The news about New Zealand’s “massive Covid outbreak” needs context. After over 100 days of daily life with zero new cases other than those sequestered at the border quarantine facilities, during 14-21 August 2020, New Zealand had a "big surge" in Covid-19 number of total cases and those requiring hospitalisation of 500%. In real numbers, the number of cases rose from approximately 20 to 100 and the number of people requiring hospital care increased from 1 to 5. By comparison, South Carolina, a state in the US close to New Zealand in population, had 5,537 new cases and 255 deaths the same week. In the history of the pandemic, New Zealand has had approximately 1600 cases and 22 deaths, versus South Carolina's 110,000 cases and 2500 deaths. (www.worldometers.info/coronavirus/country/us)
The origin of New Zealand's index
case of community transmission – a worker at a cold storage facility, has not
yet been determined, but rigorous scientific testing is being performed to rule
out sources. It does not have the same genome as New Zealand’s earlier cases,
nor does it match the genome of any of the recent overseas arrivals in the
managed isolation quarantine facility.
I am living in
Auckland, the country’s largest city that was put in lockdown last week with
less than 24 hours’ notice, closing non-essential businesses, reducing cafes
and restaurants to take-out only, and further restricting movements and gatherings.
Schools are open for children of essential workers, but parents are encouraged
to keep kids at home if possible. With this lockdown, the government also asked
the public to wear masks in public places, such as public transportation or
grocery stores.
How are we doing? Quite
well, following the testing, tracing and communication advice from the experts:
TESTING - Our Covid testing quickly ramped up from an average of 5,000 per day prior to the four cases of community transmission identified on 11 August 2020 to an average of over 17,000 per day. The testing has focused on cluster areas with known contacts of positive cases, and results each day have yielded less than 0.1% positive, versus the average of 6.7% positive tests in the US.

A world map with percentages of positive test
results is offered by https://ourworldindata.org/coronavirus-testing (see below). This metric is used by public health officials to determine
opening of businesses and schools. From this site: "According to criteria published by WHO in May, a positive rate of less
than 5% is one indicator that the epidemic is under control."
The US 7-day average rate is reported on this date to be 6.7%, worse than Romania. Remarkably, the US infection rate on 15 July (prior
to the data being reported through the White House) was 8.4%. Without any
specific intervention, the US improved considerably in four weeks, just in time for schools to re-open.
TRACING - The NZ tracing team followed up on thousands of contacts during the week after the virus re-appeared in the community. Most of the cases identified this week in New Zealand had been identified as contacts to the original case, so they were already isolating when they tested positive.

COMMUNITY ENGAGEMENT - From the beginning the Prime Minister has led with the message, “our team of five million is fighting the virus”. The hashtag message #BeKind has been visible on the interactive motorway signs, supermarket entrances, and written in chalk on walkways by neighbourhood children. New Zealanders are reminded to be kind to one another and to check on their neighbours frequently during the daily Covid updates from the Ministry of Health.
The team of five million is engaged in this. For the second wave, in one week wearing masks in public places changed from less than 5% to about 90% (source: my poll at the supermarket).
MANAGED ISOLATION QUARANTINE (MIQ) - Kiwis returning to New Zealand are required to stay 14 days in a managed quarantine facility. This has been an evolving story. Originally those arriving in New Zealand from overseas were told to go home and self-isolate. That didn’t work very well as many did not adhere to staying at home, so the government set up the managed facilities and required all overseas arrivals to stay 14 days before heading on their journey. Those in the quarantine facility are tested for Covid at about Day 3 and Day 12 of their stay. This had more success in containing the virus, but in the early days the administration at these sites was porous in their enforcement of the rules, mostly granting exceptions for compassionate reasons. In one case, two sisters were granted early leave of the facility to see their dying relative, but soon discovered they had tested positive. As a result, the independent contracting agency was replaced with the army who has a bit more reverence for following rules. Had the facility management started with the army, the tactic would have been perceived as too authoritarian and heavy-handed, but after the breaches it had the public’s support.
ICELAND
New Zealand is not the only country to be living
without the ubiquitous threat of Covid within the community. Iceland has done
well, with the same formula of testing,
tracing, and communication. Interestingly, their leadership trio reporting
daily consists of a doctor, an epidemiologist, and a police detective for the
tracing part. Politicians have deferred the country’s Covid management to these
three experts.

Iceland is back to enjoying life in spa pools,
restaurants and bars. Like New Zealand, the only thing missing are the
tourists. Though also like New Zealand, Icelanders are known to spend time and
money overseas and they are spending it domestically this year.
Iceland’s border policy differs from New Zealand’s.
As of 19 August 2020, all travelers to Iceland may choose to submit to two
screening tests, separated by five days’ quarantine until the results of the
second test are known, or not undergo screening test at the border and spend 14
days in quarantine after arrival. The quarantine location is up to the
individual, with Iceland Immigration’s website providing specific rules. This
is riskier than New Zealand’s mandatory 14-day quarantine, but Iceland feels
confident they are able to reasonably contain and manage with their testing and
tracing activities which also features a public tracing app, and their healthcare system.
Taiwan is still determined to do better, and they are looking at improvement opportunities in their communication with the public. Though they provided frequent updates, they feel they could have done better at preparing the public for this pandemic by providing more information on prevention and how people should stay safe. Unfortunately, Taiwan has been excluded from the World Health Organisation because China claims Taiwan as its province with no right to their own diplomatic representation on the global stage and in international organisations. As a result, Taiwanese health officials say they were left out of receiving early firsthand information on the Coronavirus outbreak, and very unfortunately for the rest of the world, Taiwan's success story was unable to be shared.
Well done, Barbara.
ReplyDeleteEspecially remarkable in your data is Taiwan, which has achieved this success despite its population density, a factor that's too often overlooked. People insult New York's statistics compared to Seattle's, without noting that there's an eightfold difference in density for both the downtown areas and the larger metropolitan areas. I don't know how that affects the contagion equations but it certain points to the power of Taiwan's approach.
Some of us in the US (as I imagine you know) fear that the catastrophic failure of Trump's response has put him in a political corner from which he may only have one route of escape, in his desperate search to retain power: martial law, because even his potent BS skills aren't persuading enough people to believe him anymore. I expect this will become an important, historic lesson on the societal consequences of ignoring science, which is just another name for ignoring reality.
