New Coronavirus Variant found in travellers from Brazil

New coronavirus strains have been identified in four travelers from the Brazilian state of Amazonas, Japan’s Ministry of Health said on Sunday, in a recent case of the virus.
A department official said a study was being conducted on the effectiveness of different vaccines, different from the highly contagious varieties found for the first time in Britain and South Africa that led to an increase in cases.

“Currently, there is no evidence that new mutations in Brazil are contagious,” Takaji Wakita, head of the National Institute of Infectious Diseases, told a Department of Health forum. Of the four passengers who arrived at Tokyo’s Haneda airport on January 2, a 40-year-old man had trouble breathing, a 30-year-old woman had a headache and a sore throat and a young man had a fever, and a young woman showed no symptoms, the health department said.

A total of 289,000 cases have been reported in the country, killing 4,061 people, said NHK community broadcaster.
