A Novel Coronavirus 2019 Linked with Pneumonia in China: Current Status and Future Prospects
The emergence of novel coronavirus strain 2019 (COVID-19) linked with pneumonia poses a serious threat to public health worldwide. Firstly, the COVID-19 was reported in Wuhan, Hubei Province, China in December 2019. Initially, the major proportion of virus-infected cases (i.e. about 99%) was reported in China and now it is being reported in other counties as well. Humans begin to be infected within their communities and transmittance of the viral epidemic increased rapidly due to lack of understanding of its transmission routes and precautionary measures. The existence of COVID-19 in China threatened the population greatly due to the high incidence of fatal respiratory infections. Current investigations speculated that this virus transferred into a human from viral-infected bats. However, the process of interspecies viral transmission is an important scientific question to be addressed. Due to the continuous increase in the patients infected with COVID-19, the World Health Organizat...
The Journal of Infection in Developing Countries
On 31 December 2019 the Wuhan Health Commission reported a cluster of atypical pneumonia cases that was linked to a wet market in the city of Wuhan, China. The first patients began experiencing symptoms of illness in mid-December 2019. Clinical isolates were found to contain a novel coronavirus with similarity to bat coronaviruses. As of 28 January 2020, there are in excess of 4,500 laboratory-confirmed cases, with > 100 known deaths. As with the SARS-CoV, infections in children appear to be rare. Travel-related cases have been confirmed in multiple countries and regions outside mainland China including Germany, France, Thailand, Japan, South Korea, Vietnam, Canada, and the United States, as well as Hong Kong and Taiwan. Domestically in China, the virus has also been noted in several cities and provinces with cases in all but one provinence. While zoonotic transmission appears to be the original source of infections, the most alarming development is that human-to-human transmissi...

Coronavirus Disease 2019 Assosiated Pneumonia in China: Current Status and Future Prospects
The emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) linked with coronavirus disease 2019 (COVID-19) poses a serious threat to public health worldwide.

NOVEL CORONAVIRUS (2019-nCoV): DISEASE BRIEFINGS
Asian Journal of Pharmaceutical and Clinical Research, 2020
Coronavirus (CoV) (2019-nCoV) is a large, enveloped, positive-sense, single-stranded RNA virus. The abnormal outbreak of 2019-nCoV in Wuhan warns of the risk of CoV (2019-nCoV) to public health which causes viral pneumonia outbreak. In our review, we will discuss the biology of CoVs and the potential risk of the novel CoV (2019-nCoV) and guide us to strategic objectives for controlling the virus.

Background: The 2019-nCoV has been identified as the cause of an outbreak of respiratory illness in Wuhan, Hubei Province, China beginning in December 2019. This epidemic had spread to 19 countries with 11791 confirmed cases, including 213 deaths, as of January 31, 2020. The World Health Organization declared it as a Public Health Emergency of International Concern.Methods: A scoping review of 65 research articles published until January 31, 2020 were analyzed and discussed for a better understanding of the epidemiology, causes, clinical diagnosis, prevention and control of this virus. The research domains, publishing dates, journal language, and authors’ affiliations, as well as methodological characteristics were analyzed. All findings and statements that are mentioned regarding the outbreak in this review are based on published information as listed in the references.Results: Most of the publications were in English language (89.23%). The largest proportion of articles were relat...

The 2019-nCoV has been identified as the cause of an outbreak of respiratory illness in Wuhan, Hubei Province, China beginning in December 2019. This epidemic had spread to 19 countries with 11,791 confirmed cases, including 213 deaths, as of January 31, 2020. The World Health Organization declared it as a Public Health Emergency of International Concern. This study analyzed and discussed 70 research articles published until January 31, 2020 for a better understanding of the epidemiology, causes, clinical diagnosis, prevention and control of this virus. Studies thus far have shown origination in connection to a seafood market in Wuhan, but specific animal association has not been confirmed. The reported symptoms include fever, cough, fatigue, pneumonia, headache, diarrhea, hemoptysis, and dyspnea. Preventive measures such as masks, hand hygiene practices, avoidance of public contact, case detection, contact tracing, and quarantines are effective for reducing the transmission. To dat...
