ABSTRACT
Corona Virus Disease 2019 (COVID-19) has broke out in 29 countries and regions in the world in a short period since December 2019. Various measures of prevention and control have been taken all over China. At present, the epidemic situation shows a positive trend, however, there are still a few new comfirmed cases in some area of China. So the job and thinking of epidemic prevention still cannot be relaxed. As an important specialty of stomatology, the risk of cross infection is high in oral medicine. Establishing an effective system of pre- inspection and triage and adopting strict measures of prevention and control are essential. According to the prevention and control situation of COVID- 19, the characteristics of hospital infection, pre examination, protective measures, the home management strategies of oral mucosal diseases during the epidemic period and the differential diagnosis between COVID-19 and common oral muco- sal diseases with fever were summarized and recommended in this paper.
ABSTRACT
The infected and fatal cases of Coronavirus Disease 2019 (COVID-19) keep increasing around the world, to explore the infection routes and pathogenesis of 2019-nCoV could be meaningful for prevention and treatment of COVID-19. Previous studies showed that the oral cavity is at potentially high risk of 2019-nCoV infection. The ACE2 receptor of 2019-nCoV was reported could express on oral epithelium and salivary glands, and 2019-nCoV could be detected in patients’ saliva. Recently, the amblygeustia were found to widely exist in the COVID-19 patients. To explore the potential mechanism of amblygeustia, we performed further analysis via independent in-house single-cell profiles. Our results showed that ACE2 was inclined to express in taste cells, which indicated that 2019-nCoV may invade into taste cells at the early stage of COVID-19, and lead to the amblygeustia of patients. Above findings about the 2019-nCoV and COVID-19 in oral cavity are valuable and enlightening for future epidemic prevention strategy.
