A novel Coronavirus / COVID-19, has been identified as the cause of an outbreak of respiratory illness.

Here in our knowledge center, you can find the most recent research articles and news related to this outbreak collected from our current resources.

1- COVID-19 (Novel Coronavirus) 

Severe acute respiratory disease (known as COVID-19) caused by a novel coronavirus (provisionally called 2019-nCoV) first identified in December 2019 in Wuhan, Hubei Province, China

  • initial infections associated with seafood and animal market 

  • human to human transmission confirmed through route and ease of transmission are unclear

  • 2019-nCoV is a member of the beta genus coronaviruses and closely related to SARS-CoV

    • 88% homology reported to bat SARS-like coronavirus virus (China CDC Weekly 2020 Jan 22)

    • International Committee on Taxonomy of Viruses provisionally designates novel coronavirus as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (bioRxiv 2020 Feb 11)

  • common signs of COVID-19 include fever, cough, and shortness of breath.

  • there is no specific antiviral treatment for 2019-nCoV, but supportive care may help to relieve symptoms and should include support of vital organ functions in severe cases.

2- Clinical findings in a group of patients infected with the 2019 novel coronavirus (SARS-Cov-2) outside of Wuhan, China: retrospective case series.



To study the clinical characteristics of patients in Zhejiang province, China, infected with the 2019 severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) responsible for coronavirus disease 2019 (covid-2019).


Of the 62 patients studied (median age 41 years), only one was admitted to an intensive care unit, and no patients died during the study. According to research, none of the infected patients in Zhejiang province were ever exposed to the Huanan seafood market, the original source of the virus; all studied cases were infected by human-to-human transmission. The most common symptoms at the onset of illness were fever in 48 (77%) patients, cough in 50 (81%), expectoration in 35 (56%), headache in 21 (34%), myalgia or fatigue in 32 (52%), diarrhea in 3 (8%), and haemoptysis in 2 (3%). Only two patients (3%) developed shortness of breath on admission. The median time from exposure to onset of illness was 4 days (interquartile range 3-5 days), and from onset of symptoms to first hospital admission was 2 (1-4) days.

4- COVID-19 in the Shadows of MERS-CoV in the Kingdom of Saudi Arabia

Abstract :

Middle East Respiratory Syndrome Coronavirus (MERS-CoV) has plagued the Middle East since it was first reported in 2012. Recently, at the end of December 2019, a cluster of pneumonia cases were reported from Wuhan city, Hubei Province, China, linked to a wet seafood market with a new coronavirus identified as the etiologic agent currently named SARS-CoV-2. Most cases are in Mainland China with international spread to 25 countries. The novelty of the virus, the rapid national and international spread, and the lack of therapeutic and preventative strategies have led the WHO International Health Regulation emergency committee to declare the disease as a Public Health Emergency of International Concern (PHEIC) on January 30, 2020. As it relates to countries with the ongoing MERS-CoV community cases and hospital-acquired infections, there will be a huge challenge for HCWs to deal with both coronaviruses, especially with the lack of standardized and approved point of care testing. This challenge will now be faced by the whole global health community dealing with COVID-19 since both coronaviruses have a similar presentation. Those patients should now be tested for both MERS-CoV and SARS-CoV-2 simultaneously, and with the continuing wide international spread of SARS-CoV-2, the travel history to China in the last 14 days will be of less significance.

6- Characteristics of COVID-19 infection in Beijing.


Since the first case of a novel coronavirus (COVID-19) infection pneumonia was detected in Wuhan, China, a series of confirmed cases of the COVID-19 were found in Beijing. We analyzed the data of 262 confirmed cases to determine the clinical and epidemiological characteristics of COVID-19 in Beijing.

By Feb 10, 2020, 262 patients were transferred from hospitals across Beijing to the designated hospitals for special treatment of the COVID-19 infected by Beijing emergency medical service. Among 262 patients, 46 (17.6%) were severe cases, 216 (82.4%) were common cases, including 192 (73.3%) mild cases, 11(4.2%) non-pneumonia cases, and 13 (5.0%) asymptomatic cases respectively. The median age of patients was 47.5 years old and 48.5% were male. 192 (73.3%) patients were residents of Beijing, 50 (26.0%) of which had been to Wuhan, 116 (60.4%) had close contact with confirmed cases, and 21 (10.9%) had no contact history. The most common symptoms at the onset of illness were fever (82.1%), cough (45.8%), fatigue (26.3%), dyspnea (6.9%), and headache (6.5%). The median incubation period was 6.7 days, and the interval time between illness onset and seeing a doctor was 4.5 days. As of Feb 10, 17.2% of patients have been discharged and 81.7% of patients remain in hospital in our study, the fatality of COVID-19 infection in Beijing was 0.9%.

This document is intended for clinicians taking care of hospitalized adult and pediatric patients with a severe acute respiratory infection (SARI) when a nCoV infection is suspected. It is not meant to replace clinical judgment or specialist consultation but rather to strengthen the clinical management of these patients and provide up-to-date guidance. Best practices for SARI including IPC and optimized supportive care for severely ill patients are essential.
