An animation describing the hypothetical route of viral transmission from the mouth to the lungs, as first published by Dr Graham Lloyd-Jones FRCR, Director of Radiology Masterclass, at https://www.radiologymasterclass.co.uk/tutorials/covid-19/covid-19-discussion-2 (first published – February 20th, 2021).
The theory has since 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.
