social bubble

(名詞/可數) 社交泡沫 - 隨著新冠肺炎 (COVID-19) 封城 (lockdown) 措施逐步解封或放鬆,一小部分獲准相互探視的家人或朋友,如晚輩探視被安頓在長照機構的長輩。

引句:
Under the social bubble proposal, people would be allowed to combine their household with one or two others, up to a maximum of 10 people. A cautious version of the plan would probably mean that the vulnerable such as the over-70s and those with underlying health conditions would be advised to keep isolating and not merge with other households.
