Geneva:There is no evidence to suggest that the newly-detected Japanese mutation made the coronavirus more aggressive, World Health Organisation (WHO) Director-General Tedros Adhanom Ghebreyesus said on Monday.
On Sunday, Japan's National Institute of Infectious Diseases reported detecting a new variant of the coronavirus in four people who arrived from Brazil.
"Over the weekend, the WHO was notified by Japan about a new variant of the virus. The more the virus spreads, the higher the chance of new changes to the virus," Tedros said at a daily briefing, adding that "at present, the variants do not seem to show increased severity of the disease."
