ABSTRACT
On January 30, 2020, the World Health Organization (WHO) declared a severe respiratory disorder syndrome which originated in Wuhan city as a global public health emergency, and the pandemic declaration by the WHO was made on March 11, 2020. Persons infected with SARS-CoV-2 are frequently asymptomatic, yet they have high respiratory viral loads, and they are major purveyors of viral spread. These factors have led to the current explosion of COVID-19 hospitalizations and deaths. Vaccines could play an important role by preventing severe diseases and increasing population immunity and reducing the ongoing health crisis. There is wealth of information for the review available since it is a current topic of interest. Initially, Google Scholar was utilized to take an initial sample of what types of articles are available. We searched other databases such as PubMed, EMBASE, and COCHRANE LIBRARY for research articles published up to March 2021, with no language restrictions. We found seven peer-reviewed publications available on the efficacy of SARS-CoV-2 vaccines: AZD1222 (AstraZeneca/University of Oxford), a ChAdOx1-based vaccine with a reported efficacy of 70.4% and two mRNA-based vaccines: BNT162b2 (Pfizer/BioNTech) with a reported efficacy of 95% and mRNA-1273 (Moderna/NIAID) with a reported efficacy of 94.1%. Internet was used as a source because of its limitless networking of resources. Sources used from the internet were written by professionals in their fields and published on reliable sites, in referred publications, or on professional organization sites. The cited references were within the last 2 years.
ABSTRACT
Introduction: Coronavirus belongs to family of Coronaviridae, which primarily infect the upper respiratory and gastro intestinal tract of birds & mammals. It is an enveloped virus with positive-sense single-stranded RNA. Patients with COVID-19 are usually present with symptoms of fever, dry cough, myalgia, dysgeusia, nausea, diarrhoea, hyposmia and later it progresses into pneumonia. Dentists are at potential risk because they are in consistent exposure of blood and saliva, so they should have knowledge of COVID-19 infection, transmission & prevention for proper infection control practices. Aims and Objectives: The aim of the study is to assess the knowledge and perception of DHPs toward COVID-19. Methodology: A cross-sectional study was undertaken among practicing dental professionals in Lucknow city (U.P) India. A total of 302 Dental Health Practitioners (DHPs) participated in the study. Knowledge was assessed using self-administered, structured questionnaire. The questions were administered online through Google Forms by sending link to the registered Dentist through E-mail. Results: A total of 350 DHPs were participated in the study, among which 302 DHPs has given complete responses and was included in the analysis. Simple linear regression showed a significant relationship between knowledge with age of dentist (p < 0.001), qualification as MDS (p = 0.025), practice as private (p < 0.001), experience between 5 and 10 years (p = 0.009), and experienced more than 10 years(p = 0.006). Correct answers in each sections of questionnaire were defined an internal consistency was assessed using Cronbach`s alpha. Conclusion: Despite having high standard of knowledge, practices and perceptions DHPs around the world are in a state of anxiety and fear while working in their respective field due to COVID-19 impact. DHPs are advised to follow the guidelines for clinical recommendations given by health authorities like WHO, CDC, ADA and IDA.
