This doesn't appear to be the case with monkeypox
In a moment that echoes the hard lessons of recent pandemic history, the World Health Organization raised its highest alarm over monkeypox on Saturday — not because the virus moves through the air as COVID-19 does, but because it has moved through the world with unexpected speed, reaching 16,000 people across 75 countries in a matter of weeks. What was once a disease largely confined to Africa has found new pathways through global travel and intimate contact, prompting a coordinated international response before the window for containment closes. The declaration is less a statement of catastrophe than a call to act while acting still matters.
- A virus that spent decades confined to Africa has erupted across 75 countries in under three months, forcing the WHO to invoke its highest level of global alert.
- Unlike COVID-19, monkeypox spreads through skin-to-skin contact rather than the air — but that narrower transmission route has not stopped it from seeding itself in entirely new regions.
- Sexual health clinics are being thrust onto the front lines of outbreak response despite years of budget cuts that have left them ill-equipped to scale up testing, tracing, and vaccination.
- Five deaths have been recorded, all in Africa, where healthcare access is most limited — a quiet signal that medical infrastructure, not just the virus itself, determines who survives.
- The WHO's emergency declaration is designed to unlock vaccines, funding, and global coordination before monkeypox becomes permanently established outside its historic range.
On Saturday, the World Health Organization declared monkeypox a global health emergency — its most serious designation — after the virus spread from a handful of cases in the United Kingdom in early May to more than 16,000 infections across 75 countries by late July. Five people have died, all in Africa, where the virus has long been endemic. WHO Director-General Tedros Adhanom Ghebreyesus determined that the outbreak's velocity demanded immediate, coordinated global action.
Monkeypox is not a new disease. It spreads through close physical contact with an infected person, or through contaminated clothing and bedding, causing fever, body aches, and distinctive skin lesions that typically resolve within weeks. Outside Africa, the current outbreak has concentrated almost entirely among men who have sex with men. Crucially, the virus does not travel through the air the way COVID-19 does, making it less contagious — but experts warn that does not make it harmless, and there is genuine concern it could become permanently established in regions where it has never before taken hold.
Scientists are still working to understand what changed this year. Increased global travel and climate-driven shifts in animal habitats are both suspected contributors, but neither offers a quick solution. In the meantime, the response depends heavily on sexual health clinics that have faced years of underfunding and are now being asked to lead testing, contact tracing, and vaccination efforts. The primary vaccine, manufactured by Denmark's Bavarian Nordic, is being distributed to high-risk individuals, though supply and logistics remain strained.
The emergency declaration is intended to prevent the slow-motion failure that defined the early COVID-19 response — mobilizing resources and political will before the outbreak outpaces the ability to contain it. Whether governments and pharmaceutical companies will move quickly enough is the question that now hangs over the global public health community.
On Saturday, the World Health Organization made its most serious declaration: monkeypox had become a global health emergency. Tedros Adhanom Ghebreyesus, the WHO's director-general, announced that the virus had crossed a threshold that demanded the world's immediate, coordinated attention. What began as a handful of cases in the United Kingdom in early May had metastasized into something far larger. By late July, more than 16,000 people across 75 countries had been infected. Five had died, all of them in Africa, where the virus had long circulated but rarely ventured beyond.
Monkeypox is not a new pathogen. It was first identified in primates, and it spreads primarily through close physical contact with someone who carries an active infection. The virus causes fever, body aches, and distinctive pus-filled skin lesions that typically resolve within two to four weeks. For decades, it remained largely confined to Africa, where it is endemic. But this year, something shifted. The virus found its way into Europe and then across the globe, moving through networks of close contact in ways that alarmed public health officials.
The current outbreak has a particular geography. Outside of Africa, cases are concentrated almost exclusively among men who have sex with men. The virus spreads through intimate skin-to-skin contact, and also through exposure to contaminated clothing or bedding. This transmission pattern is fundamentally different from COVID-19, which travels through the air via respiratory droplets and proved devastatingly efficient at moving through populations. "COVID is spread by respiratory route and is highly infectious," noted Dr. Martin Hirsch of Massachusetts General Hospital. "This doesn't appear to be the case with monkeypox." The distinction matters. Monkeypox is harder to catch, but it is not benign.
The WHO's emergency declaration was not made lightly. Health officials from multiple countries had pressed the organization to act, citing the velocity of the outbreak and the genuine risk that monkeypox could become established in new regions where it had never taken root before. The declaration serves a specific purpose: it mobilizes resources, coordinates global action, and signals to governments and pharmaceutical companies that vaccines, treatments, and testing capacity must be scaled up urgently. The fatality rate in previous African outbreaks of the strain now spreading globally has hovered around one percent. But in countries with robust healthcare systems, the death rate has been lower so far, suggesting that access to medical care makes a measurable difference.
Yet questions remain unanswered. Scientists are still working to understand what triggered this particular outbreak and whether the virus itself has changed in ways that make it more transmissible or more likely to spread beyond its traditional boundaries. Experts point to two broad forces: increased global travel, which moves viruses across borders faster than ever before, and climate change, which alters the habitats and ranges of the animals that carry zoonotic diseases. These are long-term structural problems without quick fixes.
In the immediate term, the response depends on infrastructure that has been chronically underfunded. Sexual health clinics, which are on the front lines of identifying and treating monkeypox cases, have faced years of budget cuts and neglect. They are now being asked to scale up testing, contact tracing, and vaccination efforts without the resources they need. The WHO has begun distributing vaccines to high-risk individuals and to people who have had recent close contact with infected persons. A Danish pharmaceutical company, Bavarian Nordic, manufactures the primary vaccine being deployed. But production and distribution remain constrained.
For now, the advice is straightforward: avoid close contact with anyone who has an unexplained rash or signs of illness. If you suspect you have monkeypox, isolate yourself and seek medical attention. The emergency declaration is meant to prevent the scenario that unfolded with COVID-19, where a virus that seemed distant and manageable suddenly became impossible to contain. Whether the world's response will be fast enough, and whether the necessary resources will actually materialize, remains to be seen.

COVID is spread by respiratory route and is highly infectious. This doesn't appear to be the case with monkeypox.— Dr. Martin Hirsch, Massachusetts General Hospital
La Conversación del Hearth Otra perspectiva de la historia
Why did the WHO wait until 16,000 cases to declare an emergency? Couldn't they have acted sooner?
The declaration came when officials from multiple countries pushed for it, when the trajectory made clear this wasn't going to stay contained to Africa. Early on, it looked like isolated cases in Europe. By July, it was obvious the virus was establishing itself in new populations.
But it's less contagious than COVID. Why the alarm?
Less contagious doesn't mean safe. The real fear is endemicity—that monkeypox becomes permanently established in countries where it's never been before. Once that happens, you're managing it forever, not containing it.
Who's actually getting sick outside of Africa?
Almost entirely men who have sex with men. The virus spreads through intimate contact, so it follows networks of close physical contact. That's not a judgment; it's epidemiology.
What about the vaccines? Are there enough?
That's the constraint. Bavarian Nordic makes the main vaccine, but production is limited. The emergency declaration is supposed to unlock resources and prioritization, but sexual health clinics have been starved of funding for years. They're being asked to do more with less.
So what happens now?
The declaration creates political pressure and coordination mechanisms. Governments have to act. Pharmaceutical companies have to prioritize production. But whether that translates into actual doses in people's arms, quickly enough to prevent spread—that's the open question.
