As we know, the SARS-COV-2 virus causes Covid-19 to begin in Wuhan (China) in December 2019 but the recent research of Italian scientists shows, most likely this virus Has appeared in Lombardy region, northern Italy in the summer of 2019.02: 00/3: 45 South Milan researchers and the National Institute of Italy National Health Tested 435 samples and urine samples of 156 diseases Multiplication is rash on the skin like measles from the summer of 2019. The result shows that a total of 13 patients have a positive sample with SARS-COV-2. The study was sent to the Lancet Medical Journal last week and awaits the first sample of the test results positive for the genetic material of SARS-COV-2 as a urine sample collected On September 12, 2019, from an 8-month-old baby. Scientists discovered that some mutations of SARS-COV-2 virus were first reported in January 2020 present strains in northern Italy in October 2019
. (Source: AFP) "Our research provides strong evidence that SARS-COV-2 most likely has appeared in Northern Italy at the end of the summer of 2019 and shows a clear relationship between the expression On the skin like measles and SARS-COV-2 ". However, the scientific gender said that the evidence of infection is still incomplete to accurately conclude that these patients have Covid-19 or No. Another remarkable discovery in the study of Italy scientists is most likely many variants of SARS-COV-2 viruses that have appeared before the pandemic occurred
Research results confirmed that Some SARS-COV-2 series spread worldwide at least in several weeks before the first Covid-19 cases were reported. Based on tested evidence, scientists discovered So some mutations of the SARS-COV-2 virus were first reported in January 2020 present in the strains in northern Italy in October 2019. Research also shows that the virus line This basically Unlike the first line in Wuhan (Hubei Province, China) in December 2019, then spread to the world. According to the Italian scientists, the study could be visualized. Virus mutations may have developed parallel outside China and appear in different geographic areas. A hidden epidemiologist living in Beijing (China) said, the study of the The Italian scientist contributed to strengthening the hypothesis that SARS-COV-2 could originate and develop in different regions of the world before the first outbreak reported in Wuhan. "This is the reason for scientists around the world to check freezers, blood banks and other sample repositories to find traces about the origin of SARS-COV-2", and affirming, Such studies have brought surprising discoveries about SARS-COV-2. Nature Nature reported, in November 2020, scientists discovered relatives of SARS-COV-2 virus in nail bats Cambodia's Shamel's horse was arrested in 2010, as well as in frozen bats from Japanese horseshoe bats collected in 2013. This findings show that the relatives of SARS-COV-2 viruses most likely Popularly in horseshoe bats living outside China. However, multi-origin hypothesis also makes the scientific gender wondered by the question if the virus has circulated in many other regions in the world, why not Outbreaks like epidemics in Wuhan? The ability is that the initial SARS-COV-2 strains cannot be transmitted through people as some mutant mutations later
Experts explain, can virus SARS-COV- 2 tried to infect naturally into people for years, if not to say for decades. And after many errors testing, it finally accumulated appropriate characteristics and suddenly infects people. A hidden epidemiologist said: "There are still many questions around The origin of the SARS-COV-2 virus, and I hope many scientists from other countries can be meticulous and bravely check the collected samples to contribute to finding the answer ".
