This study aimed to investigate the most common Coronavirus pathogens in humans in the third millennium. In this study, all documents in English on pathogenic coronaviruses were examined from the beginning of 2002 to March 27, 2020. Articles were searched through reliable databases such as PubMed, Web of Science, Scopus, Google scholar, Science Direct, Cochrane library, and BioRxiv using the keywords "COVID-19", "Coronavirus 2019", "SARS-CoV," and" MERS-CoV." In addition, reliable health websites, such as WHO and the Centers for Disease Control and Prevention (CDC), were used to obtain new figures and information on these diseases. A total of 1563 articles and documents were extracted, and after reviewing the full texts of these articles, 100 papers and documents with necessary eligibility were finally selected in the present review study. The outbreak of pathogenic viruses, especially the latest one, i.e., COVID-19, as a severe threat can affect the entire global community, in particular medical staff who are at the forefront of fighting against the virus. It can generally be concluded that coronaviruses have high pathogenesis, with very rapid person-to-person transmission. Since human knowledge is not yet complete about the new type of this virus, i.e., COVID-19, there are no definitive treatments for the virus. Thus, the best and only way to prevent affection from this virus is currently fully implementing health protocols and preventing self-infection and the virus outbreak.

Background and Objectives: Academic procrastination can have an adverse effect on students' educational, communicational, health, and career prospects. Therefore, recognizing the factors affecting academic procrastination among students is essential. The aim of this study was to determine the correlation between academic procrastination with emotional intelligence and self-efficacy among operating room students of Shiraz University of Medical Sciences. Methods: This descriptive cross-sectional correlational study was performed on 95 operating room students of Shiraz University of Medical Sciences. Data collection tools included demographic information questionnaires, academic procrastination questionnaire, Scherer general self-efficacy scale and schutte self-report emotional intelligence scale. Data were analyzed using one-way analysis of variance, Pearson correlation coefficient and simultaneous multiple regression by SPSS software version 21. Results: The Mean±‌SD scores of academic procrastination, self-efficacy and emotional intelligence were 20.6±‌8.7, 63.1±‌9.3 and 119.2±‌17.6, respectively. There was a significant and inverse correlation between academic procrastination with self-efficacy (P‌=‌ 0.001, r‌=‌ -0.339) and emotional intelligence (P‌=‌0.007, r‌=‌ -0.276). The results of regression analysis showed that the model of predicting academic procrastination based on self-efficacy is significant (P‌=‌0.035). Academic procrastination based on emotional intelligence was not significant (P‌=‌0.474). Conclusion: The results of this study show that academic procrastination is less among students with higher self-efficacy and emotional intelligence.
