📖What is Snake Bite?
Snake bite is an injury caused by the bite of a snake, which becomes a medical emergency when the snake is venomous, as the injected venom can cause a range of harmful effects on the blood, nervous system, muscles, or tissue at the bite site. Venom composition varies significantly between snake species, with some causing predominantly local tissue damage and swelling, others causing disrupted blood clotting and internal bleeding, and others causing paralysis by blocking nerve signal transmission to muscles, including those needed for breathing. Snake bites are a significant public health concern in rural and agricultural areas of many countries, where access to timely medical care and antivenom can be limited. Prompt identification of whether the snake was venomous and rapid transport to a facility with antivenom available are critical to outcome.
