The DG said we were supposed to get the results of the cold storage test on Sunday, then Monday afternoon. I wonder why it keeps getting pushed back.

Extra time needed to culture up the samples??..

There is certainly likely to be much less viral load on a very old cold surface than a nice warm juicy throat...

I believe they were waiting for genome from Aus, but I expect the entire report probably includes results of testing surfaces at the Akl Americold facility. When looking for very small traces then the chance of getting intact RNA is reduced - the chance of adding errors is greater - making it harder to establish if it matches.

The big question is already answered - The cluster here is not the same as the C-19 contracted by the Americold worker in Melbourne.

Hemi88: What’s the point of the reporters giving the same questions over and over again it’s been answered multiple times testing was in place it was voluntary it’s was taking time to ramp up now it will be mandatory from now on

They issue is that the public was falsely lead to believe that a comprehensive testing program was in place at front line workplaces (rather than ramping up), and they are looking for a damming quote that they can use in articles covering that.

It sounds like the voluntary / compulsory testing thing is a bit of a red hearing, as there were accounts of people (bus drivers etc) requesting testing prior to the current drama and being declined.

I just think it’s been answered and it’s been made more clear and fixed were it needs to be and there is others question to be asked

Hemi88: all of the staff at ridges have been tested and comeback negative a surface could be a problem

not yet.

Still some tests to do

", however as a precaution all staff and returnees at the Rydges are being retested again via an onsite testing team. Forty-five staff members and 54 guests were tested yesterday, the remainder will be tested today."

https://www.health.govt.nz/news-media/media-releases/results-covid-19-positive-cases-under-investigation-returned

Yes, but if it was a surface, it will never be known as they place has subsequently wiped clean.

I think it was mentioned that they can tell the number of steps between cases via Genomic testing,

But they are still waiting on the full test to come back, the announcement today was based on a " partial genome sequencing"

As things have played out today, it appears that the specified testing around the border staff and facilities wasn't in place on June 23rd, and was only in the process of being rolled out. More info at https://www.stuff.co.nz/national/health/coronavirus/122473901/coronavirus-ashley-bloomfield-blames-miscommunication-for-quarantine-testing-confusion and https://www.newshub.co.nz/home/new-zealand/2020/08/chris-hipkins-admits-tracking-system-for-border-workers-wasn-t-in-place-before-testing-strategy-announcement.html

Potentially lot of holes for the virus to find a route into the community during that time, and it appears it took advantage of a hole late August. Very important we find the source of the hole for our elimination strategy to continue, and to prevent a repeat of the virus entering in the same way again. At least they are being tested now, and luckily this outbreak looks like it is somewhat contained based on the cases so far. But it can take weeks to know for sure, and hopefully we don't get random cases popping up in other parts of NZ, even if linked to the cluster, otherwise we could have a very long tail in level 2 .

unless you are going to test the border staff daily and make them go into isolation until they do come back negative then testing them weekly or so will be a waste of time. You can be tested Monday and show a negative test and by Thursday you could be positive and walking around because your Monday test showed a negative result. You may catch a few but it wont catch everyone . Maybe more for peoples peace of mind.

Yes you will catch a few and this has been proven by the positive test today which possibly may not have been detected if we hadn’t had this outbreak Which has prompted more testing at the border. It reminds me of the situation we had when we started mandatory testing on people returning to NZ , when prior to this we weren’t getting many cases being picked up at the isolation facilities for a long period. Then when this testing commenced we were getting new cases daily. As I have been saying for months here after seeing the poor testing numbers, testing is the key. The test numbers being performed up until a week ago don’t appear to have been up to the level that the minister required , which was 4000 tests a day.

Hemi88: @wellygary there was health checks which would of included temp checks where the breakdown from gov and moh I think is with the swab test which were irregular instead of every time

Temperature checking is not a suitable alternative to a test and the MOH said previously that they weren’t using it on inbound travelers because of this earlier on the year.
It does also say that positive worker had a cough but passed the health check prior to being tested which goes to show that tests are the best way to do it.

Also I see they have now ruled out the cold store as the source which is both good and bad news

Yes but they were also then not testing the people coming through isolation either. So.....

at lest it been fixed now and still with a couple loose chains which have been fixed I wouldn’t want to be anywhere else in the world right now and so far with gnome testing done there still is no link to the border so far 🤞

Now one separate case that is ex quarantine facilities

i wonder how many such cases we've missed in the last few months

I don't think that it is especially important we find the source. If the source is a person, it is likely they got better some time ago, and as such no longer contagious. Massive amounts of community testing, combined with level 3 in Auckland reduce the odds of any unidentified transmission.

In terms of finding the source to plug the hole it came in through, if anything, not finding the source, and doing a full audit on holes will result in a far better outcome.

We already know that this rush of public interest has resulted in huge hole being identified, with regards to the public being incorrectly advised that all border workers were being tested.

There are still heaps more holes to plug:

Offshore based air crew (who get bused to normal hotels, told not to leave their room etc.). The general public share these hotels, and they don't have the security, hygiene, or staff testing of the isolation facilities. It is pretty obvious these people should at minimum in a managed facility, or in a camper van village air-side at the airport.
NZ based air-crew. It's crazy that the politicians can stand at the podium immediately after announcing the maintenance worker case (who was postie despite objectively low risk, and correct following of procedures), and say that NZ based aircrew don't need isolation because of their procedures despite objectively massively higher risk. A conflict with testing requirements published was also identified today.
Diplomatic exemption from managed isolation - other countries have had (multiple times) issues with diplomats.
Marine crew exemption: - the rules around this are too loose. Domestic flights need to be disallowed, and any internal transfer needs to be arranged by the government and be carried out in a minimal risk way, rather than letting the shipping company or crew member do it.
Managed isolation: - risks of infection being passed by the likes of a contaminated elevator need to be manged. - risks of people coming into contact with each other requiring a reset of the 14 days (of a positive case is identified) after a fire alarm etc.
Domestic transfer flights of those in managed isolation - needs to be managed. The crew are required to hand out lollies and water, and then go straight onto other domestic flights FFS.

We will never know, but if we have had COVID leaking out, then we have been exceptionally lucky because we have not had any other clusters flair, and (this case excluded) all the community COVID being found is related...

On the plus side, the number of cases don't seem to be rising exponentially.... and the effect of the lock down should start to be seen in he next few days... but unless there is a rapid decline, I think Auckland could be in for Level 3 until at least the end of next week....

There appears to be quite some variability in the level of contagiousness.

We could have got lucky several times.

The odds of picking up the first such case days after rolling out widespread testing seem low.

I don't think that's got anything to do with functional variation in the virus since the D614G mutation - which is everywhere. It's got everything to do with human behaviour, where people went, what they did etc.
