Influenza-Like Illness (ILI) continues to track lower than the mild 2015-16 season.
Still not enough flu for CDC to run its hospitalization model.
Still just one U.S. pediatric flu death this season.

This is so important. If you're over 65 (or under but medically high risk) and test positive GET THE ANTIBODY DRIP. If your doctor doesn't know anywhere to get it, call hospitals/infusion centers around town until you find it. This is ridiculous.
This is who qualifies for the antibody infusion: Image
For my local friends, we have a large antibody infusion center now at Washington Hospital Center! Spread the word.

NATURE: "We tested 690 respiratory samples from the 129 patients for the presence of infectious virus using cell culture and determined the viral RNA load with RT-qPCR (Fig. 1). Infectious SARS-CoV-2 was isolated from 62 respiratory tract samples (9.0%) of 23 patients (17.8%)." Image
"The median time of infectious virus shedding was 8 days post onset of symptoms (IQR 5–11, range 0–20) and probit analysis showed a probability of ≤5% for isolating infectious SARS-CoV-2 when the duration of symptoms was 15.2 days (95% CI 13.4–17.2) or more." Image
"The median viral load was significantly higher in culture positive samples than in culture negative samples (8.14 versus 5.88 Log10 RNA copies/mL, p < 0.0001) and the probability of isolating infectious SARS-CoV-2 was less than 5% when the viral load was below 6.63."
