google了一下： How long is the COVID-19 infectious period? Infectivity can occur 1-3 days before the onset of symptoms. Infected persons can spread the disease even if they are pre-symptomatic or asymptomatic. Most commonly, the peak viral load in upper respiratory tract samples occurs close to the time of symptom onset and declines after the first week after symptoms begin. Current evidence suggests a duration of viral shedding and the period of infectiousness of up to 10 days following symptom onset for persons with mild to moderate COVID-19, and a up to 20 days for persons with severe COVID-19, including immunocompromised persons.
现在的检测能告诉得的是不是omicron, 还是只是positive?

就算还是positive也可以自由活动了么
没有要求复查。
去年感恩节，嗯，前年了，我侄女千里投毒（从学校回家）， 把她爸她妈她妹全部祸祸了，然后爷爷奶奶奇迹般都没事～～
无症状是不是传染性就小？
Positive 和detected 有啥区别？
阳性肯定传染呀！ 想知道痊愈后转阴了的，是否还会传染给别人？多少天以后安全见面？
