(1/3) One of the biggest challenges of having multiple respiratory viruses circulating at the same time is the large and sudden surge of illnesses that can overwhelm the health system. It also means there is a lot of virus circulating in the community.…
(2/3) This means we may be more likely to encounter viruses as we interact with others in schools, workplaces and social settings, especially indoors and if masks are not being worn.
(3/3) This is why #VaccinesPlus is so important right now. Although no individual layer of protection is perfect, when used consistently & together, layers provide very good protection against #COVID19 & other respiratory infections. #Flu #RSV

Dear ON,

Stop waiting for those who are behaving the way they are with #IStandWithCUPE 😷 to tell you to put #Masks back on to prevent airborne spread of airborne viruses.

A non-exhaustive🧵 of their behaviour so far:…

“increasing evidence that SARS-CoV-2 can cause immune dysregulation… a potential increase in acquired impaired immunity in the ON pop could have significant impact on the incidence & assoc burden of infectious diseases“…

For the avoidance of doubt:
SARS-CoV2 transmission is mainly aerosol, some droplet - proportion varies with activity. Hence, indoors = super-spreader events, outdoors = dissipates quickly.
Well ventilated/filtered indoor spaces or outdoors, keep distance to avoid droplets, reduce
time spent in proximity to others, wear well-fitted filter masks (FFP2/3) if distancing is problematic, for long durations, and/or if prevalence is high.
Poorly ventilated/filtered indoors - masks as above are ESSENTIAL. Limit time, distance if possible to avoid direct exposure.
Now apply some logic...
Face shields do next to nothing, unless you're expecting a sneeze in the face, and even then will only prevent "direct inoculation"...

COVID is killing thousands of Australians who would have otherwise lived, likely to be 20-30,000 by year's end. This fig shows that, after saving lives in 2020 (another story), once this line crossed the zero in late 2021, we were in ‘excess’ territory. 1/

I can’t shake the feeling that we continue to be cheated out of getting through this pandemic safely

A short 🧵 on some of the reasons #CovidIsntOver
💨 #CovidisAirborne yet we don’t monitor or purify our air #BreathBackwash

😷 Education around high quality fitted masks continues to be minimal. Respirators remain inaccessible for many. As a consequence, ineffective (cloth, surgical) masks are being used #MindTheGap
🧪 We use rapid antigen tests with no #PaidSickDays and many can’t isolate for the full duration of contagiousness

💉 Vaccines were made to be a panacea when we needed to layer it with all of the above. This disappointment has stopped people from being uptodate with their C19 💉

1/3 Fall #COVID19 Ready? NACI recommends that all older adults (≥65 yrs), as well as people aged 12-64 yrs at ↑ risk of severe illness from COVID-19, should be offered a fall #COVID19Vaccine #booster regardless of the # of previous booster doses.…
2/3 Don’t delay! If the bivalent Omicron-containing mRNA #COVID19Vaccine is not readily available, Canada’s NACI recommends that an original mRNA COVID-19 vaccine should be offered to ensure timely protection. #VaccinesPlus
3/3 Individuals choosing to delay a #COVID19Vaccine booster dose in anticipation of a new vaccine should carefully consider their individual risk. Layering individual public health measures can help protect you & others from #COVID19.… Image

So, yet again the UK is an outlier for kids vax.
Kids turning 5 after Aug22 are now unable to access SARS2 vax.
This is short-sighted, will cause profound harm in the short term, and could be detrimental to "living with" COVID in the longer term. Short 🧵…
The UK has an established narrative that infection in children, esp Omicron, is harmless. Whilst IFR in recent ADULT vaccinees is lower, we've long known that omicron ≈ delta 4 <18s. So MASSIVE prevalence = huge impact. Excellent summary from @dgurdasani1
There are many that quote the incidence of severe disease in kids relative to adult disease, this is the wrong comparison. Other vax preventable infections in kids cause ⬇️⬇️harm. Also, ratios are fine 4 personal risk, but you MUST assess ABSOLUTES across populations.

So they examined all the placentas of people known to have COVID-19 exposure during pregnancy and placentitis was found in people not fully vaccinated against COVID-19.

Study period pre-vaccination and early delta approx.
Mild maternal disease was associated with severe outcomes. 15/21 patients with stillbirth and COVID-19 placentitis had mild or asymptomatic disease initial COVID-19 infection.
January 1, 2020, through November 4, 2021 was the study period, and CDC published guidance that vaccines were recommended and safe on 11th August 2021.

That means that any women that were vaccinated and protected from placentitis would have been recently vaccinated.

This is a very carefully considered, thought through thread, and yet I am expecting the opposite.
First assumption.

Long COVID is a single entity.

It probably isn’t.

If it was, you could expect the whole thing to behave in a certain way, and respond to prevention similarly.

It probably won’t.
There will be some factors that are reversible. Those will respond well to prevention, such as timely, effective boosters.

I think I know how the pandemic will end… and it’s not pretty.
A while ago I read a paper about how outbreaks end in animal populations.

It involved the population density becoming so low, that disease could no longer transmit efficiently.
In humans, this is likely going to mean that we will reduce our population numbers somewhat also, but we will not get to very small number, or extinction, because the remaining will do what is required to survive.

