Various diseases and infections (bacterial, viral, parasitic) exhibit fever as a symptom. Fever is nothing but elevated body temperature. The normal body temperature, when measured orally can be 98. 2±1. 3 ? F or 36. 8±0. 7 ? C. Sweating is a way of maintaining normal body temperature. Brain, sweat glands in the skin, blood vessels and hormones play an important role in maintaining normal body temperature. Enzymes and hormones in the body cannot work properly if the temperature of the body rises above or drops below the normal range. Persistent high fever can prove to be fatal.
Body raises its temperature to kill the pathogens. This is an adaptive mechanism which helps accelerate the immune system. Different Types of Fever Fever can be classified according to the symptoms associated, its cause and its pattern. Fever can be low-grade (body temperature less than 101 ? F) or high grade (temp. over 104 ? F). The pattern of fever often helps diagnose the disease. Here are fever types according to the typical pattern of the fever. » Continuous Fever The patient notices higher than normal body temperature throughout the day but he/she does not notice severe fluctuations in body temperature.
Small variation of about 1 ? C may be noticed within 24 hours. This type of continuous fever is noticed in patients who have urinary tract infection, typhus, lobar pneumonia or brucellosis. When children and adults suffer from typhoid fever, they suffer from consistently elevated body temperature (sustained fever) for a prolonged period of time. This fever subsides only after taking medication. » Remittent Fever When the person having fever experiences temperature fluctuations, more than 1 ? C during 24 hours, it is called remittent fever.
For example, patients suffering from infective endocarditis may experience this type of fever. » Intermittent Fever The patient experiences fever for a certain period of time. Then again, his/her body attains normal temperature. This type of fever is observed during malaria, black-fever, or septicemia. Intermittent fever is termed as quotidian fever when it is experienced for 24 hours. It is referred to as tertian fever when it remains for 48 hours. Patients of malaria may experience quotidian or tertian type of fever pattern.
Patients suffering from plasmodium malariae suffer from fever which exhibits 72 hour periodicity. This type of fever is known as quartan fever. A body temperature that exhibits a typical pattern of ‘highs and lows’ is also known as episodic fever. » Relapsing Fever When fever reappears after a certain period of time, it is called relapsing fever. Not only once but fever may reappear a number of times. Those who have a weak immune system may have to face this problem. » Pel-Ebstein Fever Some doctors don’t accept this as a type of fever. Some don’t agree that this type of pattern exists.
This type of fever is seen in patients of Hodgkin’s lymphoma, a cancer of white blood cells. The patients suffer from high fever for one week and low fever for the next week. This was about the patterns of fever. The type of fever and associated symptoms may vary according to the underlying cause of the fever.
