Snake bites vary tremendously depending on different factors. The person’s height is one of them. Although snakes normally strike in the ankle and calf area, a shorter person might be bitten close to or above the knee because of their height. Similarly, the snake’s size is also important. The larger the snake is, the easier it will be for it to strike higher.
For these reasons, wearing snake protection gaiters is essential as these items can cover your entire calf which is the area that’s most commonly exposed to snake bites.
Other factors that can increase the chances to be bitten above the knee are the angle from which the snake strikes and its position. If you are located at a lower level than the one where the snake is, for example, if you walk down a path and the snake is lurking between some rocks located at your knees’ level, you could get bitten in the upper part of your leg.
