'''Influenza''', commonly known as '''flu''', is an [[infectious disease]] of birds and [[mammal]]s caused by  [[RNA virus]]es of the biological family [[Orthomyxoviridae]] (the influenza viruses). In humans, common symptoms of influenza infection are [[fever]], [[pharyngitis|sore throat]], [[myalgia|muscle pains]], severe [[headache]], [[cough]]ing, [[fatigue (medical)|weakness]] and [[malaise|general discomfort]].

Overview

Laboratory Findimgs

The available laboratory tests for influenza continue to improve. The United States Centers for Disease Control and Prevention (CDC) maintains an up-to-date summary of available laboratory tests.[1] According to the CDC, rapid diagnostic tests have a sensitivity of 70–75% and specificity of 90–95% when compared with viral culture. These tests may be especially useful during the influenza season (prevalence=25%) but in the absence of a local outbreak, or peri-influenza season (prevalence=10%).
