1. I think it's pretty safe to say at this point that the U.S. *probably* won't experience anything approximating a #flu season this year. Though flu is flu, so I may regret that prediction. But there really isn't much flu activity at all.
A thread.
2. How little flu activity is there? Well, last week 32 people in the United States tested positive for #flu. Less than 3 dozen. There've been well fewer than 2,000 confirmed cases across the entire country this winter so far.
3. For some context: 2011-12 was a very low activity #flu season. It came 2 seasons out from the 2009 H1N1 flu pandemic. There wasn't much flu in 2011-12 (red arrow), but there was more flu than there's been this winter. (blue arrow)

1. Fridays in the before times were about #flu updates, during flu season. In #Covid times, Fridays are about me being gobsmacked by how little flu there is. For starters: This map. You may never see another flu map like this in another February — at least in non-pandemic times.
2. The amount of #flu activity in the U.S. remains crazily, blessedly low. (And not just in the U.S.)
There's really no flu season to speak of.
3. In the week ending Feb. 20, a grand total of 28 people in the country tested positive for #flu. In February. Which is often the height of flu season. There've been 1500 positive flu tests in the country this entire winter. A-MAZING.

Didn’t wear a mask ...

Didn’t use Track & Trace app ..

Didn’t take a test ..

Didn’t stay at home ..

Didn’t stop seeing family ..

Didn’t have the vaccine ...

Don’t give a fuck. Won’t be having a vaccine passport or a freedom pass or whatever the fcuk you call it. Ever

Night
My Last pint on the 5th October, at my big mates local. 10 yards from door I tell him I can’t wear a mask or ‘QR’ code.

But Scott won’t let you in .. he says

8 hours later Scott knows Bill Gates is trying to shut down his pub & outlaw alcohol consumption & private ownership🍻
Didn’t wear a mask at all in 2019 ...

...never caught the #Flu then either ..

1. A quick #flu thread, from @cdcgov's weekly FluView report. Still almost no detected flu activity in the country. 14 positive diagnoses the week ending Feb. 13. Fewer than 1400 for the season to date. Last year at this time, there were nearly 175,000.
2. I find this graph a miracle, every week CDC posts it. Only 1 child in the US has died from #flu this season. Even in 2011-2012, which was pretty much a non-season season, 37 children died from flu.
3. Here's a look at this year's season, compared to a number of others. The blue arrow points to 2011-12, which never crossed the epidemic threshold (dotted line). This year (red arrow) doesn't come close to it.
Hope it continues thru the end of the winter.

1. #Flu thread.
This seems truly to be the year that flu forgot. Almost no flu activity in the country. Last wk 18 people in the US tested positive for flu. Fewer than 1,400 flu diagnoses (by test) so far in 2020-21.
Same week last yr nearly 17,000 people tested positive for flu!
2. Almost no #flu means almost no flu deaths among kids. This year so far only one child has died from influenza. At this time last year, 92 children had died and 195 died over the course of the entire 2019-20 flu season.
3. Almost no #flu is not the same as no flu. In the past week, the total number of people hospitalized for flu this season rose by 10 from last week. Not clear all those would have been hospitalized in the one week; could be data lags, I suspect. Still, a very low number.

#PICANet annual report 2017-19 was released today.
Key takeaway messages from the annual report are available in the report summary.

1. UK/RoI #PedsICU have around 20k admissions/year and ~140k bed-days/year
2. 96.5% of all admissions survived
1/n
3. Deaths in #PedsICU accounted for ~1/6 of all child deaths
4. all UK/RoI PICUs were contained within the "funnel" of the risk-adjusted SMR funnel-plot (i.e., no outliers)
5. Unplanned extubation rates were around 0.5/100 vent days
6. 48h unplanned readmission rates ~1.7%
2/n
7. Of the >4000 #PedsICU transfers, >75% were mobilised <60min of the referral.
8. Occupancy rates remained high
9. Nurse-establishment vacancies meant that only 25% of PICUs met recommended standards of whole-time equivalent nurses.
3/n

