「ミュー株」国内初確認　空港検疫で２例―厚労省・新型コロナ

　厚生労働省は１日、空港検疫で６月と７月に新型コロナウイルス感染が判明した女性２人から、変異した「ミュー株」が検出されたと発表した。国内での感染確認は初めて。
　ミュー株はコロンビアで１月に初めて報告され、世界保健機関（ＷＨＯ）が８月末に「注目すべき変異株」に分類した。厚労省は感染力の強さなどを詳しく調べる。
　同省によると、２人のうち、４０代女性は６月２６日に成田空港に到着し、アラブ首長国連邦に滞在歴があった。もう１人は５０代で７月５日に羽田空港に到着、英国に滞在歴があった。２人とも無症状だった。（2021/09/01-23:25）

The mu variant of the novel coronavirus has been detected from two women who tested positive for the virus in June and July upon arriving in Japan, the health ministry has said.
   It is the first time for the mutated strain, first reported in Colombia in January, to have been detected in Japan. The World Health Organization late last month classified it as a variant requiring attention. The ministry will investigate details of the variant, including the level of its transmissibility.
   One of the two women, in her 40s, arrived at Narita International Airport in Chiba Prefecture, east of Tokyo, June 26, according to the ministry. She had been to the United Arab Emirates. The other woman, in her 50s, who had stayed in Britain, flew to Tokyo International Airport at Haneda July 5.
   Both women did not show any COVID-19 symptoms.
   Their infections were confirmed after the National Institute of Infectious Diseases, following the WHO's classification of the strain, re-examined genome analysis results of people who had tested positive for the novel coronavirus in quarantine checks at Japanese airports.
