Corona Virus in Detail

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a virus closely related to the SARS virus. The disease first emerged in Wuhan, China and is the cause of the 2019–20 coronavirus outbreak.Those affected may develop a fever, dry cough, fatigue, and shortness of breath. A sore throat, runny nose or sneezing is less common. While the majority of cases result in mild symptoms, some can progress to pneumonia and multi-organ failure. The case fatality rate is estimated at between 1% and 5%.

The infection is spread from one person to others via respiratory droplets produced from the airways, often during coughing or sneezing. Time from exposure to onset of symptoms is generally between 2 and 14 days, with an average of 5 days.The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab or sputum sample. Antibody assays can also be used, using a blood serum sample, with results within a few days. The infection can also be diagnosed from a combination of symptoms, risk factors, and a chest CT scan showing features of pneumonia.

Hand washing, maintaining distance from other people, and not touching one's face with unwashed hands are measures recommended to prevent the disease. It is also recommended to cover one's nose and mouth with a tissue or a bent elbow when coughing. Masks are recommended for those who suspect they have the virus, and for those who are taking care of someone with a suspected infection, but not for the general public. There is no vaccine or specific antiviral treatment, with management involving treatment of symptoms, supportive care and experimental measures.

The World Health Organization (WHO) has declared the 2019–20 coronavirus outbreak a Public Health Emergency of International Concern (PHEIC). As of 7 March 2020, evidence of local transmission of the disease has been found in multiple countries across all six WHO regions.
