Transmission of respiratory viruses using a new viral challenge model

Author(s): Emma Wilson

Interest in how respiratory viruses spread has been rekindled by the recent advent of Coronavirus Disease- 2019 (COVID-19), as well as the morbidity and mortality that it causes. Understanding the factors that influence transmission is essential for developing non-pharmaceutical therapies and halting spread. The Respiratory Syncytial Viruses (RSV-A and RSV-B), influenza A and B (Flu), Coronaviruses (CoV), Adenoviruses (AdV), Parainfluenza Viruses (PIV), Human Meta Pneumovirus (HMPV), and bocavirus are among the other common causes of Acute Respiratory Virus Infection (ARI), despite the current focus on infections caused by SARS-CoV-2. 1,2 ARIs have significant negative health and financial effects, resulting in 110 million primary care visits, 20 million missed school and work days, and an approximate 40 billion dollar yearly economic cost in the United States alone.
