Background: COVID-19 is a new, health-threatening infectious disease in the world in 2020, caused novel coronavirus SARS-CoV-2. As of July 13, 2020, 4,881,579 active cases of COVID-19 have been diagnosed and 571,080 deaths globally. In India, 301,850 active cases and 23,187 deaths have been reported. To date, there is no effective treatment made available against the deadly virus SARS-CoV-2. The drug manufacturers, institutional laboratories, and other organizations start developing vaccines to combat the COVID-19 infection. Methods: Science Direct, Elsevier, Pub med, Scopus, and Nature databases were referred to know the current scenario of disease. Moreover, the recent data has also been obtained from the World Health Organization (WHO), Centre of Disease Control (CDCs), case studies, newspaper, and worldometer reports. Vaccine Centre at the London School of Hygiene & Tropical Medicine, Clinicaltrials.gov, US National Library of Medicine, has also been accessed to get the latest information about ongoing clinical trials. Result: The primary source of the SARS-CoV-2 outbreak is connected to the Hunan seafood and live animal market in Wuhan city, Hubei Province, China. Like; SARS-CoV, and MERS-CoV, SARS-CoV-2 is also a zoonotic virus affecting the lower respiratory tract in humans. The pathogenesis of COVID-19 involves attachment of its Spike (S) protein to the angiotensin-converting enzyme 2 (ACE2) receptor in the lower respiratory tract in humans. The most common symptoms of COVID-19 are fever, cough, sore throat, fatigue, headache, myalgia, septic shock, and breathlessness. Few patients with COVID-19 infection experience diarrhea, vomiting, and abdominal pain. Currently, FDA approved drugs being used to treat COVID-19. Conclusion: This review article presents the importance of traditional Indian herbs recommended by AYUSH as precautionary and curative measures of COVID-19 until vaccines and drugs are made available. Moreover, this article discussed the origin, symptoms, mode of transmission, management, and diagnostics techniques for the detection of the SARS-CoV-2 virus.

In December of 2019, an outbreak of a novel coronavirus flared in Wuhan, the capital city of the Hubei Province, China. The pathogen has been identified as a novel enveloped RNA beta-coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus SARS-CoV-2 is associated with a disease characterized by severe atypical pneumonia known as coronavirus 2019 (COVID-19). Typical symptoms of this disease include cough, fever, malaise, shortness of breath, gastrointestinal symptoms, anosmia, and, in severe cases, pneumonia.1 The high-risk group of COVID-19 patients includes people over the age of 60 years as well as people with existing cardiovascular disease and/or diabetes mellitus. Epidemiological investigations have suggested that the outbreak was associated with a live animal market in Wuhan. Within the first few months of the outbreak, cases were growing exponentially all over the world. The unabated spread of this deadly and highly infectious virus is a health emergency for all nations in the world and has led to the World Health Organization (WHO) declaring a pandemic on March 11, 2020. In this report, we consolidate and review the available clinically and preclinically relevant results emanating from in vitro animal models and clinical studies of drugs approved for emergency use as a treatment for COVID-19, including remdesivir, hydroxychloroquine, and lopinavir-ritonavir combinations. These compounds have been frequently touted as top candidates to treat COVID-19, but recent clinical reports suggest mixed outcomes on their efficacies within the current clinical protocol frameworks.

