An Overview of Viral Respiratory Infections

Abstract

Background: Various viruses and bacteria are involved in the incidence of respiratory tract infections(RTIs), and viruses account for the majority of RTIs. Given the high economic and therapeutic burdenof RTIs, the current review aimed to present a brief but comprehensive overview of the most importantviral etiologies of RTIs along with their complications, manifestations, and transmission routes. Acomprehensive literature search was performed in electronic databases including Google Scholar,Scopus, PubMed, and Web of Science to find articles related to the scope of this research, published inEnglish. Eligible studies providing evidence on viral respiratory tract infections, their clinicalcomplications, symptoms, and causes were included in this review.

Conclusion: Considering the diversity and prevalence of viral RTIs and the economic and therapeuticburden imposed on health systems, it is necessary to raise public awareness about their transmissionmethods and preventive measures to control and manage these infections.