1. Seeing as it's a Friday in what typically would be #flu season, here's a flu update, from week 4 data (ending Jan. 28) from @CDCgov.
There continues to be almost ZERO flu activity in the country. So much for the "twindemic" (knocking wood right now) people were warning about.
2. Last week there were only 25 positive #flu tests reported in the entire country. So far this year there have been 1300 — out of >half a million tests administered.
#Covid19 activity could be masking some flu, but people are getting tested. They aren't testing positive.
3. To put those last numbers in context, this time last year there were 12,700 positive cases in the week and more than 100K positive cases to that point in the flu season.

1. #Flu activity remains amazingly low this winter. 🙏🏼
For the week ending Jan 23, less than 1% of specimens tested for flu came back positive.
In the same week last year, 25.6% of flu tests were positive & there had been +93K positive tests to date. This year: 1276.
Thread.
2. Some news this week: A young child who lives on a farm where pigs are raised contracted swine #influenza. It was a vH3N2 — the "v" in the name means variant, which in flu terminology means a version of #flu that normally circulates in an animal species. The child is fine.
3. Speaking of children, the #flu death toll among kids in 2020-21 stands at 1. In regular flu seasons, somewhere between 100 and 200 children typically will die of flu. Not this year, it seems. 🙏🏼

Exclusive:

The number of people getting flu has plunged by 95% to levels not seen in more than 130 years

@lusignan_s, director of @rcgp flu surveillance centre and professor of @oxprimarycare @uniofoxford, says flu has been ‘almost completely wiped out’

thetimes.co.uk/article/hygien…
The second week of January is usually the peak of the #flu season, with thousands in hospital

The five-year average rate of cases reported to GPs in England is 27 per 100,000 people, per @rcgp flu surveillance centre

This year it was just 1.1 per 100,000 thetimes.co.uk/article/hygien…
In the second week of January, UK health analysts did a double take when they saw the #flu positivity rate — a standard metric of community flu activity — was 0.0%

Not one of 1,894 samples tested positive

1. Count your blessings time.
It's Friday, @CDCgov's FluView has been published & wow. Wow. Wow. Wow.
There continues to be almost no #flu activity in the U.S. Given that there's plenty of #Covid19 activity, you cannot explain this simply by masks + social distancing.
2. Lots of people are being diagnosed with #Covid19 — 186,000 on Jan. 21 — so clearly people are contracting respiratory pathogens. Just not #flu so much.
23 positive flu cases in the US in week 2 (ending Jan 16) - less than 2 dozen - is crazy low.
3. Also crazy low: So far this year the hospitals in the national flu surveillance network have reported 136 people hospitalized with serious #flu infections. Last year by week 2 of the flu season, 5,786 people had been hospitalized for flu.

1. In normal (ie non-Covid years) Fridays are #flu data update times. @CDCgov puts out #influenza data on Fridays. Flu has been overshadowed by #Covid19, but it still bears watching.
So, a thread.
2. #Flu activity remains low. It hasn't disappeared entirely but so far we haven't seen enough flu to talk about a "flu season," as you can see from this graph. Red arrow points to this year so far. Crossing the black dotted line=flu season. Not clear if we'll have one this year.
3. Very few of the respiratory infections tested for #Flu so far this year have turned out to be positive. These numbers are extraordinary. That said, there appears to have been a tiny upward creep. What that means remains unclear.

1/ There were countless theories put forward in 2020 on how we should deal with the #COVID19 pandemic. The most unscientific of them all was #Covidzero. To appreciate why, we must understand the concept of #endemic viruses; thread

#Coronavirus #lockdown #Canada #Ontario #cdnpoli
2/ According to the CDC, a disease is endemic when it is constantly or predictably prevalent within a population or region. Both #influenza & coronaviruses are #endemic; meaning that they constantly circulate within our population

#COVID19 #Coronavirus #lockdown #Canada #Ontario
3/ Let’s look at the H1N1 influenza pandemic to illustrate how a resp. virus becomes endemic. #H1N1 entered the human population in 2008-2009. The following data is taken from the #US CDC’s Fluview Interactive tool

.@DrNancyM_CDC on #COVID19 vaccinations: It's the early stages of the complicated task but a task we're up for.
These are new vaccines & new platforms.
Storage/handling/administering slightly complicated.

