Infection by rhinovirus: Similarity of clinical signs included in the case definition of influenza IAn/H1N1

Abstract

Our study offers useful information to face future pandemics caused by influenza virus, indicating that differential diagnoses are required in order to not overestimate the importance of the pandemic.

Performance of case definitions used for influenza surveillance among hospitalized patients in a rural area of India

“…Unfortunately, the signs and symptoms of influenza show substantial overlap with those of the infection with other respiratory viruses, such as respiratory syncytial virus, that account for a large proportion of hospitalizations among children aged < 5 years. 29 Since the performances of all the case definitions commonly used to screen for influenza appeared similar, whether the patients considered were aged < 5 years or ≥ 5 years, the development of a common case definition for use in both of these age groups appears reasonable.…”
