Answer :
Answer: Fever is a common symptom of illness. The Centers for Disease Control and Prevention (CDC) defines fever as a temperature above 100.4° F, though children often run higher fevers than adults.
Many types of infection can cause fever, as your body will increase temperature to effectively fight off the virus or bacteria causing the infection. These fevers will usually resolve themselves as your body works to get rid of the foreign invader.
Explanation:
Fever is one of the common symptoms of different illnesses and is also a defense mechanism of the body. A temperature above 100.4° F is considered as fever.
Fever can be caused due to:
1. The rise in the skin temperature is generally due to the infection from bacteria or viruses that can result in the flu, cold, or certain viral diseases. The fever can be an indication of any infection or inflammation in any part of the body.
2. The activities like exercising can also lead to an increase the body temperature. The contraction of muscles releases 20% energy and the rest 80% is converted into heat energy. The heat is then circulated to different parts of the body, causing an increase in the temperature.
3. The rise in the temperature can be measured by the thermometer. It is a device that measures body temperature either digitally or traditionally.
Thus, the cause of fever can be a defense mechanism, exercise, and infection from the pathogen.
