Corona Virus Disease (Covid – 19): A World Threatening Pandemic
2020
With the emergence of Corona virus Disease (COVID – 19) caused by the spread of 2019 novel Corona virus (2019-nCoV) the world is facing a new public health crisis. This virus is also known as Severe Acute Respiratory Syndrome Corona virus 2 (SARS-CoV-2). It is rapidly spreading from its origin in Wuhan City of Hubei Province of China in December 2019 to the rest of the world. It has affected over 200 countries in the world including India. Therefore, it is declared as a global public health emergency by the World Health Organization (WHO). This virus was transmitted to humans from animals and initially causes mild symptoms like fever, cough and fatigue in most people. But in some cases the symptoms become severe leading to pneumonia, acute respiratory distress syndrome (ARDS) and multi organ dysfunction. The diagnosis of this disease relies on a special molecular test. Since the research on novel Corona virus is on the preliminary stage no specific drug or vaccine has been developed...

https://www.ijrrjournal.com/IJRR\_Vol.7\_Issue.9\_Sep2020/Abstract\_IJRR0023.html, 2020
Novel strain of coronavirus has evolved at the end of 2019 and was labelled as Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), causing severe acute respiratory syndrome expanded globally from Wuhan, China. By the end of March 2020, the World Health Organization declared the COVID-19 virus a global pandemic. A brief review describing the existing literature available regarding Corona Virus epidemiology, clinical manifestations, management and future preparedness required is dealt in this article. Though only when the pandemic ends it will be possible to assess the full health, social and economic impact of this global disaster.
Coronavirus disease‑2019 (Review)
World Academy of Sciences Journal, 2021
From the end of 2019, an ongoing outbreak of a new type of unexplained pneumonia caused by a novel coronavirus, Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China. Since then, it has spread to most parts of China and worldwide, thus affecting the health of individuals worldwide. Until August 2020, >25 million cases of SARS-CoV-2 infection had been confirmed worldwide, causing >800,000 deaths. This disease was named by the World Health Organization as coronavirus disease 2019 (COVID-19). Similar to SARS and Middle East Respiratory Syndrome, which are also caused by coronavirus infections, COVID-19 mainly causes severe respiratory system damage; however, it also causes damage to multiple organs, including the gastrointestinal tract, the cardiovascular system and the nervous system. The main aim of the present review article was to summarize the current knowledge of COVID-19, such as the transmission process, diagnostic methods, pathological characteristics, potential pathogenic mechanisms and treatment measures.

A review on global threat corona virus disease: COVID-19
Journal of Applied Pharmaceutical Research, 2020
Corona virus disease is a kind of viral disease caused by Severe Acute Respiratory Syndrome-CoV 2, which is first witnessed in Wuhan city, China and it can be transmit from human to human. Coronavirus size ranges from (65-125 nm) in diameter and contain a single stranded RNA as nucleic acid material, size ranging from 26 to 32 kbps in length. The sub group of coronaviruses family is Alpha (α) Beta (β) Gama (γ) and delta (δ) coronavirus. Coronavirus disease is a kind of respiratory disease which mainly affects the lower respiratory tract of human body. Initially interferon α normalisation, broad spectrum antibiotic and antiviral drugs was used to reduce the viral load. There may be different kind of mode of transmission of this virus for example Respiratory transmission, Aerosol transmission, Contact transmission and Hospital acquired transmission. There is a well explained safety measures is provided to inhibit the COVID-19 spread which should be followed properly. There are some testing processes also developed to determine the presence of this virus. Till now not even a single vaccine is developed for the treatment of this COVID-19 but more than 12 countries across the globe are undergoing trial for more than 150 vaccine candidates.

