The dangerous shark is just as rare as the nonaggressive shark. Obviously there are species which - simply due to their size - should only be approached with great caution, for body size is a problem when it comes to dealing with sharks.
A fever is a rise in body temperature. It's usually a sign of infection. The fever itself is generally harmless and probably helpful. Fevers usually don't need treatment. The average body temperature is 98.6 F (37 C).But normal body temperature can range between 97 (36.1) and 99 (37.2) or more.Your body temperature can vary depending on how active you are or the time of day.

A fever, also referred to as pyrexia, is an elevation in the body temperature above the norm. This is broadly defined as oral temperature reading above 37.5 degrees Celsius (99 degrees Farenheit) and a core body temperature (rectally) above 38 degrees Celsius (100.4 degrees Farenheit).Variations in temperature may occur depending on where the measurement is taken (oral, rectal, axilla). In infants younger than 8 weeks, a body temperature greater than 38.3 degree Celsius/101 degrees Farenheit should be considered as a high fever and requires prompt immediate medical attention.
