A novel coronavirus has been reported as the causative pathogen of the Coronavirus disease 2019 (COVID-19) outbreak in Wuhan city, China in December 2019. Due to the rapid spread of the virus worldwide, it has been announced as a pandemic by the World Health Organization (WHO). Hospitalized patients in Wuhan were associated with the Huanan seafood wholesale market where live animals, such as poultry, bats, snakes, frogs, rabbits, marmots, and hedgehogs are sold in that market which suggests a possible zoonotic infection. It was suggested that bat is the natural host of SARS-CoV-2, but the intermediate host is still unclear. It is essential to identify the potential intermediate host to interrupt the transmission chain of the virus. Pangolin is a highly suspected candidate as an intermediate host for SARS-CoV-2. Recently, SARS-CoV-2 infection has been reported in cats, dogs, tigers, and lions. More recently SARS-CoV-2 infection affected minks severely and zoonotic transfer with a variant SARS-CoV-2 strain evidenced in Denmark, Netherlands, USA, and Spain suggesting animal-to-human and animal-to-animal transmission within mink farms. Furthermore, experimental studies documented the susceptibility of different animal species to SARS-CoV-2, such as mice, golden hamsters, cats, ferrets, non-human primates, and treeshrews. It is also essential to know the possibility of infection for other animal species. This short review aims to provide an overview on the relation between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and animals.

The World Health Organization (Who) In March 2020 Declared Covid 19 A Pandemic, Due To The  Global And Rapid Spread Of A Novel Coronavirus (Who, 2020). The Covid 19 Pandemic Being Highly Infectious And Unpredictable, Has  Disrupted  Social, Economic, Environmental And Political Spheres Of Life. Globally, People Have Ventured Into A “Lockdown World”, Increasing Uncertainty About Their Future Amidst The Covid 19 Pandemic. As A Result Of The Pandemic, Social Alteration Has Taken The Form Of Social Distancing, Self-Isolation And Self-Quarantine.  Many Were Unprepared For The Shift From The “Normal”, Propelling  Undue  Stress Under The New Normal Way Of Doing Things During The Current Global Pandemic Crisis. This Has Been Accompanied By Social, Emotional And Mental Effects, As The Ongoing And Fluid Nature Of The Pandemic Has Created Uncertainty For Many People. The Covid 19 Pandemic, As A Multidimensional Stressor Affecting Wellbeing, Has Affected Individuals, Families, Educational, Occupational, And Broader Societal Systems.

In December 2019, several cases of pneumonia caused by a novel Coronavirus, later identified as SARS-CoV-2, were detected in the Chinese city of Wuhan. Due to its rapid, worldwide spread, on 11 March 2020 the World Health Organization declared a pandemic state. Since this new virus is genetically similar to the coronaviruses of bats, it was thought to have a zoonotic origin. Within a year of the appearance of SARS-CoV-2, several cases of infection were also reported in animals, suggesting animal-to-human and animal-to-animal transmission within mammals. Natural infection has been found in both companion and captive animals such as lions, tigers and gorillas. Among farm animals, the only ones found to be susceptible to SARS-CoV-2 infection so far are minks. Experimental infections have documented the susceptibility to SARS-CoV-2 of several animal species, such as humanized mice, hamsters, cats, dogs, ferrets, racoon dogs, cattle and non-human primates. Experimental infections are crucial for both elucidation of the role of animals in transmission and development of appropriate animal models for pathogenesis and therapy studies. This review aims to update the knowledge on natural and experimental SARS-CoV-2 infections in animals.

The December 2019 outbreak of pneumonia in Wuhan, Hubei Province of China was rapidly linked to a novel coronavirus 2019-nCoV. The rapid spread and severity of the virus has led the World Health Organization to declare it a Public Health Emergency of International Concern. We recently described the first homology models of the main 3CL protease from 2019-nCoV, and now present models of the other viral protease, the papain-like protease or PLpro. Whilst the overall viral genome is most closely associated with bat coronaviruses, no bat PLpro crystal structures are known. Wuhan 2019-nCoV PLpro is most closely related to a bat coronavirus PLpro (97% identity), then SARS (80 %) and MERS (29%) and the most promising models presented here are prepared from SARS crystal structure templates.