Recently, a novel coronavirus (2019-nCoV-2) associated severe acute respiratory syndrome (SARS-CoV) has emerged in December 2019 in Wuhan, China. This novel coronavirus disease (SARS-CoV-2) is characterized by pulmonary infection and mostly leads to a wide range of clinical manifestations ranging from asymptomatic, mild, and moderate to severe. The severe cases present with pneumonia, which can progress to acute respiratory distress syndrome. Despites the containment measures, the spread of this virus is ongoing. In this review, we highlight the epidemiology, symptoms, transmission, treatment and control, of this fatal disease. It is challenge to global public health therefore, a special attention and efforts to protect or reduce transmission should be applied in susceptible populations including children, health care providers, and elderly people. Public health authorities should also keep monitoring the situation closely, as the more we can learn about this novel virus and its associated outbreak, the better we can respond.
Novel Coronavirus (COVID-19)-A Critical Review
2020
No one has even imagined that infection in the respiratory system in the form of pneumonia because of novel coronavirus (SARS-CoV2) in small town of China, Wuhan during end of December in the year 2019 will come out as an extremely communicable infection. The World Health Organization (WHO) has acknowledged the current epidemic as a threat to whole population worldwide. At present, still we have not reached the advanced levels of research to treat and control this contagious disease. Due to lack of information about the pathogenesis and proliferation pathways of this novel corona virus, whole world is looking forward for its exact prophylaxis. On the basis of recent proofs provided by review and research articles from various gen-uine sources, we tried thoroughly to summarize the various factors regarding COVID-19 like its epidemiology, clinical characteristics, diagnosis, treatment and prevention. Through this review we have made an effort to present a com-mon conceptual literature...
Current Status and Novel Stratergies for Prevention and Treatment of Corona Virus
2020
In early 2020, a new virus began generating headlines all over the world because of the unprecedented speed of its transmission. A novel strain of corona virus — SARS-CoV-2 — was first detected in December 2019 in Wuhan, a city in China’s Hubei province with a population of 11 million, after an outbreak of pneumonia without an obvious cause. The virus officially named SARS-CoV-2 has affected thousands, with a rising death till now over 62,784. The virus has now spread to over 208 countries (Till 5 April 2020) across the globe, and was characterized as a pandemic by the World Health Organization (WHO) on 11 March 2020. The disease caused by an infection with SARS-CoV-2 is called COVID-19, which stands for corona virus disease 2019.

Corona virus disease (COVID-19; Corona virus disease 2019; Previously 2019-nCoV) is an infectious disease caused by a newly discovered corona virus originated from Wuhan in China. COVID-19 is a current worldwide outbreak of disaster in the 21 century. However, the lack of specific drugs to prevent an attack is a major need at this current point of time. Corona viruses are composed of enveloped virions that contain a positive strand RNA genome are characterized by club-like spikes that project from their surface. Human corona viruses may cause the common cold or severe respiratory illness. Corona virus disease spreads primarily through contact with an infected person when they cough or sneeze. It also spreads when a person touches a surface or objects that has the virus on it, and then touches their eyes, nose, or mouth. Social distancing is a non-pharmaceutical infection prevention and control intervention implemented to avoid/decrease contact between those who are infected with a d...
Trending outbreak of corona virus sars-cov-2: a review
International Journal of Molecular Biology
The outbreak of severe acute respiratory syndrome corona virus 2 (sars-cov-2; previously provisionally named 2019 novel corona virus or 2019-ncov) disease in china at the end of 2019 has caused a serious global health issue. It further underwent a worldwide spread, reported to be by human-to-human transmission. As reported by the world health organization (who) globally 1,812,734 positive cases; 113,675 deaths and 456,776 recovered cases have been recorded up to 14 th April, 2020; 2.00am cest due to covid-19. A number of studies are being undertaken to study the possible role and nature of the virus and its impact on human life as a whole. The changing pattern in epidemiology, symptoms and spread or transmission of this virus has made it necessary to carry out further research. Records are suggestive that the viral outbreak has affected more than 200countries/regions globally. Hence it is necessary to know the possible complications, health risk groups, spread, risk factors for mortality, viral shedding, prevention and precautions to be undertaken on individual level to control the outbreak of this pandemic disease.
SARS-CoV-2 Novel Coronavirus: It's Impact and Global Health Concerns
United International Journal for Research & Technology, 2020
COVID-19, the disease caused by SARS-CoV-2, is dangerous and highly contagious disease. Global public health emergency has been declared by the World Health Organisation. This outbreak has caused significant threats to health and economy internationally. Currently, research on SARS-CoV-2 has been going on for vaccine. This virus first originated in China and had a rapid spread to other countries. Severe Acute Respiratory Syndrome (SARS), which has caused pandemic in 2002 has resemblance to nCoV-2019, and we will discuss about that in this paper. WHO has taken many measures to control the propagation of the virus, as a part of it, WHO-established Health Emergency of International Concern (PHEIC), with objectives for public health and impact on global health and economy.
