Japan’s National Institute of Infectious Diseases in Tokyo (NIID) reported detecting a new mutant strain of the new coronavirus in four travelers arriving from Brazil to Tokyo on January 2.


The Brazil Ministry of Health says passengers disembarked in the Japanese capital on January 2, after a season in Amazonas, developed mild symptoms and were quarantined at Tokyo airport.

According to information supplied to the Ministry of Health by the Japanese health authorities, the new variant has 12 mutations, one of which is the same found in variants already identified in the United Kingdom and South Africa, which implies a greater potential for transmission of the virus. However, there is no scientific evidence that points to an impact on the effectiveness of laboratory diagnosis or vaccines under study currently against Covid-19.
