Tens of thousands of people die from snake bites worldwide every year. Lack of treatment and even the wrong medicine mean many of these deaths are preventable.
Snake bites may not strike you as being a major public health problem.
But in some parts of the world they are a daily risk, and can be lethal or life-changing.
Victims often do not get the treatment they need in time, if at all.
In other cases, they are given medicine to treat an injury caused by a different snake.