Abstract The world is battling out the pandemic of Covid-19. The World Health Organization (WHO) is jointly acting upon the same daily, which is evident from the ‘situation reports.’ The pandemic, which saw its origin in Wuhan, has spread across the world within a short span of under two months. While the pandemic has effectively instilled a situation of cordon sanitaire across the globe, the virus seems to show no respite. This study collates different sources and establishes the human tendency of knowledge hiding as the prime reason for the spread of such colossal magnitudes. The study underlines the notion by examining some of the critical cases and situations that have unfolded in the very recent past.

World Health Organization (WHO) announced the official name of the 2019 novel coronavirus associated diseases coronavirus disease (COVID-19) and the reference name for the virus is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Transmission of SARS CoV-2 in humans occurs mainly via respiratory droplet or aerosols, close contact with an infected person, exposed to coughing, sneezing and likely in oral-faecal. The COVID-19 outbreak started in different countries at different times, and now those countries are at different stages. By comparing infection trajectories from the 100th case mark, we have been able to observe the rapid spread of the virus in various countries. To date, no specific antiviral drugs or vaccines are available for the control of SARS CoV-2. The experts at global level suggest implementation of strict measures such as practicing quarantine, social distancing, avoiding social gathering to reduce the number of COVID-19 cases. This is a dynamically unfolding pandemic that will require the concerted efforts of counties around the world to control. Given the unfold of the new coronavirus and its impacts on human health, it becomes pertinent to device methods for handling this public health emergency at the community, national, and international levels. it's vital to additional investigate a preventative intervention to halt the unfold of the COVID-19 infection, because it has been discovered that not all countries have constant fate concerning infection and fatality. It becomes vital to acknowledge and study the factors accountable and also the underlying mechanisms for this.

Since the outbreak of the novel Coronavirus in December 2019 in Wuhan China, this novel Coronavirus disease(COVID-19) has spread worldwide taking not only epidemic proportions but with its rapid spread world health organization(WHO) was forced to declare it as a pandemic. The Severe Acute respiratory syndrome (SARS)-Coronavirus (CoV2) virus is responsible for clusters of severe respiratory illness that simulates acute respiratory syndrome that was what was initially. It is thought although that it is equivalent to the high altitude pulmonary oedema (HAPE), showing glass ground opacities in lungs. More experience is getting acquired with changes in treatment approaches from PEEP to avoid intubation and just ensure oxygen levels maintained. Human to human transmission through droplets, contaminated hands as well as surfaces, has been revealed with an incubation period varying from 2-14 days. Early diagnosis using reverse transcription polymerase chain reaction (RT-PCR) or computed tomography (CT) scan chest, quarantine, as well as supportive treatment are necessary for getting a cure. In this review we have tried to analyze the epidemiology, diagnosis, isolation, and treatment, including antiviral drugs like remdesivir, favipiravir, chloroquine and hydroxychloroquine, corticosteroids, antibiotics, and ivermectin. With 3 successful cases of convalescent plasma achieved in USA, trials going on in India along with vaccines are also detailed in this article.

Introduction: In December 31, 2019, China gave bad news the World Health Organization (WHO) throughtout an outbreak of a mysterious pneumonia characteristic in Wuhan, which is located in Hubei Province with 11 million people. On 1 January 2020, the source of the Coronavirus outbreak is a seafood market that has been closed. The Huanan Seafood Wholesale Market in Wuhan City, where the virus was first detected, fit that description to a tee, with vendors illegally trading in wild and exotic animals alongside the daily ocean catch. Discussion: This literature review retrieved the articles from databases such as Springer, PubMed, and Google Scholar. The articles on preventing were 17 articles and curbing were 15 articles. The literatur review is a critical and in-depth evaluation of previous research to obtain important information about the dangers of the corona virus and the important of preventing and curbing the corona virus. Guidance regarding personal protective equipment in infection prevention and control is provided by WHO. Goggles and face shield must always be used to protect against potential hazards, and health workers don’t touch mucous membranes (eyes, nose or mouth). Conclusion: Recommendations for preventing health and preventing Covid19 are: limiting physical contact or being in a room with people without symptoms, covering the mouth with a tissue when sneezing or coughing and then throwing the tissue into the trash. If there are no tissues, use your sleeves to avoid liquids or droplets on other people or sticking to nearby objects, do not travel to the red zone against the spread of Covid19, rub hands properly for 20 seconds with soap and water, If it is quite difficult to find water, it is advisable to always have a Hand Sanitizer with an alcohol content of at least 60% which is believed to be able to kill germs. Recommendation for curbing the spread the Covid19 include: lockdown, stay at home, and physical inactivity.
