apparently someone tested ice cream and ice cream tests positive

Even if New Zealand had COVID in the wild, current thinking is it's impossible to get Covid from milk powder, or even a public toilet seat.

Fomites is anything which can carry infection, such as clothes, utensils, and furniture. Also known as contaminated surfaces, such as a toilet seat.

English translation for below: if you've got a surface covered in COVID, there's a person nearby who has COVID. So look for a person person not wearing a mask, and remind them they're are killing people.

WHO: Fomite transmission

...Respiratory secretions or droplets expelled by infected individuals can contaminate surfaces and objects, creating fomites (contaminated surfaces). Viable SARS-CoV-2 virus and/or RNA detected by RT-PCR can be found on those surfaces for periods ranging from hours to days, depending on the ambient environment (including temperature and humidity) and the type of surface, in particular at high concentration in health care facilities where COVID-19 patients were being treated. Therefore, transmission may also occur indirectly through touching surfaces in the immediate environment or objects contaminated with virus from an infected person (e.g. stethoscope or thermometer), followed by touching the mouth, nose, or eyes.

Despite consistent evidence as to SARS-CoV-2 contamination of surfaces and the survival of the virus on certain surfaces, there are no specific reports which have directly demonstrated fomite transmission. People who come into contact with potentially infectious surfaces often also have close contact with the infectious person, making the distinction between respiratory droplet and fomite transmission difficult to discern. However, fomite transmission is considered a likely mode of transmission for SARS-CoV-2, given consistent findings about environmental contamination in the vicinity of infected cases and the fact that other coronaviruses and respiratory viruses can transmit this way.

And more importantly not a single piece of evidence to suggest that Covid could be contracted by ingesting food that was contaminated.

“There is a possibility that these common adverse reactions, that are not dangerous in fitter, younger patients and are not unusual with vaccines, may aggravate underlying disease in the elderly,” Madsen said. “We are not alarmed or worried about this, because these are very rare occurrences and they occurred in very frail patients with very serious disease,” he emphasised. “We are now asking for doctors to continue with the vaccination, but to carry out extra evaluation of very sick people whose underlying condition might be aggravated by it.”

freitasm:

Boris wants negative tests and "self-isolation" for ten days. We know "self-isolation" doesn't work, so there is this next (story not online yet, out Sunday UK time):

When NZ went into lockdown, we were still allowing people to self isolate at home, as that I recall our lockdown occurred prior to us starting to use MIQs. I recall many people seemed to think that requiring all returning NZers to go through MIQ was not practical to do. Under those conditions we did get rid of the virus, but we were lucky as it hadn't spread that far in NZ, and it wasn't a prevalent overseas at that time. But this was mainly because NZ was in lockdown, so it was more effective, as everyone was supposed to be at home anyway, so people were socially isolated from those returning anyway. The main difference was that people who were isolating after returning to NZ weren't also allowed to go out to supermarkets or essential work etc, even though some obviously did still go out prior to lockdown, as that is how it spread. UK is in lockdown, but maybe not as strict as NZs one. 10 days isolation, when 14 days is seen as the minimum IMO doesn't make any sense.
UK is already heavily infested, so they have no chance of elimination until enough people are vaccinated, and although they are expected to be in lockdown for a long time due to the mass death now occurring, they are more about flattening the curve and keeping their economy running so their health system didn't reach peak capacity, which they failed to do. NZs approach looks to have worked far better, but we were lucky and also lucky to be on an isolated island where borders are easily controlled.

@Scott3: Re the aussie vaccine situation, the big news story there today is that the cira 72% effecancy of the oxford vaccine (that aussie is producing under licence in near Melbourne) is not going to be sufficient to get herd immunity.

It is not known if herd immunity occurs at any level of covid vaccination. In the covid case we know vaccination prevents symptoms and death - we don't know if immune people are also non-infectious at this time. Therefore vaccination effect on R value is not known, as explained by @sbiddle in an earlier post.

Imo it's likely there is some effect on R value based on reducing severity of symptoms but personally I have no real idea about this.

You are correct that it has yet to be proven if the covid-19 vaccinations prevent a person from being a vector for the virus. However it seems like there is a reasonable chance it does, and my analysis was based on that it does (should have listed it as an assumption).

That said, in the (unlikly in my view) event that all the covid-19 vaccines just prevent symptoms (hence sickness & death), but not the spread, then it would be very important for us to select high efficacy vaccines from a human health perspective. With the vaccine masking who are carriers, the virus could cut through our community quickly, and there is a big difference between having 70% and 95% efficacy vaccine in those circumstances.

There also is a chance that some vaccines prevent spread, and other's just stop symptoms. If this situation is discovered, it may be a good play for NZ to only use the ones that prevent spread, even if it means delaying our vaccination timeline.

Thats correct. But it was stay at home, walk at the park, no work unless essential.

Furthermore, if you had:

UK focusing on just the economy and low measures, the Bell Curve will slowly evolve and then hit the upright curve, as has happened.

Better measures but still with holes, the Bell Curve is merely delayed, but you still have issues, as AUS has had, but at least they had measures so they were able to cope with it, and they still have outbreaks.

NZ version, where its very very difficult to reach the upward spike of the Bell Curve, so MIQ flouters, the odd hole are infrequent and dealt with.

If you want to help the economy you focus ONLY on the virus. Having a help the economy model and please wear a mask doesn't work. Masks and other measure do work, but not with holes galore. Please stay home but you can go to work and get your nails done, doesnt work. In NZ we ended up with long nails and long hair but no Covid.

Think you will find was also no returnees. international travel was all but ceased, Hence repatriation flights later arranged to deal with them

I was still working on campus at lvl4. Airport staff were being laid off, and customs officers used for lockdown checks due no planes as airlines crumbled from cancellations.

Remember the govts motorhomes scheme at the military camp.. where they had no cell coverage.. that was still an miq before hotels.

The headline should read “via” Auckland airport , the passengers did not originate in NZ ,

The story’s title is sensationalist at best, dishonest at worst

All of the media reports on that yesterday were pretty terrible and based solely on the Fiji media release. Don't fall for the clickbait headlines.

Both cases were transit passengers through Auckland, they didn't originate in Auckland. One key thing that the Stuff story (and certainly the other news stories I read, heard and watched yesterday) didn't mention is that the same flight had a positive case reported on the 6th who had flown from the UK

https://www.rnz.co.nz/international/pacific-news/434122/four-new-cases-of-covid-19-in-fiji

So you're looking at a possible case of transmission that occurred before / during / after the flight with the UK passenger.

Or facility origin. Reported on am show as it was their pre-release test after a similar multi check regime to our own?

Interested to know what sort of transit protocols there are within the airport (had to be masked when travelling domestically within the terminal when I went to Queenstown last year) and how an infected transiting passenger risk is minimised when it comes to surfaces, airport staff, etc - presumably the airport staff are considered 'border workers' and tested regularly?
