According to World Health Organization (WHO), influenza virus infections cause 3-5
million clinically severe cases and 290-650 thousand deaths per year due to solely
respiratory disease [
[1]
]. Besides its mortality and morbidity, influenza virus infections bring about severe
economic burden on health-care systems. Identifying the prognostic factors and early
recognition of the severe cases can help reduce these undesired outcomes. Older age,
comorbidities (e.g. pulmonary diseases, hearth failure, chronic renal disease, chronic
liver disease and diabetes mellitus), immunosuppressive conditions and pregnancy are
known as classical risk factors for severe disease and mortality [

]. Moreover, usage of some tools and scoring-systems for risk stratification have
emerging importance to determine disease severity and to react quickly before clinical
deterioration.To read this article in full you will need to make a payment
