Dear Editor,I read with interest the suggestions proposed by Lucaciu et al. in their recent article. However, the authors make inaccurate references to the established transmission routes of SARS-CoV-2. The authors state that the novel coronavirus is spread via aerosols and the faecal-oral route, in spite of a largely undeveloped evidence-base in support of these pathways. In their most recent scientific brief, the World Health Organisation suggest heightening infection prevention and control measures around contact and respiratory droplet transmission. Indeed, aerosol-generating procedures (AGPs) are implied in facilitating airborne transmission but limited evidence is available to support this for SARS-CoV-2. There is an urgent need to develop the evidence-base for the risk associated with AGPs, particularly when planning the return to routine dental practice.The authors imply confirmation of the faecal-oral route and reference a paper by Meng and colleagues however this seems to have been misinterpreted. I concur with the plausibility of this pathway, owing to recent findings of viral RNA detection in stool samples and enteric symptoms experienced by several cohorts of COVID-19patients., In the absence of any reports of faecal-oral transmission, this remains a hypothesis, albeit highly probable.Although the suggested infection control measures for oral healthcare settings seem practical, a thorough awareness of transmission routes is pre-requisite to devising effective advice.
