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.
