@covid_wastewater I clicked on the "source data" link and it shows MA as very low on the map. Why is it very high on your summary? Different date of processing the source?
@nosrednayduj Confusing Web page layout.
That map is actually a tab, showing "Influenza A" by default.
Tapping "COVID-19" above the heading for the map shows MA high.
@neilvandyke @nosrednayduj Yes, but I now see that there’s a unique URL for that tab, so I’ve changed the source data URL to point to that instead. So, yay, I’m glad you asked!
@covid_wastewater Sure, but--hearing of many, many cases at my university in Philadelphia. Staff at the nearby pharmacy told me they're also seeing a lot of flu.
