▪️Changes in health status following SARS-CoV-2 infection are common and can occur at any age.
▪️Symptoms are frequently experienced for months or years and can increase over time.
/2
▪️Future health impacts can be expected in addition to the effects that are already observed.
▪️ Some people who are currently well post-Covid are already expressing biomarkers of risk for cardiovascular disease, neurodegenerative disorders, autoimmune diseases & cancers.
/3
▪️Society, sector & workforce effects of Long Covid are costly and disruptive, and they worsen existing inequities.
▪️ The frequency of (often undiagnosed) cognitive impairment after a mild infection indicates a need for risk assessment of impacts on occupational safety.
/4
▪️Because of rapid viral evolution, Covid-19 waves are not showing a consistent pattern of improvement over time.
▪️Without intervention to reduce cases, the prevalence of Long Covid is more likely to increase than to decrease.
/5
▪️When an infectious disease is common in the population, its long-term effects become common too.
▪️At a population level, modest-looking proportions of a post-infectious health risk readily translate into very large numbers.
/6
The report concludes that:
“Our evidence summary strongly suggests that Long Covid is a major threat to individual health, societal wellbeing and economic performance.”
/7
The Appendix of the report expands further on this important point:
“Choosing to ignore potential harms is indefensible when the risk can be reduced using a combination of new knowledge and well-established public-health approaches.”
/8
The authors recommend 3 immediate actions:
▪️Conducting a comprehensive Long Covid risk assessment.
▪️Rapidly reduce infection & reinfection rates using well-established public health & social measures.
▪️Expand Covid-19 vaccine eligibility and coverage.
/9
Appendix 2 provides further details of the proposed components for Covid mitigation, including:
▪️Support for self-isolation of infected cases
▪️Improve indoor air quality
▪️Maintain mask use in high-risk indoor environments eg health care
▪️High & equitable vax coverage

Below is a press article about this report, highlighting the fact that, in terms of occupational risk, teachers are the most vulnerable to getting Covid - and, in turn, most at risk of getting Long Covid.
Below is another press article which includes comments from NZ Education Institute president Mark Potter.

Potter revealed that his union had heard from a lot of teachers who were struggling to continue in the profession due to Long Covid.
The chart of Covid case rates by occupational group can be found in the chart below, showing that teachers are at significantly higher risk of Covid infection than any other occupation.
One of the authors, @AmandaKvalsvig, tweeted earlier that schools MUST be made safe since they’re the hubs of their communities, linking public settings & households.
The only effective way to reduce Long Covid is to reduce Covid cases.
This report is a truly outstanding piece of work and could form the blueprint for ANY government willing to confront the enormous health & economic challenges presented by repeated Covid infections and the resulting impact of Long Covid.
Meanwhile, in the UK 🇬🇧, a paper was recently published by @CambridgeEcon on the economic burden of Long Covid.
The report estimates that, if the UK prevalence of Long Covid increases to 4m people by 2030, there will be a £2.7 BILLION loss in GDP & 311k job losses PER YEAR.
This is not a particularly new idea; it’s been discussed in scientific circles for years already.
Back in early 2023, the World Health Network (@TheWHN) published this article which summarised the latest research on Covid’s impact on the immune system.
The guidance is clear that those self-isolating at home should NOT wait for symptoms before taking precautions.
For the ENTIRE 42-day quarantine, they should:
▪️Avoid contact with other household members
▪️Remain in a separate room
▪️If contact is unavoidable, wear a respirator
🚨Clinically Vulnerable Families (@cv_cev) have issued a press release calling for the government to immediately publish the full operational & clinical arrangements for passengers & close contacts linked to the MV Hondius outbreak.
I’ve just listened to the health update from the US Nebraska Health Officials 🇺🇸
A few points of interest:
1/ in addition to the US passenger who tested positive & the one showing symptoms, it seems there is ANOTHER passenger who may have tested positive.
2/ Passengers currently in the Nebraska quarantine unit will spend a few days there being assessed.
If they remain symptom free & have support available at home to isolate safely, they’ll have the choice to complete the 42-day isolation either at home or in the quarantine unit.
3/ When asked about the US passengers who left the ship in St Helena on 24 Apr (at the same time at the Dutch woman who was symptomatic & sadly died on 26 Apr), they confirmed that these passengers have all been traced & are being monitored - but seems they’re NOT self-isolating.
Following my thread yesterday which criticised aspects of the WHO’s strategy, I’m pleased to see they’ve done a 180° turn in the updated guidance published today:
…and ALL high-risk contacts will now be required to ISOLATE in a designated facility or at home (depending on each country’s capabilities) for 42 days from last known exposure…
…and for the MV Hondius passengers & crew, the last day of exposure is the date of disembarkation.
So for the passengers & crew leaving the ship today, the clock for their 42 days in isolation starts ticking TODAY…
…and their isolation & monitoring will end on 21 June.
Following the WHO press briefing, I wanted to compile a thread with the key points.
1/ ISOLATION OF PASSENGERS
Concerningly, it seems the WHO are NOT recommending to isolate cruise ship passengers (even high-risk contacts) UNLESS they develop symptoms.
Just to quickly recap, it has been confirmed that the passengers & crew (including the 30 who disembarked on 24 April in St Helena) come from a total of 28 different countries.
The full breakdown of countries for both passengers 🟥 & crew 🟦 is detailed below ⬇️
When the 146 people remaining on the ship are repatriated to their home countries, each country will adopt their own local protocols.
