The virus that Vietnam isolated on Covid-19 cases coming from Europe was found to be different from the one on patients found in Asia, the newspaper quoted Le Thi Quynh Mai, deputy director of the county's National Institute of Hygiene and Epidemiology, as saying.
The institute's study has yet to show which of the two groups is more infectious as the spread of the virus also depended on the environment, geography and people infected, while detecting the changes of the virus would aid vaccine production, she was cited as saying.
