The theoretical Oro-Vasculo-Pulmonary route of infection.
Dr Graham Lloyd-Jones - Director of Radiology Masterclass - presents a hypothesis that transmission of the virus to the lungs is mediated by a direct pathway from the mouth to the lungs via blood vessels. Read the full referenced theory here - Oro-vasculo-pulmonary infection route.
The COVID-19 Pathway: A proposed Oral-Vascular-Pulmonary route of SARS-CoV-2 infection and the importance of oral healthcare measures.
The theory has now been published formally, co-authored by experts in the field of oral healthcare: Dr Shervin Molayem (USA); Dr Carla Cruvinel Pontes (SA); and Prof Iain Chapple (UK). The COVID-19 Pathway: A Proposed Oral-Vascular-Pulmonary Route of SARS-CoV-2 Infection and the Importance of Oral Healthcare Measures. J Oral Med and Dent Res. 2(1):1-25. April 20, 2021.