Novel Coronavirus are very harmful virus. This viruses have positive single stranded RNA genome and enveloped which is called nucleocapsid. The family of this virus is Coronaviridae. This virus originated from species of avian and mammalian. This virus effect on upper respiratory tract in humans. Many species of these novel coronaviruses (HCoVs) are named as HCoV-HKU1, HCoV-NL63. Predominant species of this virus is Middle East respiratory syndrome (MERS-CoV) across the world.  In both adults and childrens HCoV-HKU1 sp. is causes for chronic pulmonary disease and HCoV-NL63 species causes for upper and lower respiratory tract disease. Most recent species of this virus is MERS-CoV. This species caused for acute pneumonia and occasional renal failure. The new strain of novel Coronavirus is SARS-CoV-2. This strain causes for the Coronavirus Disease 2019 (COVID-19). This disease named by the World Health Organization. Now world fighting against COVID-19 and according to the recent statistics report of world about the COVID-19 cases approx 22.6M confirmed cases and 792K death cases appeared and recovered 14.5M. COVID-19 disease starts to spread from December 2019 from china. Covid-19 disease is emerged in Wuhan seafood market at Wuhan of South China and then rapidly spread throughout the world. The corona virus outbreak has been declared a public health emergency of International concern by World Health Organization (WHO). In this article we summarize the current clinical characteristics of coronavirus and diagnosis, treatments and prevention of COVID-19 disease. In this review article, we analyze data from various Research Reports like WHO guidelines and other articles. It is very important to the readers that new data of COVID-19 updating nearly every hour of day regarding clinical characteristics, diagnosis, treatment strategies, and outcomes COVID-19 disease. The degree of COVID-19 disease varying throughout the world. COVID-19 affected patient shows various symptoms like fever, cough, sore throat, breathlessness, fatigue, and malaise among others. The COVID-19 disease is being treated through general treatment like symptomatic treatment, by using antiviral drugs, oxygen therapy and by the immune system. There is no vaccine or therapeutic strategies for deal with this disease yet. In this critical situation preventive measures must be require.  A very important issue in preventing viral infection is hand hygiene. There are other entities that people can boosting the immune system and help in infection prevention.

Coronaviruses are a family of viruses that cause illness such as respiratory diseases or gastrointestinal diseases. Respiratory diseases can range from the common cold to more severe diseases. A novel coronavirus outbreak was first documented in Wuhan, Hubei Province, China in December 2019. The World Health Organization (WHO) has declared the coronavirus disease 2019 (COVID-19) a pandemic. A global coordinated effort is needed to stop the further spread of the virus. A novel coronavirus (nCoV) is a new strain that has not been identified in humans previously. Once scientists determine exactly what coronavirus it is, they give it a name (as in the case of COVID-19, the virus causing it is SARS-CoV-2).

Epidemiological Characteristics

Currently, the world is facing a health and socioeconomic crisis caused by the novel coronavirus disease COVID-19. On 11 March 2020, the World Health Organization (WHO) has declared this disease as a pandemic. The condition (COVID-19) is an infectious disorder triggered by a newly discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2. Most of the COVID-19 infected patients will experience mild to moderate respiratory symptoms and recover without any unique therapy. Assessment of the clinical and epidemiological characteristics of SARS-CoV-2 cases suggests the infected patients will not be contagious until the onset of severe symptoms and affects the other organs. Well-differentiated cells of apical airway epithelia communicating with ACE2 were promptly infected to SARS-CoV-2 virus. But the expression of ACE 2 in poorly differentiated epithelia facilitated SARS spike (S) protein-pseudo typed virus entry and it is replicated in polarized epithelia and especially exited via the apical surface. Limiting the transmission of COVID-19 infection & its prevention can be regarded as a hierarchy of controls. In this article, we briefly discuss the most recent advances in respect to aetiology, pathogenesis and clinical progression of the disease COVID-19.

Influenza is a highly known contagious viral infection that has been responsible for the death of many people in history with pandemics. These pandemics have been occurring every 10 to 30 years in the last century. The most recent global pandemic prior to COVID-19 was the 2009 influenza A (H1N1) pandemic. A decade ago, the H1N1 virus caused 12,500 deaths in just 19 months globally. Now, again, the world has been challenged with another pandemic. Since December 2019, the first case of a novel coronavirus (COVID-19) infection was detected in Wuhan. This infection has risen rapidly throughout the world; even the World Health Organization (WHO) announced COVID-19 as a worldwide emergency to ensure human health and public safety. This review article aims to discuss important issues relating to COVID-19, including clinical, epidemiological, and pathological features of COVID-19 and recent progress in diagnosis and treatment approaches for the COVID-19 infection. We also highlight key similarities and differences between COVID-19 and influenza A to ensure the theoretical and practical details of COVID-19.
