Is anyone else still been covid free? I know someone else who was covid free until last month when they caught it bad.

I haven't had any trace of it but I don't go out much. Mainly just weekly shopping at the supermarket.

Canuckabroad:

This was asked on Reddit and a number of people did respond (although it's also possible they could have been asymptomatic). Unless people have largely been living like hermits, pretty much everyone will have been exposed by this point.

I think if you WFH and avoid people when they have it, it is possible. I have been going into shops unmasked etc, but I haven't been hanging around children, and schools and workplaces seem to be where it largely spreads between households.

Everyone I know who "never had it" have caught it in the past 6 months.

I've never had a second bout (but I WFH and dont go out much either). I did real sick when I got back from LA last October (the guy next to me was coughing and sneezing) but I never tested positive.

My son who just joined NZDF had to have a mandatory (3rd?) booster before joining. Guess what happened when they turned up at basic training in Feb? Almost everyone in the intake got it.

My wife and I have not had covid yet, which by all accounts is a miracle considering she works in a medical practice

Just because you have never felt it doesn't mean you haven't had it....

Part of the problem is that there has never been any population serological sampling to determine the actual population infection rate..

"Many people (estimates vary from 20-60%) infected with SARS-CoV-2 will remain asymptomatic."

I don't think I've had Covid-19.

If I have had it, it's been asymptomatic. I understand that's a possibility, but I have taken multiple RATs as I visit Rest Homes regularly. My judgement is that I have (so far 😰) avoided it.

I have had every vaccine dose & booster offered to me - I've had six doses so far - pretty much as soon as they became available. I obeyed the rules during the lock-downs and continued mask wearing for several months after it became optional

Pretty sure wife, daughter, and I haven't had it. Wife and I have had all the injections we can.

Daughter is a hospital physiotherapist, so has had quite a few tests, all negative.

Fingers crossed.

From the "no shit sherlock" institute: https://www.rnz.co.nz/news/national/512698/long-covid-teachers-healthcare-workers-most-vulnerable-report-finds

Actual report is at https://www.phcc.org.nz/briefing/long-covid-aotearoa-nz-risk-assessment-and-preventive-action-urgently-needed

Sadly for everyone I'm betting this government won't do anything at all.

That group of people are stuck in the zero covid era and they're highly unrealistic. I follow Amanda on social media and she seems to present studies leaning to her view. Ignores the studies across the ditch it seems. I think the Queensland chief health officer was calling for the term long covid to be dropped. There was a study comparing flu vs covid outcomes and the rates of ongoing symptoms were similar.

As someone else posted, it's just been the sheer numbers of people that got infected with covid meant long covid seemed to be more prevalent, but the flu vs covid study showed it's very similar to other post viral syndromes.

The call to expand vaccine eligibility to younger groups isn't going to happen. There is still the issue of myocarditis which isn't worth getting vaccinated for. Kids are less likely to get long covid. It seems severity of covid ie ending up in hospital is strongly linked to getting long covid which isn't a surprise really. The study Amanda posted on social media recently didn't address that. There was an Aussie study or something that did address that link. If you've stayed out of hospital the risk of long covid is remarkably low. I think it was around 0.09%? And was 2% if you'd been hospitalised in a vaccinated population in the Omicron era. I'd rather we spend health money on medicines that actually work for people instead of having kiwis move across the ditch because medication is funded there. I agree that vaccination reduces long covid but when you get covid that's kind of a booster in itself. There are some studies looking into long covid treatments so will see what comes of those.

The call for hepa filters in schools etc isn't going to happen either. Too costly for very little benefit if any. I mean kids get really close so a hepa filter a few metres away isn't going to change anything when they're sitting so close together for long periods. Victoria trialled this. I'm not aware of it changing any outcomes. Besides there are so many other places kids can get infected too. Would be a huge investment and who is going to pay for that when there's a lack of evidence it even works in the real world? Best to spend money where it's beneficial.

These are the flu vs long covid links.

If you're subscribed to medium, Gideon MK (Aussie epidemiologist) wrote an article on future risk of long covid. He's very well balanced in his views and explains things nicely. He's also on social media X. He wrote another article about the peak of long covid has passed.

Anyway I find it interesting to watch both sides of the argument. In general I find our public health voices with Amanda, Michael Baker on this topic to be pretty out of touch with reality. I'm aware there's a group called Aotearoa covid action vouching for interventions. I do wonder if these people will be saying the same thing in a few years or if they will tire of it.

the other problem was how they where doing it.

many here started using "air cleaners" which simply sucked/blew all the virus laden air into the pupils instead of away from them. so it would cause infections, especially to those near the filters. also a lot of the ventilation was done back to front causing the same issue.

people don't understand ventilation and airflows, the buildings are often not designed for it.

YMMV

Having good ventilation evidenced by low Co2 levels, and even adding filtration would seem to potentially have a number of benefits.

Teachers I knew of before covid did confirm the general view that they were first in line for respiratory illness, flu, colds.

In general having low Co2 levels and low particulates of any sort is a good thing.
Your school is lucky enough to be next to a busy motorway or industrial plant.

This was a pre covid study from Taiwan

Effect of ventilation improvement during a tuberculosis outbreak in underventilated university buildings
https://pubmed.ncbi.nlm.nih.gov/31883403/

""
Here, we measured the effect of improving ventilation rate on a TB outbreak involving 27 TB cases and 1665 contacts in underventilated university buildings. Ventilation engineering decreased the maximum CO2 levels from 3204 ± 50 ppm to 591-603 ppm. Thereafter, the secondary attack rate of new contacts in university dropped to zero (mean follow-up duration: 5.9 years).
""

Example of another study in SARS-Cov2 times measuring aerosols.

SARS-CoV-2 transmission with and without mask wearing or air cleaners in schools in Switzerland: A modeling study of epidemiological, environmental, and molecular data
https://pubmed.ncbi.nlm.nih.gov/37200241/

""
Daily average aerosol number concentrations without interventions were 177 ± 109 1/cm3 and decreased by 69% (95% CrI 42% to 86%) with mask mandates and 39% (95% CrI 4% to 69%) with air cleaners. Compared to no intervention, the transmission risk was lower with mask mandates (adjusted odds ratio 0.19, 95% CrI 0.09 to 0.38) and comparable with air cleaners (1.00, 95% CrI 0.15 to 6.51).
""

Its not elimination, but reduction helps in the lottery of life, and over anything that can spread via aerosols.

had a quick look at the taiwan one. it had zero ventilation and not surprisingly very bad co2 levels. in which case ANY ventilation would have made an improvement. the whole hvac design looks like crap (eg entire floor is done by one inlet and outlet).

with any virus thats breathed out with warm breath tends to go up. if you use high mounted exhausts and low mounted inlets, that helps pull it up away from people. if you do it the other way around here (which is what they tried to do here) you push down the virus laden air into the people. its even worse if the inlet and outlets are both low mounted so the airflow goes through the crowd of people (which is what most portable air cleaners do). the old style buildings we often have here, with high ceilings, open windows at the top and opening the door actually works well as natural ventilation is up taking virus/co2 away from people.

in my opinion, this person is a deplorable conspiracy theorist, scammer, sovereign citizen nut. And the judge changed his sentence. Incredible.

Ridiculous. I hope this is a wake up call to potential/future scam victims of this low-life, now they know who he is.

Had my 7th Covid vaccine on Saturday. I really must be one of the "Walking Dead".

Absolutely easy to get it and the Flu Vaccine without an appointment at the Wigram Unichem. (Christchurch)

Very good vaccinator too, probably the best I've ever had!
