Viral fever is an acute viral infection that occurs due to seasonal changes and infection in the environment, especially in the monsoon season. It is generally characterized by an elevation in the normal body temperature along with cold and flu. Usually, it is not a disease in itself but an effect of viral infection. Viral fever sometimes may remain undiagnosed until it makes headway to the later stages.

Viral fever is a collective term given to a wide range of viral infections in people with low immunity. Getting a fever is a sign that your body is trying to fight the bacteria or virus that has caused the infection. It is common among children and older people due to their lower immunity.
