Snake bites can be a medical emergency, but with proper knowledge and quick action, the risk of serious harm can be significantly reduced. According to the U.S. Centers for Disease Control and Prevention (CDC), approximately 7,000–8,000 people in the United States are bitten by venomous snakes annually. Despite this, fewer than five deaths occur each year, thanks to timely access to emergency care and antivenom.
Globally, however, snakebite envenoming is considered a neglected tropical disease by the World Health Organization (WHO), responsible for over 100,000 deaths annually, particularly in parts of Asia, Sub-Saharan Africa, and Latin America.
While only about 15% of snakes worldwide are venomous, the threat remains real in many regions. In the U.S., four main types of venomous snakes are recognized:
- Rattlesnakes
- Copperheads
- Cottonmouths (Water Moccasins)
- Coral Snakes
These snakes are mostly found in the southern and western states and are usually identified by features such as slit-like pupils, a triangular head, and in the case of pit vipers, heat-sensing pits.
Immediate Actions to Take After a Snake Bite
Your response in the first few minutes following a bite can significantly affect the outcome. Follow these verified emergency steps:
1. Move Away from the Snake
Do not attempt to catch or kill the snake. This increases your risk of further injury and delays necessary care. If safe, take a photo from a distance to assist medical personnel in identifying the species.
2. Stay Calm and Still
According to the Mayo Clinic, staying calm slows the spread of venom by reducing your heart rate. Sit down and keep your movement to a minimum. Avoid panicking or running.
3. Immobilize the Affected Area
Keep the bitten limb below heart level and as still as possible. Use a loose splint if available. This helps slow venom circulation.
4. Remove Tight Items
Gently remove rings, bracelets, or tight clothing near the bite area, as swelling is likely to occur.
5. Seek Medical Attention Immediately
Call 911 or your local emergency number. If you’re in a remote location, begin moving toward help slowly, keeping the affected limb immobilized. Antivenom, available in most hospitals, is highly effective when administered promptly.
What Happens at the Hospital
When you arrive at a medical facility, doctors will:
- Evaluate your symptoms and vital signs.
- Identify the type of snake, if possible.
- Administer antivenom, which neutralizes venom toxins.
- Provide supportive care, such as IV fluids, wound care, and monitoring for complications like infection or allergic reactions.
In the U.S., antivenom is often effective against multiple types of pit viper venom, but treatment depends on the specific species and severity of the bite.
Preventing Snake Bites
The best defense is prevention. Here’s how to reduce your risk of a snake bite according to the American Red Cross and National Park Service:
- Wear boots and long pants when hiking or working outdoors.
- Use a flashlight at night when walking in areas where snakes may be present.
- Do not handle snakes, even if they appear dead.
- Watch where you step, particularly in tall grass, wood piles, and rocky areas.
- Keep campsites clean, as food can attract rodents, which in turn attract snakes.
Recognizing Signs of Venomous Snake Bites
Not all bites inject venom, but signs of a venomous bite may include:
- Severe pain at the bite site
- Swelling and bruising
- Nausea, dizziness, or fainting
- Labored breathing (in severe cases)
Seek emergency care even if symptoms seem mild at first. Venom effects can escalate quickly.
How to Respond in Remote Locations
If you are bitten in a remote area with limited access to emergency services:
- Apply a loose pressure bandage if trained to do so (especially in cases of elapid bites like coral snakes).
- Remain calm and limit exertion.
- Begin moving toward help, ideally with assistance from another person.
- Use emergency communication tools like satellite messengers or flares to signal for help.
Do not delay your attempt to reach medical care.
Final Thoughts: Knowledge Saves Lives
Snake bites are serious but manageable with the right response. The CDC, WHO, and Mayo Clinic all emphasize the importance of immediate medical care, avoiding outdated remedies, and preventive awareness.
Whether you’re an outdoor enthusiast, hiker, or resident in snake-prone areas, knowing what to do in the event of a bite could make all the difference.
