Why declaring monkeypox a global health emergency is a preventative step — not a reason for panic

By late July 2022, monkeypox was present in more than 70 countries with significant spread in certain communities. As a result, the World Health Organization…

Countries that are members of the United Nations are obligated to report cases of unusual diseases that have the potential to become global health threats. In May 2022, more than a dozen countries in Europe, the Americas and other regions of the world that had never before had cases of monkeypox started to report cases occurring within their borders.

In response, the director-general of the World Health Organization, Tedros Adhanom Ghebreyesus, convened a monkeypox emergency committee to track the evolving situation. At the committee’s first meeting on June 23, 2022, the members observed that the “multi-country outbreak” might be stabilizing as case counts had plateaued in several countries.

However, after thousands more cases of monkeypox were diagnosed in dozens of countries in July, it became clear that the outbreak had not stagnated. On July 23, 2022, Tedros declared monkeypox a public health emergency of international concern.

As a global health expert who specializes in infectious disease epidemiology I do not think that most people need to be worried about monkeypox. This decision by the WHO, though it may sound ominous, is not a sign of bad things to come. Rather, it is a way to prevent monkeypox from becoming a global crisis.

What is a public health emergency of international concern (PHEIC)?

The International Health Regulations are a set of rules that guide how the WHO and United Nations member states respond to emerging health threats.

Under the current regulations, a “public health emergency of international concern” – often abbreviated as a PHEIC – can be declared by the WHO director-general when three criteria are met: the situation is an “extraordinary event,” there is a risk of spread to other countries, and the situation might “potentially require a coordinated international response.”

Before monkeypox, only five diseases had been designated as PHEICs since the WHO started using the term in 2005: the H1N1 influenza pandemic in 2009; polio resurgences in Afghanistan, Nigeria and Pakistan in 2014; the Ebola epidemic in Guinea, Liberia and Sierra Leone in 2014 and an Ebola outbreak in the Democratic Republic of Congo 2019; the spread of Zika virus in the Americas in 2016; and the coronavirus pandemic in 2020. While all of these events were noteworthy, only the coronavirus pandemic became a worldwide catastrophe.

Why is monkeypox a public health emergency of international concern?

The director-general of the WHO is the only person who can declare a PHEIC, but the decision is based on advice from the designated emergency committee. After the monkeypox emergency committee met for the second time, on July 21, 2022, it released a report stating that “the multi-country outbreak of monkeypox meets all the three criteria defining a PHEIC.”

The rapid spread of the virus to more than 70 countries was evidence of the risk of further international spread. The committee expressed concerns about whether vaccines would be priced reasonably and distributed equitably in the absence of a coordinated international response. And it agreed that there were aspects of the situation that were “extraordinary” – a vague term that is not defined in the International Health Regulations.

However, the committee did not express unanimous agreement that a public health emergency of international concern should be declared. Some members questioned whether a disease that has a low case fatality rate should be a PHEIC. Others worried that a PHEIC designation could further stigmatize LGBTQ communities since most cases thus far have been diagnosed among men who have sex with men.

The vote from the emergency committee was split – nine against and six for PHEIC status. But Director-General Tedros opted to go ahead and declare monkeypox a PHEIC.

What happens now?

The goal of a PHEIC designation is to prevent an emerging disease from becoming a global health crisis. The WHO has two initial goals for monkeypox. First, to try to stop the virus from beginning to circulate in susceptible populations where it is not currently present. And second, to distribute vaccines and antiviral medications to the countries and communities that need them most.

After the PHEIC declaration, the WHO released a set of temporary recommendations that asks countries to work harder on preventing cases in affected and at-risk communities, to improve clinical care for people with monkeypox and to contribute to research on vaccines and treatments for monkeypox. The recommendations also ask countries to advise infected individuals and their direct contacts not to travel except in urgent situations, but they do not impose any restrictions on international travel or trade.

Finally, the WHO has advised that individuals who are members of at-risk communities take steps to protect themselves from the virus, but has not called for changed behavior in the general public.

A public health emergency of international concern is the highest level of alert in the International Health Regulations, but it is not a synonym for a pandemic. The status is a tool for protecting global population health and not a declaration that a global crisis is already happening.

The next pandemic? It’s already here for Earth’s wildlife

Bird flu is decimating species already threatened by climate change and habitat loss.

I am a conservation biologist who studies emerging infectious diseases. When people ask me what I think the next pandemic will be I often say that we are in the midst of one – it’s just afflicting a great many species more than ours.

I am referring to the highly pathogenic strain of avian influenza H5N1 (HPAI H5N1), otherwise known as bird flu, which has killed millions of birds and unknown numbers of mammals, particularly during the past three years.

This is the strain that emerged in domestic geese in China in 1997 and quickly jumped to humans in south-east Asia with a mortality rate of around 40-50%. My research group encountered the virus when it killed a mammal, an endangered Owston’s palm civet, in a captive breeding programme in Cuc Phuong National Park Vietnam in 2005.

How these animals caught bird flu was never confirmed. Their diet is mainly earthworms, so they had not been infected by eating diseased poultry like many captive tigers in the region.

