COVID-19 Helping people check locations of interest

• locations of interest,
• New Zealand

OPINION. It’s important locate as many people who have been at locations of interest as possible in New Zealand’s Delta variant outbreak. Because few people have been scanning QR codes or keeping other personal records we’re relying on people to check the Ministry of Health’s list of locations of interest. A few initiatives might help this. People who’ve been at … Read More

COVID-19 The rise and rise of Delta

• Delta variant,
• New Zealand,
• Sydney

From media headlines it feels like hearing the boy cry “fire” in the theatre. There’s a new variant about. Or perhaps he is really a crier, calling out a new season of the show, a new plot twist with a craftier villain? The main feature in town is now the variant Delta—B.1.617.2—and its closest staging to us is a so … Read More

Attempt to stop NZ vaccine rollout declined, government to pass new bill

• High Court,
• Sue Grey,

The High Court has declined an attempt to halt New Zealand’s vaccination rollout. It does asks the Crown to consider how their plans sit within current law. The government plans to pass a Bill under urgency today to tackle this. I think a fair question is if the deeper issue lies with a lack of mechanism for emergency use approval in … Read More

Many people seem to be reading that our COVID-19 vaccine won’t prevent the spread of COVID-19 from one person to the next.1 If you’re worried about this, this one is for you. We now have evidence the vaccine reduces transmission, and a rough idea of by how much.2 Science is often about pulling different pieces of evidence together, in this … Read More

Blood clots, vaccines and the need for baselines

Some nations are pausing their AstraZeneca COVID-19 vaccine campaigns over concerns that it may be linked to blood clots. International media is is reporting it widely. I’m seeing concerned people asking questions on social media. Evidence so far indicates this is unlikely to be a real issue, but one that is being checked out of caution. One thing it illustrates … Read More

B.1.1.7 variant – early result suggests longer infections, management questions

Sometimes it’s smaller, intensive studies that shed light on issues. Just reported results of daily sampling of COVID-19 patients indicate patients with the B.1.1.7 variant first observed in Kent, UK may have a longer infection compared to patients infected with non-B.1.1.7 variants. This is the variant seen in NZ’s most recent outbreak in Auckland. If this observation bears out in … Read More

New Zealand has been called out as an outstanding player in managing COVID-19. We’ve done well,[1] but we’re far from perfect. We could do a lot better at backing our front row. Epidemiologists advise nations not to play “wait and see”. If By the time they do see, it’s all over them. “She’ll be right”… until it isn’t. We’re less … Read More

COVID-19: sequence the viral genomes of all border cases

New Zealand has an advantage in managing COVID-19: all our cases come from the border, one way or other.[1] We can exploit this in how we shut down outbreaks. One way is to have at the ready the viral genomes of all border cases. With this we can quickly find the starting point of any outbreaks inside the country. If … Read More

Is 2019-nCov a pangolin coronavirus?

• 2019-nCov,
• coronavirus,
• pangolin,
• Wuhan

Tonight’s news suggests the coronavirus outbreak may have originated from pangolins. Details are very sketchy, almost nothing at all beyond a claim of high similarity. My impression is this claim comes from a press release by South China Agricultural University. Initial discussion online suggests this is a more likely candidate for an intermediate host than previous speculations. It is also … Read More
