Because of the frequent emergence of novel microbial species and the re-emergence of genetic variants of hitherto known microbes, the global healthcare system, and human health has been thrown into jeopardy. Also, certain microbes that possess the ability to develop multi-drug resistance (MDR) have limited the treatment options in cases of serious infections, and increased hospital and treatment costs, and associated morbidity and mortality. The recent discovery of the novel Coronavirus (n-CoV), the Severe Acute Respiratory Syndrome CoV-2 (SARS-CoV-2) that is causing the CoV Disease-19 (COVID-19) has resulted in severe morbidity and mortality throughout the world affecting normal human lives. The major concern with the current pandemic is the non-availability of specific drugs and an incomplete understanding of the pathobiology of the virus. It is therefore important for pharmaceutical establishments to envisage the discovery of therapeutic interventions and potential vaccines against the novel and MDR microbes. Therefore, this review is attempted to update and explore the current perspectives in microbes, clinical research, drug discovery, and vaccine development to effectively combat the emerging novel and re-emerging genetic variants of microbes.

Background: Humans can be infected with various coronaviruses that cause serious illness and death. One such pandemic strain of coronavirus was recently identified in December 2019 and lead to a devastating outbreak in Wuhan city of China. It is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is highly contagious which causes symptoms such as fever, cough and shortness of breath. Objective: The objective of this review is to highlight the current understanding, research and therapeutic updates of the novel coronavirus disease 2019 (COVID-19). Methods: A thorough literature search was conducted for research papers and patents in context to COVID-19. All articles with respect to this subject was taken from various public repositories such as Google Scholar, Pubmed, ScienceDirect (Elsevier), Springer, Web of Science, etc. Results: The present analysis showed that key areas of the inventions were the vaccines and diagnostic kits apart from the composition for the treatment of CoV. It was also observed that no specific vaccine treatments are available for the treatment of 2019-nCov; however, developing novel chemical or biological drugs and kits for early diagnosis, prevention, and disease management is the primary governing topic among the patented inventions. The present study also indicates potential research opportunities for the future, particularly to combat 2019-nCoV. The current focus of the researches has turned towards developing four potential treatments including development of candidate vaccine, development of novel potential drugs, repurposing of existing drugs and development of convalescent plasma therapy. The PCR based diagnosis is the gold standard for the COVID-19 testing but it require resource time, expertise and high associated cost hence the researchers are also developing different diagnosis methods for the COVID-19. Although vaccines are being developed by various companies and have passed the pre-clinical stages but still there exists no guarantee for these to become the effective vaccine. The current treatments which are being used for COVID-19 patients are not well established and have limited success. Conclusion: The pandemic has challenged the medical, economic and public health infrastructure across globe. There is urgent need to explore all available and possible methods/approaches to study this disease for drug and vaccine development at the earliest.

A novel coronavirus (SARS-CoV-2), causing an emerging coronavirus disease (COVID-19), first detected in Wuhan City, Hubei Province, China has resulted in an outbreak in China which has taken a catastrophic turn with high toll rates in China and subsequently spreading across the globe. The rapid spread of this virus to more than 175 countries while affecting nearly 500,000 persons and causing more than 22,000 human deaths, it has resulted in a pandemic situation in the world. The SARS-CoV-2 virus belongs to the genus Betacoronavirus, like MERS-CoV and SARS-CoV, all of which originated in bats. It is highly contagious, causing symptoms like fever, dyspnea, asthenia and pneumonia, thrombocytopenia and the severely infected patients succumb to the disease. Coronaviruses (CoVs) among all known RNA viruses have the largest genomes ranging from 26 to 32 kb in length. Extensive research has been conducted to understand the molecular basis of the SARS-CoV-2 infection and evolution, develop effective therapeutics, antiviral drugs and vaccines, and to design rapid and confirmatory viral diagnostics as well as adopt appropriate prevention and control strategies. Till date, no clinically proclaimed, proven therapeutic antibodies or specific drugs and therapeutics, and vaccines have turned up. Several molecular diagnostic tests such as Real Time-PCR, isothermal loop-mediated amplification of coronavirus (i-LACO), full genome analysis by next-generation sequencing (NGS), multiplex nucleic acid amplification, and microarray-based assays are in use currently for the laboratory confirmation of this CoV infection. In this review article, we describe the basic molecular organization and phylogenetic analysis of the coronaviruses, including the SARS-CoV-2, and recent advances in diagnosis and vaccine development in brief and focusing mainly on developing potential therapeutic options that can be explored to manage this pandemic virus infection, which would help in valid countering of COVID-19.

Sudden prevalence of coronavirus disease-2019 (COVID-19) has badly impeded and collapsed the emerging global trend of economic development by its ongoing pandemic. The novel coronavirus also named severe acute respiratory syndrome virus – 2 (SARS-CoV-2) causes the disease COVID-19 that influences the health management of humans and the world commerce badly. It has affected the human social lives and education in underdeveloped countries and severely impeded industries, organizations, agriculture, etc. Three perceptible types of SARS-CoV-2 strains have been discovered. Each of them has specific receptors, and some of them are common in SARS and SARS-CoV-2. Among them, the ACE2 receptor is believed to be the central receptor of human infectious coronaviruses. It supports mainly to get access, enter into the cell, and causes the basic infection. Similarly, TMPRSS2 is also acting as a portal for a virus to get an approach to the cell and does not support metabolic processes like replication virus. ADAM17, which is a member of disintegrins and metalloproteases and is responsible for cell to cell and cell-array interconnections. These receptors can be important for prevention, vaccine development, and therapies. Several therapies in SARS-CoV-2 infected patients have been tried and suggested. Plasma and stem cell therapy reduce the severity of infection at certain levels in individual patients. In this review, we make an effort to cover all of the said aspects of COVID-19 in a very compressive and brief way. Finally, we shed light on vaccination and therapeutic approaches like plasma therapy and stem therapy and their future perspective with the whole discussion conclusion.
