“…Another reason for possible data skew may be the origin of the current pandemic being China. Indeed, a recent study analysed the publications in COVID-19 literature hub LitCovid [56] and observed that more than 30% of articles were related to China [57]. These aspects of possible bias and data skew are addressed in the Discussion to make sure that the valid conclusions are drawn from the data in terms of geographical correlation.…”

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; initially named as 2019-nCoV) is responsible for the recent COVID-19 pandemic and polymerase chain reaction (PCR) is the current standard method for its diagnosis from patient samples. This study conducted a reassessment of published diagnostic PCR assays, including those recommended by the World Health Organization (WHO), through the evaluation of mismatches with publicly available viral sequences. An exhaustive evaluation of the sequence variability within the primer/probe target regions of the viral genome was performed using more than 17 000 viral sequences from around the world. The analysis showed the presence of mutations/mismatches in primer/probe binding regions of 7 assays out of 27 assays studied. A comprehensive bioinformatics approach for in silico inclusivity evaluation of PCR diagnostic assays of SARS-CoV-2 was validated using freely available software programs that can be applied to any diagnostic assay of choice. These findings provide potentially important information for clinicians, laboratory professionals and policy-makers.

“…The hub is updated daily with newly published articles and includes the most comprehensive database of international research articles related to COVID-19 in PubMed. LitCovid Hub has a more sophisticated search function than the available collection and identifies more 35% relevant articles through keyword-based searches for terms such as COVID-19, nCOV, 2019-nCoV, and other related search terms 11 . The total number of articles in LitCovid Hub is more than that of Scopus and Web of Science in the same period 11 .…”

Introduction: The outbreak of the novel coronavirus disease 2019 (COVID-19) is an ongoing global epidemic incident. The present study aims to bibliometrically analyze the global research trends of scientific papers related to COVID-19 with regard to the number of publications, subject categories, and prolific countries. A total of 47,061 publications, published during the last seven months, were collected and analyzed in this study. Methods: The bibliometric data in this study, which was extracted from the LitCovid Hub from January 17 to July 31, 2020. Results: Our results indicate that the number of publications on COVID-19 has increased significantly from January to July 2020, along with the rapid spread of the infection. China has produced the largest number of research papers on COVID-19 (5,751 articles, accounting for 12.2%), followed by the USA (2,005 publications, accounting for 4.3%) and Italy (1,374 publications, accounting for 2.9%). Most recent research papers have focused on prevention, treatment, and diagnosis. Our results reveal that although the most affected countries are the USA, Brazil, India, and many countries in Europe, their contribution to research about COVID-19 has been limited. Conclusion: More research in the field of prevention, diagnosis, and treatment from highly affected countries is recommended. Overall, this study not only provides a global status update on COVID-19 scientific literature but also contributes to future research.

Background: Considering the importance of the hand hygiene behaviors for the prevention of COVID-19 transmission, the current study was conducted to investigate the changes in hand-washing behaviors and its related factors among the northern Iranian population during the first peak and subsidence of COVID-19 pandemic period.Methods: This cross-sectional study was conducted during two periods in Guilan (Northern provinces of Iran). First period conducted at the first peak of COVID-19 pandemic in Iran (between 03/23/2020 and 03/30/2020), and second period conducted at the first subsidence of COVID-19 pandemic in Iran (between 05/3/20 and 05/10/2020). The questionnaire was completed by 571 adult participants. Data on frequency, procedure and circumstances of hand-washing and obsessive-like behaviors were collected. Potential correlates of reduction in frequency of hand washing were analyzed by multiple logistic regression.Result: Compared to peak of COVID-19 pandemic, frequency and procedure of hand-washing and obsessive-like behaviors were significantly reduced at the subsidence of COVID-19 pandemic (all p<0.05). Females with negative family history of coronavirus disease had greater odds (Adjusted Odds Ratio = 2.19, P =0.03) of reduction in the frequency of daily hand-washing. Younger than 50 years old males and males who reduced the procedure of hand-washing had greater odds (AOR = 1.71, P =0.02 and AOR = 2.16, P =0.001, respectively) of reduction in the frequency of daily hand-washing. Conclusion: Northern Iranian populations were found to decrease their frequency and quality of hand washing and obsessive-like behaviors over time from the first peak to first subsidence of COVID-19 pandemic. Here, the factors that independently predicted reduction in frequency of hand washing in male population were younger age and reduction in procedure of hand-washing and in female population was a negative family history of coronavirus disease. Thus, special attention should be paid to maintaining the general population’s perceived susceptibility to illness, especially in younger men during the pandemic.
