The risk of monkeypox is moderate globally, except in Europe where it is high
On July 23, 2022, the World Health Organization placed monkeypox among the gravest categories of global threat, as its director-general invoked the agency's highest alarm — a Public Health Emergency of International Concern — after weeks of institutional hesitation and a deadlocked expert committee. Nearly 16,000 people across 72 countries had already been infected, and the outbreak's rapid migration beyond its traditional home in West and Central Africa signaled that the virus had found new footholds in a world unprepared to receive it. The declaration was both a warning and an admission: that caution, however reasonable, carries its own consequences when a disease moves faster than consensus.
- A virus long confined to West and Central Africa had, since May, quietly crossed borders into 72 countries, infecting nearly 16,000 people before the world's foremost health body formally acknowledged the scale of the threat.
- WHO's own expert committee deadlocked twice — unable to agree that the outbreak had crossed the threshold for the highest alert — leaving Director-General Tedros to make a rare unilateral call after more than six hours of inconclusive debate.
- Public health voices grew louder in the days before the declaration, with experts warning that case numbers were already rising exponentially and would 'dramatically increase in the coming weeks and months' without urgent intervention.
- Europe, where the outbreak had accelerated most sharply, was designated high-risk — a distinction that underscored how far monkeypox had traveled from its endemic origins and how unprepared many health systems were to contain it.
- With the PHEIC now declared, the machinery of international health response is expected to shift into higher gear — but the central question remains whether coordinated global action can outpace a curve already bending steeply upward.
On Saturday, July 23, 2022, WHO Director-General Tedros Adhanom Ghebreyesus stood before a Geneva press conference and declared monkeypox a Public Health Emergency of International Concern — the organization's highest alert level. By that point, nearly 16,000 people across 72 countries had been infected, according to U.S. CDC tallies.
The road to the declaration had been anything but smooth. A WHO expert committee convened in late June had failed to reach consensus, with a majority advising against the designation. As cases continued climbing through early July, Tedros called the committee back for a second session that stretched past six hours — and still produced no agreement. That left the decision to Tedros alone, a rare exercise of the director-general's authority to act without committee consensus.
In framing the announcement, Tedros drew a careful distinction: globally, the risk was moderate, but in Europe — where the outbreak had accelerated most sharply — it was high. The significance lay in geography. Monkeypox had long been endemic to West and Central Africa, circulating in animal populations and occasionally crossing into humans. What alarmed health officials was the surge that began in early May in countries with no prior experience managing the disease, suggesting the virus had found new transmission pathways.
The pressure to act had been building publicly. Lawrence Gostin of the WHO Collaborating Centre on National and Global Health Law warned on social media that cases had risen exponentially since the committee's first meeting, urging Tedros to sound the alarm before numbers climbed further. That exponential trajectory was already visible in the data — not a projection, but a present reality.
By declaring the PHEIC, Tedros implicitly acknowledged that institutional caution had come at a cost. The declaration unlocks international coordination mechanisms, obliging countries to share information and prepare for the surge epidemiologists were already forecasting. Whether that response could move quickly enough to bend the curve remained the urgent, open question.
On Saturday, July 23, 2022, the World Health Organization made a decision that had been hanging in the balance for weeks: monkeypox was now a global health emergency. Tedros Adhanom Ghebreyesus, the WHO's director-general, announced the declaration at a Geneva press conference, invoking the organization's highest alarm level—a designation called a Public Health Emergency of International Concern, or PHEIC. Nearly 16,000 people across 72 countries had been infected by that point, according to tallies from the U.S. Centers for Disease Control and Prevention.
The path to this declaration had been uncertain. An expert committee convened by the WHO on June 23 could not agree that monkeypox had crossed the threshold for a PHEIC. A majority of the committee's members advised against it. But as cases climbed through early July, Tedros called the committee back for a second meeting on Thursday. The discussion stretched past six hours. Still, the experts could not reach consensus. That left the decision to Tedros alone—a rare moment when the director-general must act without the committee's agreement.
When Tedros made his announcement, he framed the risk carefully. Globally, he said, the threat level was moderate. But in Europe, where the outbreak had accelerated most dramatically, the risk was high. This distinction mattered because monkeypox had long been endemic to West and Central Africa, where it circulated in animal populations and occasionally spilled into humans. What was new—and alarming—was the surge that began in early May outside those regions. The virus had found new pathways of transmission in countries with no prior experience managing it.
The timing of the declaration reflected growing pressure from public health experts who saw the trajectory of the outbreak and feared the world was not moving fast enough. Lawrence Gostin, director of the WHO Collaborating Centre on National and Global Health Law, posted on Twitter late Friday that cases had risen exponentially since the committee's first meeting just weeks earlier. He called on Tedros to sound the alarm, warning that case numbers would "dramatically rise in the coming weeks and months." The exponential growth was not hypothetical—it was already visible in the data.
Tedros's decision to declare a PHEIC was, in effect, an acknowledgment that the expert consensus had been wrong, or at least incomplete. The committee had been cautious, perhaps appropriately so given the uncertainty surrounding a novel outbreak. But caution had a cost: it delayed the global mobilization that a PHEIC declaration triggers. Once Tedros made the call, the machinery of international health response could shift into higher gear. Countries would be expected to coordinate, share information, and prepare for the surge that epidemiologists were already predicting. The question now was whether that machinery could move fast enough to slow the spread.

I have decided that the global monkeypox outbreak represents a public health emergency of the international concern— WHO Director-General Tedros Adhanom Ghebreyesus
Since the last monkeypox emergency committee just weeks ago, we've seen an exponential rise in cases. It's inevitable that cases will dramatically rise in the coming weeks and months.— Lawrence Gostin, director of the WHO Collaborating Centre on National and Global Health Law

Why did the WHO's expert committee hesitate the first time around?
They didn't have enough clarity on whether monkeypox truly met the threshold for the highest alert. It was spreading, yes, but the committee wanted to see more data, more certainty. Caution is built into how these committees work.
But then Tedros overruled them?
Not exactly overruled. He had the authority to decide when the committee couldn't agree. And by the second meeting, the numbers had shifted enough that he felt he had to act.
What made Europe different from Africa in his assessment?
Africa had lived with monkeypox for years—it was endemic, manageable in some sense. Europe had no infrastructure for it, no experience. The virus was moving faster there, finding new transmission routes. That's what made the European risk "high" while the global risk stayed "moderate."
Was Tedros responding to pressure from people like Gostin?
Partly, maybe. But Gostin was reading the same exponential curve Tedros was seeing. The pressure came from the data itself. Once you see cases doubling every few weeks, waiting becomes harder to justify.
What happens now that it's officially an emergency?
Countries have to treat it as such. Resources flow differently. Coordination becomes mandatory, not optional. But the real test is whether that changes the trajectory of the outbreak.
