Earlier in December 2019, a novel extreme coronaviral syndrome 2 (SARS-CoV-2) outbreak of coronavirus 2019 (COVID-19) occurred in Wuhan, Hubei Region, China. The World Health Organisation announced the epidemic as an international disaster in public health on 30 January 2020. As of 14 February 2020, there were 49,053 laboratory-confirmed fatalities and 1,381 deaths worldwide. Many governments have become at risk of contracting illness after implementing a series of prevention steps. We performed a literature review of resources accessible to the public to synthesise pathogen and emerging disease awareness. This literature review analyses the causative cause, pathogenesis and immune reactions, epidemiology, detection, care and managing methods for the epidemic, regulating and preventing.

Viruses are Submicroscopic infectious agents that replicate and grow only inside the living cells of an organism. These viruses are important especially when they are capable of infecting humans. Such diseases are called zoonoses. Viral zoonoses include Lassa fever, Ebola fever,SARS,Avian flu etc.The aim of this study is to present a short review of recent literature available on animals as reservoirs for human viruses. A detailed study is done by reviewing several articles on animals as reservoirs for human viruses. Thorough search of articles was carried on the databases Pubmed and Google scholar.Viruses continue to be a major threat in both endemic and pandemic forms.Early diagnosis and treatment plan to be implemented, as it continues to be a major health threat and becomes worse day-by-day. Hence Knowledge and awareness needs to be initiated and implemented.

The coronavirus disease (COVID-19) is a highly transmittable and viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which arises in Wuhan, China and spreads all around the world. The Genomic analysis shows that SARS-CoV-2 is related to severe acute respiratory syndrome- like (SARS-like) bat viruses, so bats could be the possible primary reservoir for this disease. The intermediate source of origin is not known, the rapid human to human transfer has been confirmed largely. Most adults or children with COVID-19 infection are with mild flu-like symptoms and a few patients are in critical condition and develop acute respiratory distress syndrome, respiratory failure, multiple organ failure, even death of the individuals. The most commonly reported Symptoms are fever, cough, myalgia or fatigue,pneumonia, and complicated dyspnea,where's less common reported symptoms include headache, diarrhea, halmoprysis, runny nose, and phlegm producing a cough. Still There is no clinically approved antiviral drug or vaccine available for COVID-19.Few broad-spectrum antiviral drugs have been evaluated against COVID-19 in clinical trials, resulting in clinical recovery. The current review is about the history of covid 19.

The COVID - 19 pandemic is also known as coronavirus pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The outbreak was first identified in Wuhan, China, in December 2019. The source is probably from bats and possibly via pangolins. The virus is primarily spread between people during close contact, most often via small droplets produced by coughing, sneezing and talking. Common symptoms include fever, cough, shortness of breath and loss of sense of smell. Complications include pneumonia and acute respiratory distress syndrome. The time from exposure to onset of symptoms is typically around 5 days and ranges from 2 to 14 days. Prevention is by washing hands frequently, cleaning the surfaces, wearing face masks, self isolation and social distancing.
