How Dangerous Are Sharks?

People are naturally frightened of sharks, especially as a result of the media and movies. But in fact, even open water swimmers have more things to worry about. For example, humans are nearly 40 times as likely to be killed by dogs than killed by a shark.

However, the National Safety Council, the Disease Control & Prevention and the International Shark Attack File provided the following information about disease and accidental causes of deaths and the risk during one’s lifetime in the United States:
