Re: USA - Actual ISDS flu trends

Thank You, GSGS!

What is the time frame where a wave of influenza is considered a "spring wave?" and does it have to begin before a particular week or end after "official" flu season?

Re: USA - Actual ISDS flu trends

Louisiana:

Dr. Frank Welch, Medical Director for Louisiana's Immunization Program:

-Unusual season

-Flu problem extraordinary this year

-Maximum level, which is called 'widespread', for about three to four weeks now

-Season has also produced a number of different strains of flu

-Tough to predict when it'll peak

-It wouldn't be surprising to me if there was a new type that started coming in and we see another peak coming up in the next couple weeks

Perhaps a mutated pH1N1 that has evaded the immunity from last season and might end up being Tamiflu resistant?

Dr. Welch is getting it. I just don't understand how people in positions at the state and federal level could miss all the indicators that are out there. They certainly have access to the same information most of us do and they can easily come here to get it. It's eerie how little attention is being given to this potential disaster. The tiger is crouched in the brush on the side of the road. People like us see it and are shouting while public health officials and polititians continue to saunter down the road oblivious of what is about to happen. Where are the school closure plans (I mean real closings - not over-the-weekend-bleach-all-the-doorknobs type closing). God forbid we should be inconvenienced by school closings and cancellation of large public events. And think of what it would do to the economy. It's like they are just pretending like this is just another flu season and hoping it goes away. Sorry - rant finished.

most regions are still going up with same speed as the weeks before


NYC: still down, no sign of a reversal
Connecticut is similar to New York, but now seems to go up again
New Jersey,New York State are still going down, but at lower speed
than they went up
Florida and Georgia, also up again into the already declining trend
Tennessee still down (since late Dec.)

Utah,Boston : double-peak ?

explosive up in region VI


US-peak in week 6, I guesstiate

Re: USA - Actual ISDS flu trends

Louisiana has been hit hard with Influenza B. By week 52, 80% of positive influenza samples were Influenza B. Week 2, "...88% of all subtyped positives reported this week from sentinel sites are type B." Week 3, "...66% of all subtyped positives reported this week from sentinel sites are type B." The first PCR detection of 2009 A(H1N1) was noted in week 3.

Although there is an overall downward trend in many states, pH1N1 is just getting started and the serious cases and deaths are increasing with it. I don't expect a peak for pH1N1 until maybe Week 8 in Regions 2, 3 and 4 and possibly as late as Week 10 in Regions 5, 7, 8, and 10. The rest would fall somewhere in between. Depending on how dominant pH1N1 becomes relative to the seasonal strains will dictate whether we'll see double peaks or an overal extended wave on a state by state basis.

Re: USA - Actual ISDS flu trends

Drop in Region 8 possibly due to Utah's early report of week 4 (updated on Tuesday, Feb 1; usually updated on Wednesday). Utah showed extreme drop in ILI for week 4. http://health.utah.gov/epi/diseases/...20211_wk04.pdf

Additionally, WY and ND have not updated their sites. Does that mean ISDS hasn't received their data yet?

[Missouriwatcher]

Re: USA - Actual ISDS flu trends

Upon further review of UT data, ILI was elevated in week 2 due to only two (out of 11) health districts reporting. In week 3, ILI was probably close to where it should be, because Bear River Health District reported in with "high/intense" activity. In week 4, Bear River Health District did not report, thus lowering ILI. http://health.utah.gov/epi/diseases/...son/index.html

Re: USA - Actual ISDS flu trends

I tend to ignore these things (extreme variation on the last date)
at ISDS.
But I hadn't seen it yet on the weekly ED-visits graphs.

Expect a correction in the next days

ahh, they have restricted access

weren't they acquired by CDC, which is a government organization ?
Why keep these flu-data secret

[gsgs]

Re: USA - Actual ISDS flu trends

the weekly data is still public, but not the daily updates

seems that the peak was either the last week or the next week
week 6 or week 7
H3 is clearly going down, the positives-rate peaked in week 4

[JimO]

Re: USA - Actual ISDS flu trends

With H3 dropping in some places and flu B dropping in others, you're probably right about seasonal flu peaking in Weeks 6 or 7. But, pH1N1 hasn't peaked anywhere yet that I've seen on isolates charts. I don't think that it will peak until Weeks 8 or 9, and possibly later in the west. The height of the peak is still in question and will depend, I think, upon how much of pH1 with S185T is circulating.
