as soon as possible after a snake bite helps to avoid complications.


People living in states with a high density of venomous snakes, like Arizona and Texas, need to know what to do following a venomous snake bite. Follow these steps to get the best outcomes.

  1. Get medical attention as soon as possible by calling the local emergency services.
  2. If possible, take a picture of the snake from a safe distance. Do not pursue the snake to take a picture. Knowing the type of snake can make a difference in treatment.
  3. Try to stay calm.
  4. Remove any jewelry like rings that may become stuck on a finger once swelling starts.
  5. Wash the area around the bite and cover it with a clean bandage.

Knowing what to do in this event is important, but you also need to know a few things not to do. For example:

  1. Do not try to suck the venom from the wound.
  2. Do not try to trap the snake for identification.
  3. Do not rely on alternative medicine as a primary treatment.
  4. Do not tie a tourniquet around a limb.
  5. Do not delay treatment.

Acting properly in the face of this medical emergency can help a person survive the incident with as few complications as possible.

Between Texas vs. Arizona, the latter has more venomous snakes. However, people in both states need to be respectful of the presence of the potentially dangerous wildlife that lives in their area. Knowing what venomous snakes live in an area and how to properly respond to their presence can reduce the likelihood of a medical emergency.