This discovery prompted us to collate all confirmed reports of fatal infection with bird flu to assess just how broad a threat to wildlife this virus might pose.

This is how a newly discovered virus in Chinese poultry came to threaten so much of the world’s biodiversity.

The first signs

Until December 2005, most confirmed infections had been found in a few zoos and rescue centres in Thailand and Cambodia. Our analysis in 2006 showed that nearly half (48%) of all the different groups of birds (known to taxonomists as “orders”) contained a species in which a fatal infection of bird flu had been reported. These 13 orders comprised 84% of all bird species.

We reasoned 20 years ago that the strains of H5N1 circulating were probably highly pathogenic to all bird orders. We also showed that the list of confirmed infected species included those that were globally threatened and that important habitats, such as Vietnam’s Mekong delta, lay close to reported poultry outbreaks.

Mammals known to be susceptible to bird flu during the early 2000s included primates, rodents, pigs and rabbits. Large carnivores such as Bengal tigers and clouded leopards were reported to have been killed, as well as domestic cats.

Our 2006 paper showed the ease with which this virus crossed species barriers and suggested it might one day produce a pandemic-scale threat to global biodiversity.

Unfortunately, our warnings were correct.

A roving sickness

Two decades on, bird flu is killing species from the high Arctic to mainland Antarctica.

In the past couple of years, bird flu has spread rapidly across Europe and infiltrated North and South America, killing millions of poultry and a variety of bird and mammal species. A recent paper found that 26 countries have reported at least 48 mammal species that have died from the virus since 2020, when the latest increase in reported infections started.

Not even the ocean is safe. Since 2020, 13 species of aquatic mammal have succumbed, including American sea lions, porpoises and dolphins, often dying in their thousands in South America. A wide range of scavenging and predatory mammals that live on land are now also confirmed to be susceptible, including mountain lions, lynx, brown, black and polar bears.

The UK alone has lost over 75% of its great skuas and seen a 25% decline in northern gannets. Recent declines in sandwich terns (35%) and common terns (42%) were also largely driven by the virus.

Scientists haven’t managed to completely sequence the virus in all affected species. Research and continuous surveillance could tell us how adaptable it ultimately becomes, and whether it can jump to even more species. We know it can already infect humans – one or more genetic mutations may make it more infectious.

At the crossroads

Between January 1 2003 and December 21 2023, 882 cases of human infection with the H5N1 virus were reported from 23 countries, of which 461 (52%) were fatal.

Of these fatal cases, more than half were in Vietnam, China, Cambodia and Laos. Poultry-to-human infections were first recorded in Cambodia in December 2003. Intermittent cases were reported until 2014, followed by a gap until 2023, yielding 41 deaths from 64 cases. The subtype of H5N1 virus responsible has been detected in poultry in Cambodia since 2014. In the early 2000s, the H5N1 virus circulating had a high human mortality rate, so it is worrying that we are now starting to see people dying after contact with poultry again.

It’s not just H5 subtypes of bird flu that concern humans. The H10N1 virus was originally isolated from wild birds in South Korea, but has also been reported in samples from China and Mongolia.

Recent research found that these particular virus subtypes may be able to jump to humans after they were found to be pathogenic in laboratory mice and ferrets. The first person who was confirmed to be infected with H10N5 died in China on January 27 2024, but this patient was also suffering from seasonal flu (H3N2). They had been exposed to live poultry which also tested positive for H10N5.

Species already threatened with extinction are among those which have died due to bird flu in the past three years. The first deaths from the virus in mainland Antarctica have just been confirmed in skuas, highlighting a looming threat to penguin colonies whose eggs and chicks skuas prey on. Humboldt penguins have already been killed by the virus in Chile.

How can we stem this tsunami of H5N1 and other avian influenzas? Completely overhaul poultry production on a global scale. Make farms self-sufficient in rearing eggs and chicks instead of exporting them internationally. The trend towards megafarms containing over a million birds must be stopped in its tracks.

To prevent the worst outcomes for this virus, we must revisit its primary source: the incubator of intensive poultry farms.

A major cruise line is testing a monthly subscription service

The Cruise Scarlet Summer Season Pass was designed with remote workers in mind.

Published

While going on a cruise once meant disconnecting from the world when between ports because any WiFi available aboard was glitchy and expensive, advances in technology over the last decade have enabled millions to not only stay in touch with home but even work remotely.

With such remote workers and digital nomads in mind, Virgin Voyages has designed a monthly pass that gives those who want to work from the seas a WFH setup on its Scarlet Lady ship — while the latter acronym usually means "work from home," the cruise line is advertising as "work from the helm.”

"Inspired by Richard Branson's belief and track record that brilliant work is best paired with a hearty dose of fun, we're welcoming Sailors on board Scarlet Lady for a full month to help them achieve that perfect work-life balance," Virgin Voyages said in announcing its new promotion. "Take a vacation away from your monotonous work-from-home set up (sorry, but…not sorry) and start taking calls from your private balcony overlooking the Mediterranean sea."

