5. Fever
A fever could progress once other symptoms are present. Developing a fever is how the immune system usually responds to the presence of a virus or infection within the body. It occurs when the temperature of the body rises above 37℃ and can be an indicator or symptom of other illnesses. A number of complications might arise should the temperature of the body become too high such as hyperpyrexia. Some observable symptoms that verify the presence of a fever include loss of appetite, feeling cold, sluggishness, sweating, and dehydration.
If it is determined that the fever is caused by a viral infection, it can be treated with proper medication and regular fluid intake. However, bringing the fever down might not always be necessary since it is beneficial in combating the infection. A person diagnosed with a fever should have very little contact with other people as well as observe proper hygiene to avoid the spreading of the infection.
