A fever is usually caused by infections from viruses (such as a cold or the flu) or bacteria (such as strep throat or some ear infections). The fever itself is not the disease, only a sign that the body’s defenses are trying to fight an infection.
Fever is not an illness, rather, it is a symptom of sickness and is usually a positive sign that the body is fighting infection. However, a fever can make your child uncomfortable and in some cases it can trigger a febrile convulsion.
