We first conducted time-series analysis of mono- and dinucleotide composition for over 10,000 SARS-CoV-2 genomes, as well as over 1500 Zaire ebolavirus genomes, and found clear time-series changes in the compositions on a monthly basis, which should reflect viral adaptations for efficient growth in human cells. We next developed a sequence alignment free method that extensively searches for advantageous mutations and rank them in an increase level for their intrapopulation frequency. Time-series analysis of occurrences of oligonucleotides of diverse lengths for SARS-CoV-2 genomes revealed seven distinctive mutations that rapidly expanded their intrapopulation frequency and are thought to be candidates of advantageous mutations for the efficient growth in human cells.The outbreak of pneumonia caused by a new coronavirus (SARS-CoV-2) occurred in December 2019, and spread rapidly throughout the world. There have been other severe coronavirus outbreaks worldwide, namely, severe acute respiratory syndrome (SARS-CoV) and Middle East respiratory syndrome (MERS-CoV). Because the genetic diversity of coronaviruses renders the design of vaccines complicated, broad spectrum-anti-coronavirus drugs have become a critical approach to control the coronavirus epidemic. Cyclophilin A is an important protein needed for coronavirus replication, and its inhibitor cyclosporine A has the ability to suppress coronavirus on a broad spectrum. Chk inhibitor CD147-S protein was found to be one route by which SARS-CoV-2 invades host cells, while CD147 was found to play a functional role in facilitating the infection of host cells by SARS-CoV. The CyPA/CD147 interaction may play a critical role in the ability of the SARS-CoV-2 virus to enter the host cells. However, cyclosporine A has immunosuppressive effects, so the conditions for its use as an antiviral drug are limited. As a result, cyclosporine A analogues without immunosuppressive side effects have attracted lots of interest. This review primarily discusses the drug development prospects of cyclophilin A as a therapeutic target for the treatment of coronavirus infection, especially coronavirus disease 2019 (COVID-19), and non-immunosuppressive cyclosporine analogues.Coronavirus disease (COVID-19) is a major pandemic and now a leading cause of death worldwide. Currently, no drugs/vaccine is available for the treatment of this disease. Future preventions and social distancing are the only ways to prevent this disease from community transmission. Vitamin D is an important micronutrient and has been reported to improve immunity and protect against respiratory illness. This short review highlights the important scientific link between Vitamin D levels and susceptibility to COVID-19 in patients. This review also discusses recommendations for Vitamin D dose required for healthy as well as COVID-19 susceptible patients for protection and prevention.The Bacillus Calmette-Guerin vaccine (BCG vaccine) designed to prevent tuberculosis in children has been shown to induce a adaptive immune response in the body to fight against bacteria as well as other parasites and viruses. This knowledge has been reciprocated to generate the idea that this vaccine can also offer protection against severe acute respiratory syndrome coronavirus-2 (SARS-COV-2). Some recent pre-print articles have highlighted that countries with mass BCG immunizations seems to have a lower incidence of coronavirus disease 2019 (COVID-19) compared to those without BCG immunization. There are yet no experimental proof of any such association and the world health organisation (WHO) is currently testing the theory with clinical trials on selected cohorts. Epidemiologists and other scientific experts has expressed both their hope and concern simultaneously regarding the success theory of BCG vaccination to prevent COVID-19. Though its still not verified in any way whether the BCG vaccination can actually prevent COVID-19 or not but we believe a thorough analytical research in this regard is indeed worth a shot.This study aimed to determine the clinical characteristics of patients diagnosed with the coronavirus disease 2019 (COVID-19). Clinical data of COVID-19 patients diagnosed between January 28, 2020 and February 23, 2020 at the Beijing You'an Hospital were summarized and analyzed. Overall, 45 (18 men and 27 women) patients were included in this study. The average age of patients was 58 years (range, 7-94 years). Furthermore, 21 patients (47%) experienced underlying chronic diseases, with another four patients (9%) having three or more chronic diseases simultaneously. The first symptoms appeared at the onset of illness onset include fever in 36 patients (80%), cough in 23 patients (51%), and expectoration in 15 patients (33%), respectively. Patients may experience hepatic and renal injury as well as abnormal myocardial enzymes in varying degrees. Senior patients (≥58) and accompanying chronic diseases were considered as independent predictors for developing a severe and critically ill population with increased mortality. Laboratory results regarding the NEU percentage, NLR, ALC, and C-reactive protein levels were considered significant in predicting clinically critical disease or for prognosis assessment and thus require further studies. COVID-19 may affect multiple organs of the human body. Glucocorticoid is considered effective in the treatment of patients diagnosed with severe COVID-19.As of March 12th Italy has the largest number of SARS-CoV-2 cases in Europe as well as outside China. The infections, first limited in Northern Italy, have eventually spread to all other regions. When controlling an emerging outbreak of an infectious disease it is essential to know the key epidemiological parameters, such as the basic reproduction number R0, i.e. the average number of secondary infections caused by one infected individual during his/her entire infectious period at the start of an outbreak. Previous work has been limited to the assessment of R0 analyzing data from the Wuhan region or Mainland China. In the present study the R0 value for SARS-CoV-2 was assessed analyzing data derived from the early phase of the outbreak in Italy. In particular, the spread of SARS-CoV-2 was analyzed in 9 cities (those with the largest number of infections) fitting the well-established SIR-model to available data in the interval between February 25-March 12, 2020. The findings of this study suggest that R0 values associated with the Italian outbreak may range from 2.
