1. A #flu 🧵 based on US data from @cdcgov.
Two children died from flu in the week ending Jan. 15, bringing to 5 the total number of pediatric flu deaths so far this season. It's a such a shame to see this feature of flu season return.
2. #Influenza-like illnesses dropped again last week. The further we get out from the holidays, the more likely it is that's a real thing, not an artifact of reporting delays. Is the Omicron wave crowding out flu? Are measures people are taking to avoid Omicron driving down flu?
3. #Influenza-like illness activity (which is #flu, RSV & a range of other non-Covid respiratory pathogens) is incredibly variable this year. It's unusual to see some areas reporting very little (green) & others lots (deep red). In a regular flu season, it's more homogeneous.
4. There isn't as much #flu circulating as in a normal season. What is out there is pretty much exclusively #H3N2, a type of #influenza A virus.
