I’ve been delighted to see the sudden surge in support for mandatory hotel quarantine (MHQ) in Ireland, with the aim of achieving zero covid. While it is, on balance, the best option, I fear that some commentators have underestimated the challenges. Here are some examples....
...1) MHQ is frequently framed as a temporising measure, with the aim of establishing quarantine-free travel bubbles with other zero covid regions. Not many countries have achieved zero community transmission. But in those that have, travel bubbles have been vanishingly rare...
...2) MHQ is super strict. The point of it is that it would allow Ireland to open up society again. If you miss cases in that context, you let infectious people into a country where socialising is the norm. The result is explosive outbreaks. In countries that have MHQ, you...
....don’t get exemptions except in the rarest cases. Not for funerals or sick relatives or graduations. Exemptions in most MHQ countries allow you out for a few hours at most on only the most compassionate grounds. If it’s too loose, it just doesn’t work.....
3) You still get occasional outbreaks and cases. The aim is for zero community transmission, not zero cases. If a covid+ve person in MHQ sneezes on a surface enroute to their room for example, you could get fomite transmission to a staff member. Quarantine hotels in themselves...
...have been the source of most outbreaks in zero covid countries because that’s where all the cases are. Infection control has to be scrupulous, but will never be perfect....
4) It only really ends when you have herd immunity from vaccination. It’s not quick and it’s not temporary. You can’t postpone MHQ for paddy’s day or Easter. If you do, you’ll see a rapid spike in cases very very quickly....
...MHQ is not a good thing. It’s the least bad choice in a selection of pretty bad choices. I have a 3 week old baby who won’t meet his grandparents or aunts and uncles until xmas at the earliest. But when faced with the choice between recurring lockdowns that serve no real....
....purpose, and MHQ with all it’s challenges, it’s no contest for me. I cant imagine any Australian or New Zealander would rather things were more like Europe. But with momentum growing for zero covid, I just think everyone should be aware of exactly what it takes to make MHQ..
....work. Denying people their liberty is a big deal and should never be taken lightly. But seeing elderly people afraid to leave their houses back home and kids being out of school, it’s DEFINITELY the best option.

Getting the whole world vaccinated against covid MUST be a priority. It’s unconscionable that close to zero people in low-income countries have been vaccinated so far. This is important to absolutely everybody for three reasons...
...1) The ethics of only vaccinating a quarter of the planet should be unthinkable to us. 2) For many reasons, we will have vulnerable people who are not protected by the vaccine, now and in the future. These people will be at risk on an ongoing basis from imported cases if...
...the virus continues to circulate globally. 3) The longer the virus thrives, the higher the chance of mutations, which could make any vaccine less effective or ineffective....

My favourite thing about this week is that the Irish government went to outbreak school 😂 Naturally, the department of finance and Ernst&Young led the teaching. Public health weren’t needed because they had “data guys” instead.....
...The department of finance led with this cracker. Their advanced data mining revealed the presence a link between health, economics and society....
.....This graph has since been used to estimate the ideal number of deaths in a population. Hat tip to @conorsmith .....

I know a thread on a contractual issue is never going to be one of the greats. But my Irish colleagues might take industrial action and it’s important to tell people why, before inevitable political mudslinging starts. This issue is about pandemic safety, so I’ll try to explain..
....in Ireland, when you finish medical school, you can go on and do specialty training. It takes years and there are lots of awful exams, but you get there in the end and you qualify as a consultant. And then the @HSE_HR give you a consultant contract. Except for public health..
....Decades ago, someone in the dept of health decided that public health doctors were so useless as to require unique treatment and an individual contract. This was called a “specialist” contract, and was generally just a crappy version of a consultant contract. It meant you...

The pandemic response in Ireland has understandably led to quite a bit of confusion and things are changing rapidly, from lockdowns to school closures. So I thought I’d write a thread on what might, and might not, work well in a country like Ireland with over 1000 cases per day..
..Recurring lockdowns don’t work. Well, it depends on what you mean by “work”. They’re v good at getting cases numbers low. But they don’t change any of the underlying conditions that allowed the virus to multiply in the first place. So, once society opens up, cases go up again..
..I’m slightly concerned that people are being fed a narrative that reads “if we do this lockdown right, we can stop this virus”. It may well get us low cases for Xmas, but I’d anticipate another lockdown around Easter, though I hope I’m wrong about that...

Five things I’ve done in the last year as a public health doctor that, like most of what we do, flies under the radar....
1) Our surveillance system found disease-causing mosquitoes in an area where they shouldn’t be. We developed a plan to eradicate them, which we did, and followed up with continued surveillance to make sure they were gone. Nobody became unwell.
2) Managed a pertussis (whooping cough) outbreak in a shelter for a vulnerable population with quite a few very young babies living there. After we implemented the outbreak management plan, nobody else became unwell.

In trying to make sense of what might seem like confusing or inconsistent decisions around #COVIDー19 interventions at the population level it might be helpful to look at the different phases of a pandemic and what type of control measures happen during each phase. This is....
....the Australian pandemic plan. It’s publicly available. Ireland will have a VERY similar plan, though the names of the phases might be different. PHASE 1: Preparedness; This is when planning happens. It’s ongoing, with meetings, desktop exercises and pressure testing.....
.....PHASE 2: Standby; This phase kicks in when there’s sustained transmission overseas. When China saw the situation get bad, most countries stepped into this phase. It’s enhanced level of preparation. Lots of banal work goes on behind the scenes, from making sure local plans...
