@michaelmina_lab @juli_bg_bs @notdred The observation I think was that Boston had a HUGE spike in wastewater detection (and cases). LA had no such HUGE spike in wastewater but a similarly huge spike in cases. It's an odd disconnect. But as you say (#2), perhaps a calibration issue.
@michaelmina_实验室@juli_bg_bs@没有注意到我认为波士顿在废水检测（和案例）方面有一个巨大的峰值。洛杉矶的废水量没有这么大的峰值，但在案例中也有类似的峰值。这是一种奇怪的分离。但正如你所说（#2），可能是一个校准问题。
