1. @CDCgov has been told of 4 more children who died from #flu this season, bringing the 2022-23 total to 115 so far. There have been years with a higher pediatric death toll, but it's tragic to see so many kids die from flu. No word on their vaccination status. (Graph = mine)

2. @CDCgov's latest FluView report, out today, reports that #flu activity is low in most parts of the country. In the few places where it isn't low, it has declined from the previous week. It remains to be seen if flu season is effectively over or if there's more to come.
3. Oddly, though, the epi curve has not yet slipped below the epidemic threshold. Strange to see it skip along just above the threshold for 5 weeks running.
1. #Flu activity is at low levels now in most of the country, but the percentage of visits to health providers that are for flu-like illnesses is still limping along just above the epidemic threshold level for the 4th week in a row.

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.
1. A sure fire sign #flu is making a comeback: 2 children in the US have died from flu this month. They are the first to die from flu in over a year. Last year there was 1 pediatric flu death, in the week ending Nov. 28, 2020.
Sad to see new additions to this graph.

2. There've been lots of ugly graphs in the past couple of years, but the pediatric flu deaths one from the @CDCgov's weekly FluView report has been a respite from them. The collapse of flu activity in the earlier days of the pandemic meant no kids dying from flu. Changing now.
1. Short #flu thread.
@CDCgov's FluView came out today; data for the week ending Nov 27.
US Flu activity is ticking up. It's still not near most non-pandemic years, but flu is returning. 1.5% of clinical flu tests were positive, compared to .02% in 2020.

2. The data behind this chart give you a sense of the steady rise in flu positivity. In a pre-Covid year, you might expect to see a positivity rate of 4%, 8% or higher at this time of the #flu season, depending on whether the season was getting off to an early start or not.
3. So looking at the influenza-like illness curves, you can see that ILI rates (they include illnesses that are not #influenza) appear to be approaching the point where they cross the threshold into ILI season. But how much of that is flu?
