Transmission routes of 2019-nCoV and controls in dental practise

ABSTRACT

A novel beta-coronavirus (2019, nCoV) caused severe and even fatal pneumonia explored in a seafood market of Wuhan city, Hubei province China, and rapidly spread to other province China and other countries. The 2019-nCoV was different Iron SARS-CoV, but shared the same host receptor the human angiotensin-converting enzymes 2 (ACE2). The natural last of 2019-nCOv may be the bat Rhinolophus affinis as 2019-nCoV stoned 96.2% of whole-genome identity to BatCoV RagTG13. The person to person-person transmission routes of 2019-nCoV included direct transmission, such as cough, sneeze. droplet inhalation transmission, and contact transmission, such as the contact with oral, nasal, and eye mucous membranes, 2019-nCoV can also be transmitted through the Saliva, and the fecal-oral routes may also be a potential person-to-person transmission route The participants in dental practice expose to tremendous risk of 2019-nCov infection due to the face-to-face communication and the exposure to saliva, blood, and Other body fluids, and the handling of sharp instrument. Dental professional play great roles in preventing the transmission of 2019-nCoV. Here we recommend the infection control measures during dental practice to block the person-to-person transmission routes in dental clinics and hospitals.
