What is viral fever

In medical terms, any fever caused as a result of viral infection is a viral fever. However, colloquially, the term 'viral fever' has come to mean a special type of fever that develops and then gets treated without the offending virus being specifically identified. The course and duration of the fever too does not seem to follow any set pattern and is frequently accompanied by, though not always by all of them, generalised bodyache, running nose, cough, shivering, feeling miserable, irritable and depressed.