As we all anticipate a GNB press conference today...
...I had a look at how many YouTube views the old COVID briefings were getting.
Remember those?
The last one was Feb 24, when BA.1 was dominant. They made us go through the whole BA.2 wave without any live guidance.
/1 GNB's COVID briefings used to get 25-29k views. NB hasn't ha
Now the BA.5 wave is here, and we have hundreds of thousands of NBers whose most recent vaccine dose was over 6 months ago (which means their antibodies have waned significantly - protection from infection has waned). Still no briefings.
Anyway, there's a bunch of volunteers out here trying desperately to inform the public about all kinds of aspects of SARS-CoV-2 that are really important to know, because they help you make better informed decisions. It is slow going.

1/5 Today, the COVID-19 Immunity Task Force (CITF) announced seroprevalence results from 21 studies funded by the Government of Canada, estimating the level of infection during the Omicron wave up to the end of May 2022.…
2/5 Antibodies to certain blood proteins known as “nucleocapsids” only develop in those who’ve been infected. So detecting their presence in blood (seroprevalence) is a way to estimate the proportion of people with past #SARSCoV2 infection.
3/5 CITF results confirm the massive scale of the #Omicron wave. Before Omicron arrived in Dec 2021, ~7% of Canadians had infection-acquired antibodies to #SARSCoV2. Then from Dec 2021 to May 2022, that proportion rose to 45%!

Lucky we have an ongoing and responsive vaccination strategy for people of all ages then isn’t it?

Maybe we should try something new?

It wasn’t all that unexpected. Parts of the new sub variants are delta, or delta-like.

So if delta didn’t protect well from omicron, I wouldn’t have thought omicron would protect well against child of delta.

1/4 #COVID19 key concerns 🇨🇦 : not unexpectedly, ⬆️ in-person activities following easing of public health measures, together with spread of the more transmissible BA.2 variant and some waning of immunity, may be contributing to ⬆️ transmission.…
2/4 Average daily cases have increased by 28% vs. last week, indicating resurgence is underway nationally (Mar 25-31, 2022); also 7-day lab test positivity (Mar 23-29) ⬆️ to 16% and wastewater signals are ⬆️ in many localities.
3/4 Although overall high vaccination rates are expected to lessen the impact on hospitals, severe illness trends have begun to increase in many jurisdictions (range 3%-27% weekly ⬆️ in daily number of patients with #COVID19 in hospitals).

I did an interview the other day in which I was asked when WA’s omicron wave will peak. Naturally, it’s something most people want to know, but in retrospect I think it’s the wrong question. Instead, we should ask how we can minimise the impact of the current and future waves.
The omicron wave won’t be the last. Why would it be? Look at the UK: the first wave of the original strain was followed by the alpha variant, then the delta variant, omicron BA.1, and now omicron BA.2. An average of ~100 people continue to die per day.
We can expect more waves in future, driven by waning immunity and/or the emergence of new variants.

If we allow high levels of transmission, we create the conditions for new variants to emerge. It’s a never-ending cycle, which harms lives and livelihoods.

🧵A thread - Same birthday gift three years in a row: a lesson in public health and politics
1/ It was the evening of Thursday, March 12, 2020. I was out shopping with my daughters. My youngest daughter had a gift certificate tucked in her purse. She was eager to find something to spend it on.
2/ Having turned nine years old, the day before, she was still bouncing with happy birthday joy.
Walking through the aisles of toys, I heard a notification on my phone. A text from a friend relayed the news that schools would remain closed after the upcoming March break.

Brilliant analysis on the death toll for the pandemic's first 2 years. As thought, excess deaths ~3x more than confirmed COVID deaths at 18.2 million people. Greater than the effect of the BIG 3 (HIV, TB and malaria combined). Still ongoing of course. 1/…
Tragic as it is for the world, from a parochial Oz point of view this highlights an extraordinary success over this period. For example, had we had the same rate as the US (~1.2m people died there), Australia would have had ~100,000 additional deaths 2/
Furthermore, Oz was able to vaccinate much of its population BEFORE they encountered the virus - as many eventually did during the omicron wave beginning in dec 2021. The formal policy of no community transmission delivered these extraordinary outcomes; credit to all Govts. 3/

Today, Western Australia ended the border controls that have kept its people safe for two years. During that time, only 10 people died from COVID-19, making the state’s response one of the world’s best.
Unfortunately, the emergence of the omicron variant finally made Western Australia’s elimination strategy unviable.

Nonetheless, the Government continues to follow a suppression strategy for now. Better vaccines may make this easier in future.
I’m not concerned by the border reopening, because it will now make little difference to the trajectory of the omicron epidemic in Western Australia.

The most important thing was that we bought precious time to get third dose levels up.

1/5 #COVID19 key concerns 🇨🇦: while we’ve passed peak #omicron, measures are still needed to relieve the pressure on our hospitals. In particular, closing vaccine coverage gaps and maintaining core personal protective practices.…
2/5 In particular, millions of eligible Canadians could reduce their risk of ending up in hospital with severe COVID-19 disease by getting up-to-date with #COVID19Vaccines/mRNA #Booster as eligible/ recommended.
3/5 Evidence shows two doses of #COVID19Vaccines offer reasonably good protection against severe disease, and getting an mRNA booster dose as eligible offers superior protection, keeping more people out of hospital and preventing more deaths.