#STATPlusConversations .@DrNancyM_CDC: Now that facilities/hospitals have experience with #COVID19 #vaccines & holidays over, expect pace of administration to go up massively in next couple of weeks.

1. A #Flu thread:
Because Friday was a holiday, @CDCgov published FluView today.
US #flu activity remains super low, thankfully.
So far this season a single child has died from flu. It's early & peds deaths generally come later in the season, but there are often more by now. Image
2. So far in the 2020-21 #flu season, the US has recorded 877 positive flu tests, out of more than 360,000 conducted. That is amazingly low. Image
3. This FluView graph gives you a sense of this #flu season versus multiple recent flu seasons. Pretty much nothing compares. The closest season was 2015-16, the orange line in the graph, which was crazy late and very mild. You'll want to refer to this when you read tweet 4. Image

1. FluView, @CDCgov's weekly #flu report, went up today. It was for the week ending Dec. 19. Remarkably little flu to be found in the U.S.
People are being tested for it — more than 300K tests to date this season. But so far, only 720 positive tests.
Thread.
2. Things could change, #flu wise. But so far, this is looking like a non-season. Note the orange line, though -- the 2015-2016 season started remarkably late, only going above the epidemic threshold (dotted line) in late January-early February.
3. So far this #flu season there has only been a single child who has died from flu. A blessing.

HIGH RISK #COVID PATIENTS:
Over age 50, with 1 or more other medical conditions:
Obesity
Diabetes
Lung diseases (COPD, asthma, etc)
Kidney disease
Hypertension
Autoimmune disorders
History of cancer treatment
History of regular corticosteroid use
aapsonline.org/covidpatientgu…
The vast majority of deaths from #COVID occur in those 75 years old and older, with most of those already sick with other illnesses. A large percentage are in nursing care facilities, over 80 years old, and with an average of 2.5 other medical conditions
aapsonline.org/covidpatientgu…
The chances of someone <50 years old with symptoms dying from COVID-19 is 0.05%. The chances of someone under 18 years old dying from COVID is near 0%. Those who do are those with severe underlying medical conditions. Roughly 7 times more children die from #flu than #COVID19.

Shocking!
Influenza positive tests reported nationally.
1st column reported by public health labs, 2nd column clinical labs

Rows are 2020, 2019 & 2018
Data avail for 2020 thru Dec 5 so I made dates for 2019 & 2018 match.

Wealth of data here, do verify. cdc.gov/flu/weekly/ Image
#influenza #data #flu
In case anyone can't see the numbers, here they are... (I added all the diff types together for each year)

Influenza reported by Public Labs:
2018- 45,881
2019- 46,974
2020- 106

Influenza reported by clinical labs:
2018- 183,483
2019- 250,494
2020- 496
Here's another doozy regarding case counts...
The most likely people to test positive for covid are...
Healthcare workers who are tested at least weekly, &
people who have covid & are checking often to see if they still have it...
If each test is reported as a case? Image

THREAD: Tamiflu for #influenza prevention – the evidence

1/6 In 2019 21,000 BC citizens were prescribed Tamiflu (oseltamivir), many to prevent the flu. Flu prevention guidelines. AMMI Canada ammi.ca/?ID=171

Systematic review of Tamiflu safety: pubmed.ncbi.nlm.nih.gov/27246259/
2/6 Tamiflu for prevention ↘️ symptomatic flu (by 3%, NNT=33) with uncertain effect on asymptomatic flu.

