Novel coronavirus (SARS-CoV-2)
October 20, 2021
Severe acute respiratory syndrome coronavirus 2: SARS-CoV-2, formerly used by the World Health Organization is coronavirus. The 2019 novel coronavirus (2019-nCoV) and the casual name used when the disease caused by the virus began to spread is "Wuhan corona virus" or "Wuhan pneumonia" (Simplified Chinese: 武汉冠状病毒; ). Traditional Chinese: 武漢冠狀病毒) is a contagious virus that causes respiratory infections. which is the cause of the coronavirus disease 2019 (COVID-19) outbreak in 2019–2020. Genome sequencing shows that It is a single-stranded RNA virus. with a sequence of genetic material like MRNA (Positive-sense single-stranded RNA virus) The first suspected case was reported to the World Health Organization on December 31, 2019. The first case of illness appeared three weeks earlier, when On December 8, 2019, the virus was genome sequenced after a nucleic acid test in a positive patient sample in a patient with pneumonia. During the 2019–2020 coronavirus outbreak, many early cases were linked to large markets selling seafood and animals. And the virus is believed to have an animal origin. Comparisons of the genetic sequence of this virus and other virus samples have shown similarities with SARS (79.5%) and bat coronavirus (96%), making it the most probable origin in bats.
