The new coronavirus 2019 (SARS-CoV-2 SARS-CoV-2) is a new type of coronavirus that was discovered in 2019 in Wuhan, China. It causes a disease called covid-19
When it was determined that there was a new virus that caused influenza in Wuhan, there was news that it was the Wuhan virus. This is not what happened, because when other viruses were named after places like Spanish flu or animals like chicken flu or swine flu, behaviors that harmed certain people occurred because of the disease stigma.
Source of the new virus
The source of the viral strain is not known, but there is a possibility that it could be one of the known coronaviruses that infect animals in the first place. As a result of human infection with the virus, it is an adaptation and a disease that is able to cause major problems in the respiratory system, but this is not certain. SARS-CoV-2 has a great genetic similarity with bat corona viruses, and it is possible that bat corona viruses are the origin of SARS-CoV-2 because the virus is similar to a virus found in the Rhinolophus genus of horseshoe bats. Researchers from Guangzhou discovered a sample of pangolins that had a viral DNA sequence that was "99% identical" to SARS. That is why there is a possibility that pangolins were the mediator in the evolution of SARS-CoV-2, which infects humans. The DNA of SARS 2 differs in only one amino acid from the pangolin corona virus.” Pangolins are protected by law in China, but hunting for use in traditional Chinese medicine happens a lot. From a taxonomic perspective, SARS-CoV-2 is classified as a strain. Viruses of severe acute respiratory syndrome coronavirus (SARSr-CoV) ... When the whole genome was conjugated, 92% of the genes were shared between the pangolin coronavirus and SARS-CoV-2, which is not enough to prove that the pangolin is the intermediate host. .
According to the genome sequence known as SARS-CoV-2, the strain was discovered by health authorities within weeks of its appearance in the population in late 2019. Most of the first known cases were on November 17, 2019. The virus then spread to all provinces of China and more than 100 Countries in Asia, Europe, North America, South America, Africa and Oceania. Person-to-person transmission of the virus has been confirmed in all of these regions. On January 30, 2020, the World Health Organization declared SARS-CoV-2 a public health emergency, and on March 11, 2020, the World Health Organization declared it a global pandemic.
The SARS-CoV-2 virus has mutated, one of which was in a mink.
The spread of the Corona virus 2019 like any virus that causes a cold; Air contaminated with the virus, respiratory secretions. .️
