#Flu in #Queensland, week to 28AUG2022
😷Total numbers are low but a little tail is wagging
😷Hospital admission numbers because of #flu, broken up by region of Qld, with historical context.
🤒Few but lingering at that level
😷Ian's take-home messages...
📢Flu seasons pass-a good (N95) mask, worn properly, indoors increases your chances of missing this one and of protecting others from you
📢Stay home if sick (=new: cough, sneezing, headache, fever, fatigue)
📢Stay away from the elderly if sick
😷These graphs & tables were screen-captured from the latest #Queensland Government #Flu surveillance report found here. Great work.
health.qld.gov.au/clinical-pract…
Private lab, Sullivan Nicolaides Pathology show rates of adenovirus (ADEN) and human metapneumovirus (HMPV) positivity rising ⬆ in Queensland.
Rhinoviruses remain detectable in a fifth of samples (RHINO)same↔
Respiratory syncytial virus (RSV), Flu, SARS-CoV-2 declining⬇
Those two graphs from: snp.com.au/clinicians/res…
And in New South Wales, HMPV now slowly declining, ADEN may have peaked, RHINO may be steady and enteroviruses ticking along.
I wish we had a parechovirus chart here.

"The mutations [SARS-CoV-2] just keep on coming"
They do. And they will. Unless the world undertakes the kind of global program used to eradicate polio.
And let's be real. We're just not going to be doing that. Nope.
So what does that mean?
It means the virus will keep evolving in whatever direction results in a successfully transmissible new variant. You may have heard all this two years ago. RNA viruses like this one continually evolve. Nothing has changed since then except much more immunity to try to escape.
You may even have heard about it before this pandemic. Because its what flu always does as well. It's why we need new flu vaccines each year. Because the flu viruses usually "move on" in the intervening time.

Optimizing and Unifying Infection Control Precautions for Respiratory Viral Infections
-I love this piece to absolute bits. academic.oup.com/jid/article/22…
"is high time to modify infection control guidelines for respiratory viruses to recognize that that their transmission is more alike than different and that most transmission is attributable to aerosol inhalation"
On surgical vs N95 mask studies...
"In retrospect, however, we now recognize that the majority of healthcare worker infections are acquired in the community and the majority of SARS-CoV-2 and influenza infections are transmitted by asymptomatic and presymptomatic individuals"

‘Not some weird elitist class’: the scientists bringing an urgent message to the streets of Hobart
-makes some really good points.
theguardian.com/science/2022/a…
I like this one especially...
“It really bothers me how exclusionary science can be. You’ll have a university that brings, every week, some interesting researcher to give a talk to some departmental seminar for 30 people. And the public is not invited."
“Instead, you’re just talking to the same people over and over and over.”
The obvious argument is that this would be too dense for the average person. And for many that's true. But put them on Zoom anyway.

😷Australian National #Flu data up to 31JUL22.
🦠lab-confirmed total cases⬇ (peaked in ~first week of June)
Graphs from: www1.health.gov.au/internet/main/…
😷Yes, there is undoubtedly more testing capacity in Aus after labs beefed up PCR testing for the pandemic.
😷To check if this is a real change in #flu cases, we can look at positivity rate, deaths, hospital beds & ICU occupied beds with flu-positive patients
🛏️year to date (YTD from April 2022), 246 lab-confirmed influenza deaths (+65 since last fortnight)🛏️YTD, 1,581 sentinel hospital admissions (+92,⬆️)
🥽YTD, 103 (6.5%) admitted to ICU (+100,⬆️)

A 𝙢𝙖𝙨𝙨𝙞𝙫𝙚𝙡𝙮 important thing still missing from conversations we're not having: excess death in winter-now & pre-pandemic.
•Respiratory viruses play a role in such seasonal death & harm
•In big flu years-like 2017 & 2019-we saw excess deaths
In low #flu years like 2018 & in 2020-21 (when we briefly cared about protecting each other & our older populations from a pandemic pathogen), we saw a real drop in deaths in accordance with the huge effort we put in to prevent virus transmission & protect our healthcare system.
Before projecting & overlay your own views & fears onto my words-I'm 𝘯𝘰𝘵 advocating for lockdowns, border closures or mask mandates. I seek communication, education & engagement around masks, & the implementation of clean𝘦𝘳 indoor air standards/tools to reduce aerosols

I'm not going to this year's Qld #Ekka but I am going to make scones.
And hot dogs.
And have strawberries & cream ice cream for desert tonight. And eat small chocolates.
They came out okay.
Jam then whipped cream (with vanilla and honey)
(not sorry @ketaminh)
