Competition to Explain Stable Prevalence of Seasonal Viral Respiratory Infections in Temperate Climates

The prevalence of seasonal viral respiratory infections in temperate climates is relatively stable, but individual viruses vary. This phenomenon is not explained via the conventional view of influenza seasonality which is still incomplete. The viral-flow theory, an outsider theory about the seasonality of influenza, where insects buffer viruses, is able to explain the stable prevalence of viral respiratory infections. Alternative hypotheses to explain this phenomenon are discussed.
