Global news and updates about the outbreak and global spread of the Corona Virus, COVID-19, SARS CoV 2 Worldwide.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), colloquially known as the coronavirus and previously known by the provisional name 2019 novel coronavirus (2019-nCoV) is a positive-sense single-stranded RNA virus. It causes coronavirus disease 2019 (COVID-19), a respiratory illness. SARS-CoV-2 is contagious in humans, and the World Health Organization (WHO) has designated the ongoing pandemic of COVID-19 a Public Health Emergency of International Concern. The strain was first discovered in Wuhan, China, so it is sometimes referred to as the “Wuhan virus” or “Wuhan coronavirus”. Because the WHO discourages the use of names based upon locations and to avoid confusion with the disease SARS, it sometimes refers to SARS-CoV-2 as “the COVID-19 virus” in public health communications. The general public frequently calls both SARS-CoV-2 and the disease it causes “coronavirus”, but scientists typically use more precise terminology.
The virus is mainly spread between people during close contact, often via small droplets produced during coughing, sneezing, or talking. While these droplets are produced when breathing out, they usually fall to the ground or surfaces rather than being infectious over large distances. People may also become infected by touching a contaminated surface and then their face. The virus can survive on surfaces for up to 72 hours. Coronavirus is most contagious during the first three days after onset of symptoms, although spread may be possible before symptoms appear and in later stages of the disease.
