Fever and human race



Fever is a condition of having an increased body temperature above than a normal range. Though there is no single one set point for human normal temperature, but still from 37 to 38 degree is considered normal.

Why do we get fever?
Fever is said to occur when our body is trying to kill a virus or bacteria in our body which is causing infection.  Normally these viruses and bacteria grow well when our body has a normal temperature, but if body temperature is slightly increased, this virus or bacteria is killed. Fever is also said to speed up our immune system.

Fever can be life threatening if keeps on increases and it can cause seizures. Viruses and infections that causes fever  includes viral, bacterial, and parasitic infections—such as influenza, the common cold, meningitis, urinary tract infections, appendicitis, Covid-19 and malaria.

The four types of fever
There are five patterns: intermittent, remittent, continuous or sustained, hectic, and relapsing. With intermittent fever, the temperature is elevated but falls to normal (37.2°C or below) each day, while in a remittent fever the temperature falls each day but not to normal.


Fever – history in human race
Fever is one of the oldest symptoms of illness in human body. It is also one of the most common reasons for medical consultations around the world. A number of types of fever were known as early as 460 BC  we read about  Hippocrates practicing medicine including study on fever also  due to malaria. It also became clear around this time that fever was a symptom of disease rather than a disease in and of itself.

Fever dates back as far as human civilization itself. One of the first diseases known to mankind.  Many ancient civilizations having wide knowledge of human anatomy and physiology , saw fever only as a work of evil spirits.Some ancient physicians saw it beneficial for human health.

Humans have worked on it and have fought against fever through ages and still the researches are going on. Though much has been discovered, so much is still there to find out.
