😷Latest excellent weekly report on respiratory virus detections from the Australian State of NSW from @NSWHealth, up to last Saturday (21st).
🤒Look at this for the *trends* not as a perfect capture of every case. health.nsw.gov.au/Infectious/cov…
😷Of course, SARS-CoV-2 is a respiratory virus so I'm including it here.
🤒Its numbers dwarf all other viruses in this report sitting relatively stably, at 10,000 reported per day, with a steady majority being RATs, the rest PCRs. 86 deaths were reported.
😷#Flu lab detections have risen impressively fast. Of those typed, most are Flu A/H3N2 (red) viruses with some A/H1N1 (orange) viruses.
🤒No obvious visible sign of B/Yamagata or B/Victoria lineage viruses or their variants.
😷Among the other respiratory viruses reported, there is a coincident, often steep rise in AdVs, RSVs, MPVs, EVs and RVs.
🤒There must be a huge burden of disease in the community right now.
😷Emergency department presentations that were admitted for influenza-like illnesses support this burden. Early, steep and high rise.
😷Emergency department presentations that were admitted for 'coronaviruses/SARS'-like illnesses also support this burden. Dropped off, but still nearly twice the load of the ILI admissions.
🤒Test positivity % is at 12.8% and slowly declining
😷Those who know me know I think little of Flutracking data.
You can see here, if you had no labs, it would say there's some fever & cough. But it notes a decline in this reporting period. Misleading & unsupported by testing data. At all.
I won't be using it again this season.
Things *you* can do to exert some control:
🟠Ensure you're fully vaccinated - boosted for #COVID19 and vaccinated for #flu
🟠Wear a good mask, properly (yes, cover your nose & use the nose wire to seal it up)
🟠These are airborne viruses-stale indoor air is a big risk

Signs flu was stirring were evident back in October. Yet no planning, warning, mask education or preparation. So frikkin frustrating and tiring and boring and unimaginative and stupid.
I can't speak enough to the importance of imagination in horizon scanning.
Some of the poorly captured lives lost to flu in the coming weeks and months could have been saved.
We can do one thing at a time. Often poorly. Here we are knee deep in a flu season that will be over our heads this year, and the headlines exemplify surprise. Retelling the same old stories. Nothing new. Nothing about how to exert some control over our risks (masks).
A small thread on voting in this weekend's Australian (or earlier, if you haven't already voted) election.
It leverages the clean & clear graphics of the @AusElectoralCom and the less clean 😉humor of @thejuicemedia
Yay preferential voting system!
Yay #democracysausage#auspol
An overview of how to fill in your ballot is covered here: aec.gov.au/media/2022/05-…
And a great explainer of what the hell a "preferential voting system" is, here: #YourVoteCounts

#Flu in Australia to 08MAY2022
😷Quite the 5-year exponential rise in lab-confirmed cases (record rate?).
🤧7,173 notifications in past fortnight; 67Z% of the 10,599 for all of 2022 www1.health.gov.au/internet/main/…
😷Massive rise in #flu detections Australia-wide, especially in most recent reporting week
😷It's a FluA season across Aus, mostly A/H3N2 but still a good chunk of A/H1N1. A teensy bit of FluB in several States and Territories. WiIl FluB expand as we role towards winter?
"Almost 40% of patients that shared a hospital room with someone with occult SARS-CoV-2 infection became infected.
The risk was highest for patients sharing rooms with individuals with very low Ct counts. Others" #ViralLoad#InfectiousDose
"although nosocomial spread of SARS-CoV-2 is relatively rare with standard infection protocols, there is a high risk of transmission for patients in shared hospital rooms if their roommate is acutely infected." academic.oup.com/cid/article/74…
"PCR-positive results in contacts independently increased with higher case viral loads (lower cycle threshold [Ct] values)"
"Overall, 85.4% PCR-positive contacts had an index case with an estimated viral load of ≥10 000 RNA copies/ml (Ct ≤ 24.4)." #ViralLoad#InfectiousDose
Can't yet find any #Flu genotyping data for Aus (reporting only starts during "flu season").
So this is what our local southern hemisphere vaccine is composed of. Hopefully, it includes what's circulating.

Good old @nextstrain (I must be rusty) shows that the most recent FluA/H3N2s (Flu's slipperiest "big bad") - reported from Australia - fall within the A/H3N2 3C.2a1b.2a.2 clade (yellow arrow)
Couple of things to note:
🦠both (egg-grown and cell-grown) A/H3N2 vaccines use strains within the same clade, a little older, but look like a good vaccine "match"
🦠very little A/H1N1 strain, B/Victoria or B/Yamagata lineage activity in Aus atm
