Measles Cases vs. Wastewater Signal

Weekly confirmed measles cases against the national measles wastewater RNA signal, over the window where both are available (Dec 2024 to present). The question is whether wastewater surveillance picks up measles activity the way it does for COVID/flu/RSV. These are two panels sharing one time axis rather than one indexed line, because case counts hit zero in several weeks in this window and a common-base index breaks when the base value is zero. See the full case history (back to 2022) and the full wastewater series.
