AbstractAs reported by the World Health Organization, a novel coronavirus (2019-nCoV) was identified as the causative virus of Wuhan pneumonia of unknown etiology by Chinese authorities on 7 January, 2020. In this study, we developed a Bats-Hosts-Reservoir-People transmission network model for simulating the potential transmission from the infection source (probable be bats) to the human infection. Since the Bats-Hosts-Reservoir network was hard to explore clearly and public concerns were focusing on the transmission from a seafood market (reservoir) to people, we simplified the model as Reservoir-People transmission network model. The basic reproduction number (R0) was calculated from the RP model to assess the transmissibility of the 2019-nCoV.

The chronology of COVID-19 infections shows us that the first cases were reported in December 2019. A number of patients were admitted to hospitals with a respiratory disease of an unknown etiology in Wuhan, Hubei Province, China. The patients presented symptoms such as coughing, persistent fever, sore throat and pneumonia. The respiratory infection situation got worse rapidly and had a very fast spread. Soon after, it was reported that the causing agent of the disease had been confirmed as the novel Coronavirus (SARS-CoV-2), which belongs to the subfamily Orthocoronavirinae, of the family Coronaviridae in the order Nidovirales. On January 7, 2020, the disease was named as Coronavirus Disease 2019 (COVID-19) by the World Health Organization (WHO). Chloroquine (CQ), Hydroxychloroquine (HCQ), Remdesivir, Heparin, Convalescent Plasma, Corticosteroid, Anticoagulants, Lopinavir, Ritonavir, Ivermectin and Nitazoxanide are some of the drugs on the market that are being tested to combat COVID-19. The purpose of this literature review is to analyze studies regarding the healing potential of these drugs for COVID-19.  Some researchers about the effectiveness of these medications, the success rate on viral diseases and its action potential by different mechanisms. Thus, given the researches analyzed in this study, it was evident for most authors that these drugs are promising treatments for COVID-19, while the vaccine is not manufactured and available.

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.

The World Health Organization (WHO) has recently announced the spread of novel coronavirus (nCoV) globally and has declared it a pandemic. The probable source of transmission of the virus, which is from animal to human and human to human contact, has been established. As per the statistics reported by the WHO on 11th April 2020, data has shown that more than sixteen lakh confirmed cases have been identified globally. The reported cases related to nCoV in India have been rising substantially. The review article discusses the characteristics of nCoV in detail with the probability of potentially effective old drugs that may inhibit the virus. The research may further emphasize and draw the attention of the world towards the development of an effective vaccine as well as alternative therapies. Moreover, the article will help to bridge the gap between the new researchers since it’s the current thrust area of research.

UNSTRUCTURED Coronaviruses belong to a large family of viruses. Coronavirus also called COVID-19 is a new disease that has not been previously identified in humans. The World Health Organization has announced that COVID-19 is a pandemic. Currently there is no specific vaccine or treatment for COVID-19. Current treatment for COVID-19 is only supportive (treating the symptoms). There are no antiviral or vaccine options at this time. Therefore, it is time to bring collective efforts to treat or prevent a rapidly evolving pandemic of 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.
