This variation may have originated in Wuhan, China and caused milder infections than others.
According to Reuters, Singapore researchers have discovered a new variant of SARS-CoV-2, causing milder infections in people with Covid-19. This result is published in the medical journal The Lancet.
Research shows that people infected with the new variant of SARS-CoV-2 have better clinical results, requiring less special care. The authors also showed that the new variant had a part of the gene deleted, creating a stronger immune response.
The variant may have come from Wuhan, China, discovered in the patient cluster recorded from January to March. In Singapore, this variant was infected through many clusters before being discovered and controlled.
The study was attended by a team of Singaporean experts from the National Infectious Diseases Center (NCID), Duke-NUS School of Medicine and the Center for Science, Technology and Research.
Gavin Smith, Duke-NUS School of Medicine, said: “These studies provide the first reliable data on genetic changes (mutations) in SARS-CoV-2 and how they affect severity. of the patient ”.
The discovery of a new variant of SARS-CoV-2 also has implications for vaccine development and the treatment of Covid-19.
Previously, Malaysia and the Philippines found D614G strain of SARS-CoV-2 with the rate of infecting other individuals 10 times higher than that of virus causing the first outbreak.
According to Dr Paul Tambyah, National University Hospital of Singapore, this news shows that “the virus tends to be less virulent to infect more people”. They do not kill the host but find a way to adapt, depend on for “food”, where to live.
