Viral Fever is a general term for an elevated body temperature caused by a viral infection. It occurs when a virus enters the body and triggers an immune response, leading to fever. This common condition can affect people of all ages worldwide and is a symptom of numerous viral illnesses.
The understanding of fever as a symptom of disease has existed for centuries. The scientific distinction between viral and bacterial causes of fever evolved significantly in the late 19th and 20th centuries with the development of virology. This led to the recognition that microscopic, filterable agents—viruses—were responsible for many febrile illnesses previously of unknown origin.
Viral fevers typically spread through person-to-person contact, mainly via respiratory droplets expelled when an infected person coughs, sneezes, or talks. These droplets can be inhaled by others or contaminate surfaces. Infection can also occur by touching contaminated surfaces and then touching one's face. Some viruses may also spread through direct contact with infected bodily fluids.