One likely explanation is that Tamiflu has a central symptom lowering effect but may not ↘️ viral transmission.
pubmed.ncbi.nlm.nih.gov/27246259

#influenza #flu #tamiflu
3/6 Tamiflu doesn't reduce risk of developing flu-like illness though it can make people feel better (i.e. fewer self-reported symptoms) & reduces fever.

There is not enough evidence to say it prevents death, hospitalizations, or flu complications

1. A thread on some possible knock-on benefits of masking/distancing for #Covid19.
Before the pandemic, 2020 was expected to be a big year for #AFM, a kind of mysterious polio-like condition that @CDCgov has been tracking in kids since 2014. Cases spike every second autumn.
2. It's not 100% clear but it's thought infection with an enterovirus causes an aberrant immune response in some kids & they go on to develop acute flaccid myelitis. 2020 was expected to be a surge year for #AFM. Hasn't happened. cdc.gov/acute-flaccid-…
3. It's still too early to be sure, but #flu activity may be lower this year too, because of mask wearing, hand washing, distancing & less international travel. As one ID doc told me this week, hospitals need this kind of a break; they cannot cope with flu on top of #Covid19.

News on #vaccines against #COVID19 is very encouraging. Its timely to remember the fantastic impact that other vaccines have had over the last 200 yrs in Ireland - apart from clean water, vaccines have saved more lives than any other public health intervention @HSEImm @RCPI_news
In 1863 vaccination against smallpox was made compulsory for all children born in Ireland. Deaths fell from 7,550 for the decade to 1880 to the last reported death here in 1907. Smallpox was declared eradicated in 1979 – this one vaccine saved 100s of millions of lives globally. Image
Diphtheria was a very common cause of death among children until the 1940s - there were 318 deaths reported in 1938. With the introduction of a vaccine, the number of deaths fell year on year with 5 deaths in 1950; the last death notified from diphtheria was in 1967. @HSELive Image

Thread of public education messaging which can help us get #COVIDー19 under control.

Misconception #1: how #COVIDー19 is spread.

-covid is like glitter. When someone coughs or sneezes, talks loudly, sings, glitter is released into the air and lingers in the shared air.
Misconception #2: come back if “worse or short of breath”

-Most people can’t quantify short of breath, esp if they’ve never felt short of breath before

-Walk in place for 1 min.Sing your ABCs. If you can’t finish song or steps w/o breathing hard, you need to be seen immediately
Misconception #3: only old or unhealthy people die from #COVIDー19

-Everyone is at risk for #COVIDー19. I have cared for healthy 20,30&40 year olds who have died from covid or are now discharged home on oxygen because their lungs are destroyed.

-PS. Every age is a spreader.

1. Short #flu thread:
@CDCgov didn't post its weekly flu update, FluView on Friday because of the holiday. It's up today.
Flu activity in the US remains lower than normal at this time of year. This time last year, what would turn out to be a very active/long season was underway.
2. Most jurisdictions are reporting little #flu to this stage. Don't know how much to read into that. Sometimes flu activity starts picking up this early but sometimes it's later. The orange line in the graph in the tweet above is from the 2015-16 season, which was very late.
3. As this graph shows, there's been a lot of death from pneumonia, #influenza & #Covid19 in 2020, but it's been Covid-related since the spring. #Flu deaths seem to have stopped by late April or early May. FluView report is here: cdc.gov/flu/weekly/ind…

1/ Q: How do COVID-19 & the flu compare?

A: They are VERY different. In short – COVID-19 is more deadly, more people are susceptible to it, we have fewer treatments, and even “mild” bouts can leave long-term symptoms. Photo from jmexclusives at Pixabay.com
2/ To address the elephant in the room: **COVID-19 is MUCH deadlier than the flu.** In fact, since December 2019, #COVID19 has killed more people in the U.S. than influenza has in the past 5 years combined. mck.co/3qh350b
3/ Of course, the burden of COVID-19 is in ADDITION to all the other causes of death around the world, including continuing deaths caused by the flu. bit.ly/2VcB2k2
