World Health Organization officials are holding a news conference on the coronavirus pandemic on Monday as more countries report cases of new contagious mutations in the virus.
Japan’s National Institute of Infectious Diseases said on Sunday that it had found a new variant of coronavirus in four passengers arriving from Brazil. The institute said the new strain appears to have some of the same qualities, such as increased infectivity, as other variations found in the UK and South Africa.
Meanwhile, the United States has found at least 63 cases of Covid-19 with the new, more contagious strain of the virus first identified in the UK, known as B.1.1.7, the Centers for Disease Control and Prevention said on Friday. The variant does not appear to make patients ill or increase the risk of death, health officials said.
The coronavirus infected more than 90.4 million people worldwide and killed at least 1.9 million people, according to data compiled by Johns Hopkins University.