This is how much it'll cost you to work from a cruise ship for a month

While the single most important feature for successful work at sea — WiFi — is already available for free on Virgin cruises, the new Scarlet Summer Season Pass includes a faster connection, a $10 daily coffee credit, access to a private rooftop, and other member-only areas as well as wash and fold laundry service that Virgin advertises as a perk that will allow one to concentrate on work

More Travel:

The pass starts at $9,990 for a two-guest cabin and is available for four monthlong cruises departing in June, July, August, and September — each departs from ports such as Barcelona, Marseille, and Palma de Mallorca and spends four weeks touring around the Mediterranean.

Longer cruises are becoming more common, here's why

The new pass is essentially a version of an upgraded cruise package with additional perks but is specifically tailored to those who plan on working from the ship as an opportunity to market to them.

"Stay connected to your work with the fastest at-sea internet in the biz when you want and log-off to let the exquisite landscape of the Mediterranean inspire you when you need," reads the promotional material for the pass.

Amid the rise of remote work post-pandemic, cruise lines have been seeing growing interest in longer journeys in which many of the passengers not just vacation in the traditional sense but work from a mobile office.

In 2023, Turkish cruise line operator Miray even started selling cabins on a three-year tour around the world but the endeavor hit the rocks after one of the engineers declared the MV Gemini ship the company planned to use for the journey "unseaworthy" and the cruise ship line dealt with a PR scandal that ultimately sank the project before it could take off.

While three years at sea would have set a record as the longest cruise journey on the market, companies such as Royal Caribbean  (RCL) (both with its namesake brand and its Celebrity Cruises line) have been offering increasingly long cruises that serve as many people’s temporary homes and cross through multiple continents.

As the pandemic turns four, here’s what we need to do for a healthier future

On the fourth anniversary of the pandemic, a public health researcher offers four principles for a healthier future.

Published

Anniversaries are usually festive occasions, marked by celebration and joy. But there’ll be no popping of corks for this one.

March 11 2024 marks four years since the World Health Organization (WHO) declared COVID-19 a pandemic.

Although no longer officially a public health emergency of international concern, the pandemic is still with us, and the virus is still causing serious harm.

Here are three priorities – three Cs – for a healthier future.

Clear guidance

Over the past four years, one of the biggest challenges people faced when trying to follow COVID rules was understanding them.

From a behavioural science perspective, one of the major themes of the last four years has been whether guidance was clear enough or whether people were receiving too many different and confusing messages – something colleagues and I called “alert fatigue”.

With colleagues, I conducted an evidence review of communication during COVID and found that the lack of clarity, as well as a lack of trust in those setting rules, were key barriers to adherence to measures like social distancing.

In future, whether it’s another COVID wave, or another virus or public health emergency, clear communication by trustworthy messengers is going to be key.

Combat complacency

As Maria van Kerkove, COVID technical lead for WHO, puts it there is no acceptable level of death from COVID. COVID complacency is setting in as we have moved out of the emergency phase of the pandemic. But is still much work to be done.

First, we still need to understand this virus better. Four years is not a long time to understand the longer-term effects of COVID. For example, evidence on how the virus affects the brain and cognitive functioning is in its infancy.

The extent, severity and possible treatment of long COVID is another priority that must not be forgotten – not least because it is still causing a lot of long-term sickness and absence.

Culture change

During the pandemic’s first few years, there was a question over how many of our new habits, from elbow bumping (remember that?) to remote working, were here to stay.

Turns out old habits die hard – and in most cases that’s not a bad thing – after all handshaking and hugging can be good for our health.

But there is some pandemic behaviour we could have kept, under certain conditions. I’m pretty sure most people don’t wear masks when they have respiratory symptoms, even though some health authorities, such as the NHS, recommend it.

Masks could still be thought of like umbrellas: we keep one handy for when we need it, for example, when visiting vulnerable people, especially during times when there’s a spike in COVID.

If masks hadn’t been so politicised as a symbol of conformity and oppression so early in the pandemic, then we might arguably have seen people in more countries adopting the behaviour in parts of east Asia, where people continue to wear masks or face coverings when they are sick to avoid spreading it to others.

Although the pandemic led to the growth of remote or hybrid working, presenteeism – going to work when sick – is still a major issue.

Encouraging parents to send children to school when they are unwell is unlikely to help public health, or attendance for that matter. For instance, although one child might recover quickly from a given virus, other children who might catch it from them might be ill for days.

Similarly, a culture of presenteeism that pressures workers to come in when ill is likely to backfire later on, helping infectious disease spread in workplaces.

At the most fundamental level, we need to do more to create a culture of equality. Some groups, especially the most economically deprived, fared much worse than others during the pandemic. Health inequalities have widened as a result. With ongoing pandemic impacts, for example, long COVID rates, also disproportionately affecting those from disadvantaged groups, health inequalities are likely to persist without significant action to address them.

Vaccine inequity is still a problem globally. At a national level, in some wealthier countries like the UK, those from more deprived backgrounds are going to be less able to afford private vaccines.

We may be out of the emergency phase of COVID, but the pandemic is not yet over. As we reflect on the past four years, working to provide clearer public health communication, avoiding COVID complacency and reducing health inequalities are all things that can help prepare for any future waves or, indeed, pandemics.
