Flu Overview update.
A month ago we detected flu in less than 10% of samples.
In the most recent batch over 50% had FluA (H1N1 and/or H3N2) and 75% had FluC.
Numbers were low, but flu season is starting.

What should we expect this flu season?
Here’s a forecast from a wastewater perspective (because sh*t don’t lie)

As expected, vaccine-derived antibodies show reduced effect against the K variant.
But, preliminary real-world data shows that the vaccine is protecting against severe disease.

In the century leading up to 1975, nearly 6000 freighters went down in the Great Lakes.
The Edmund Fitzgerald was the last.
The last. In 50 years, not a single commercial freighter has been lost in the Great Lakes.
Why?
It's NOAA. Of course it's NOAA.
