Despite being nearly 10 months into the COVID-19 (coronavirus disease 2019) pandemic, definitive animal host for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), causal agent of COVID-19, remains unknown. Unfortunately, similar problems exist other betacoronaviruses, and no vouchered specimens to corroborate species identification most these pathogens.

There is a dangerous virus spread across the globe since end of 2019. The virus's name Coronavirus disease (Covid-19). (COVID-19) an infectious caused by newly discovered coronavirus. COVID-19 one virus, called severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2. An epidemic 2019 outbroke in December China, Wuhan, which becoming Public Health Emergency International Concern.

Coronavirus (COVID-19) was first seen in late December Hubei province of Wuhan city China. The highly contagious disease, caused by a virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is transmitted from humans to humans. After the case Wuhan, disease rapidly spread other parts globe.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmissible and pathogenic coronavirus that emerged in late 2019 and has caused a pandemic of acute respiratory disease, named ‘coronavirus disease 2019’ (COVID-19), which threatens human health and public safety.Hydroxychloroquine (HCQ) is an anti-malaria drug; its antiviral properties are controversial,and some in vitr...

Advanced age has repeatedly been identified as an independent correlate of adverse outcome and a predictor of mortality in cases of severe acute respiratory syndrome (SARS). SARS-associated mortality may exceed 50% for persons aged 60 years or older. Heightened susceptibility of the elderly to severe SARS and the ability of SARS coronavirus to replicate in mice led us to examine whether aged mi...

The temporal and spatial distributions of the 2003 severe acute respiratory syndrome (SARS) outbreak in Amoy Gardens of Hong Kong was reexamined using all confirmed cases. The outbreak actually extended to nearby residential complexes. Airborne spread was the most likely explanation, and the SARS coronavirus could have spread over a distance of 200 m.

ABSTRACT There have been many laboratory-based investigations since the emergence of the novel coronaviruses in the autumn of 2012, but most of the parameters required for establishing scientifically the control measures that will protect against them have yet to be determined. Equally, the global distribution of the viruses in their animal reservoir has yet to be established. The experience of...

In early April 2003, severe acute respiratory syndrome (SARS) was diagnosed in a Pennsylvania resident after his exposure to persons with SARS in Toronto, Canada. To identify contacts of the case-patient and evaluate the risk for SARS transmission, a detailed epidemiologic investigation was performed. On the basis of this investigation, 26 persons (17 healthcare workers, 4 household contacts, a...
