Snake Bite: Causes, Effects, and Prevention
Introduction
Snakes are an important part of our ecosystem. They control rodent populations and maintain ecological balance. Yet, of the 3,000+ snake species worldwide, about 600 are venomous. According to the World Health Organization, snake bites cause 81,000โ138,000 deaths each year, with India accounting for nearly 50% of global fatalities. In states like Kerala, where Iโm located, encounters are more common due to dense vegetation, agriculture, and monsoon flooding. Understanding snake bites is crucial for survival and public health.
Types of Snakes and Venom
Snake bites are broadly divided into two categories: venomous and non-venomous. Non-venomous bites cause pain, swelling, and risk of infection, but are not life-threatening. Venomous bites are far more dangerous.
Indiaโs โBig Fourโ venomous snakes are responsible for most deaths:
1. Common Krait โ Nocturnal, often bites people sleeping on the floor. Its venom is neurotoxic, causing paralysis.
2. Indian Cobra โ Neurotoxic venom leads to respiratory failure. Recognizable by its hood.
3. Russellโs Viper โ Hemotoxic venom causes bleeding, kidney failure, and severe pain.
4. Saw-sca
