Knowledge, attitude and practice of dental practitioners, interns and post-graduate trainees about COVID-19 pandemic in Chennai.

BACKGROUND: Coronavirus disease-2019 COVID-19) pandemic has been sweeping around the globe and the cases have been reported in India since the second week of March, with Chennai being one of the most affected cities. Healthcare professionals, particularly the dental personnel have a higher risk of infection due to close face-to-face contact and the risk of inhalation of aerosolised particles. AIM: The aim of this study was to assess the knowledge, attitude and practice about COVID-19 among interns, post-graduate trainees and dental practitioners. MATERIAL AND METHODS: A cross-sectional survey was conducted using Google forms among three groups: interns, post-graduate trainees and dental practitioners. Data obtained was analysed by Chi-square test, Kruskal-Wallis and post hoc test using SPSS IBM software. RESULTS: Of total score of 9 for knowledge-based questions, the score obtained by interns, post-graduate trainees and practitioners were 7.2, 7.2 and 7.5, respectively, with no statistically significant difference among the groups (P = 0.24). Of total score of 4 for attitude-based questions, the score obtained by interns, post-graduate trainees and practitioners were 1.6, 2.0, and 1.9, respectively, with statistically significant difference among the groups (0.009). Of total score of 7 for practice-based questions, the score obtained by interns, post-graduate trainees and practitioners were 3.2, 3.3, and 3.1, respectively, with no statistically significant difference among them (P = 0.63). CONCLUSION: Though the knowledge about COVID-19 appeared adequate, the attitude and practice component needs improvement. Continuing dental education programs and webinars can be conducted to update the dental professionals about the protocols to be followed during COVID-19 pandemic.

Coronavirus disease 2019 and its vaccines: An update.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by coronavirus. Most of the people infected with the COVID-19 virus will experience mild-to-moderate respiratory illness and recover without requiring special treatment. Older people and those with underlying medical problems are more likely to develop serious illness. In December 2019, a novel coronavirus designated as severe acute respiratory syndrome (SARS) coronavirus 2 emerged in the city of Wuhan, China, and caused an outbreak of unusual viral pneumonia. Being highly transmissible, this novel coronavirus disease, also known as COVID-19, has spread fast all over the world. It has overwhelmingly surpassed SARS and Middle East respiratory syndrome in terms of both the number of infected people and the epidemic areas. Currently, there is no definite treatment for COVID-19 although some drugs are under investigation. Infections caused by these viruses are an enormous global health threat. Hence, the government has established fast-tracking research to develop rapid diagnostic test kits and vaccines at low cost. This review highlights the vaccines available against COVID 19 worldwide and its implications.
