The outbreak is serious, but the emergency declaration would change little
En el verano de 2022, la Organización Mundial de la Salud se reunió por segunda vez para deliberar si el brote de viruela del mono había alcanzado la categoría de emergencia sanitaria global. En cuatro semanas, los casos se habían cuadruplicado hasta 16.000 en casi 80 países, con España como epicentro mundial. La humanidad se encontraba ante una pregunta que trasciende los números: ¿cuándo una amenaza emergente deja de ser un problema vigilado para convertirse en una crisis que exige la máxima respuesta colectiva?
- Los casos globales se cuadruplicaron en un mes —de 4.000 a 16.000— y el ritmo diario de contagios casi se triplicó, forzando a la OMS a reconsiderar su decisión de junio de no declarar emergencia.
- España, con 3.400 casos confirmados, se convirtió en el país más afectado del mundo desarrollado, mientras su campaña de vacunación avanzaba a paso lento por la escasez de dosis.
- El virus comenzó a traspasar sus redes iniciales de transmisión: un bebé de siete meses en Madrid se infectó, al menos 30 menores resultaron afectados, y el 7% de los casos ya se registraban fuera de entornos de alto riesgo sexual.
- Los expertos debatían si se cumplían los ocho criterios de la OMS para declarar la emergencia, con voces autorizadas argumentando que hacerlo no cambiaría sustancialmente las estrategias sanitarias ya en marcha.
- La decisión del comité, esperada en días, definiría si el mundo trataría la viruela del mono como un umbral histórico cruzado o como un brote grave pero contenible dentro de los mecanismos ordinarios de vigilancia.
A finales de julio de 2022, la OMS convocó su segundo comité de emergencia para determinar si la viruela del mono había cruzado el umbral de crisis sanitaria global. Las cifras habían cambiado drásticamente en un mes: los casos se cuadruplicaron de 4.000 a 16.000 en casi 80 países. España se había convertido en el epicentro del brote en el mundo desarrollado, con cerca de 3.400 infecciones confirmadas.
Un mes antes, el 23 de junio, el mismo comité había concluido que era prematuro declarar una emergencia de salud pública de importancia internacional —la máxima alerta de la organización, compartida entonces solo con la COVID-19 y la polio—. En aquel momento, la mayoría de los casos eran leves y la transmisión se concentraba casi exclusivamente en redes de hombres que tienen sexo con hombres. Pero el panorama había cambiado: los contagios diarios pasaron de 223 a 647, y el número de países afectados casi se duplicó.
La respuesta española ilustraba las tensiones del brote. El país había iniciado la vacunación de personas en riesgo, pero con solo 5.000 dosis disponibles mientras esperaba más a través de un proceso de compra europeo de 160.000 unidades. El cuadro clínico seguía siendo mayoritariamente leve —52 hospitalizaciones entre mayo y mediados de julio, principalmente por el intenso dolor de las lesiones—, pero el virus comenzaba a rebasar sus fronteras iniciales.
Entre los más de 2.600 pacientes registrados, once tenían menos de veinte años, y un bebé de siete meses en Madrid había contraído el virus, generando alarma sobre poblaciones vulnerables. Aunque no se habían registrado muertes, al menos el 7% de los casos con información disponible se habían producido fuera de entornos sexuales de alto riesgo.
Los expertos consultados se mostraban escépticos ante la declaración de emergencia. Un virólogo de la Universidad de Surrey consideraba que los ocho criterios de la OMS no se habían cumplido suficientemente, mientras que un exfuncionario de la organización señalaba que declararla no cambiaría fundamentalmente las estrategias que los países ya debían estar aplicando. El análisis genético del virus mostraba unas cincuenta mutaciones desde 2018 —inusualmente alto para un virus de ADN—, pero sin evidencia de mayor transmisibilidad o gravedad. La decisión del comité, esperada en días, definiría cómo el mundo nombraría —y enfrentaría— lo que tenía delante.
In late July 2022, the World Health Organization convened its second emergency committee to decide whether monkeypox had crossed the threshold into a global health crisis. The numbers had moved sharply in four weeks: cases had quadrupled from roughly 4,000 to 16,000, spreading across nearly 80 countries and territories. Spain had become the epicenter of the outbreak in the developed world, with close to 3,400 confirmed infections—more than any other nation.
Just a month earlier, on June 23, the same WHO committee had concluded it was too soon to declare a public health emergency of international concern, the organization's highest alert level. At that time, the reasoning seemed sound. The vast majority of cases were mild. The virus was spreading almost entirely within networks of men who have sex with men, particularly in settings involving multiple partners and close physical contact. The growth, while steady, was not yet exponential. Only three diseases held that emergency designation: COVID-19, polio, and now potentially monkeypox.
But the landscape had shifted dramatically. In the four weeks between meetings, the daily case count had nearly tripled, from about 223 reported cases per day to 647. The number of affected countries had nearly doubled. The WHO's own framework, established after the first meeting, had identified eight specific warning signs that would justify an emergency declaration. The question now was whether enough of them had materialized.
Spain's experience illustrated the outbreak's trajectory. The country had begun vaccinating people at risk—men with recent sexual exposures or those in high-risk settings—but the campaign was constrained by scarcity. Spain had secured 5,000 vaccine doses and was waiting for more through a European Union procurement effort that had committed to 160,000 doses total. The rollout was grinding forward slowly, even as cases climbed by roughly 100 per day.
The clinical picture remained largely reassuring. Santiago Moreno, who headed infectious diseases at Madrid's Ramón y Cajal Hospital, described patients with manageable infections that rarely required specialized treatment. The main complaint was intense pain from the rash, particularly in sensitive areas. Across Spain, 52 people had been hospitalized between May and mid-July—about 3.9 percent of the 1,317 cases tracked by the Carlos III Health Institute. In other European countries, the hospitalization rate was higher at around 8 percent, but nearly all admissions were for pain control rather than life-threatening illness.
Yet the virus was beginning to breach the boundaries of its initial transmission networks. Among the 2,622 patients tracked by the Carlos III Institute as of July 19, twenty-five were women and eleven were under twenty years old. Most striking was a seven-month-old infant in Madrid who had contracted the virus—a case that raised alarms about vulnerable populations. At least thirty children across the outbreak had been infected, though no deaths had occurred. Of the cases where exposure information was available, about 7 percent had occurred outside high-risk sexual settings, including some traced to recreational activities and family contact.
Experts consulted by the publication remained skeptical that the emergency threshold had been crossed. Carlos Maluquer de Motes, a virologist at the University of Surrey, argued that despite rising case numbers, the WHO's eight criteria had not been sufficiently met. Daniel López Acuña, a former WHO crisis response official, made a broader point: the outbreak was a serious public health problem deserving close attention and coordinated measures, but declaring an international emergency would not fundamentally change the strategies countries should already be pursuing. Other diseases with greater transmission potential and higher case burdens had never received such a designation. The genetic analysis of the virus showed it had accumulated roughly fifty mutations since 2018, an unusually high number for a DNA virus, yet no evidence suggested these changes had increased its transmissibility or severity. If it was spreading faster now, it seemed to be because it had found a population and social context where transmission was simply easier.
The committee's decision, expected within days, would signal whether the world's health authorities viewed monkeypox as a threshold event or a manageable outbreak requiring vigilance but not the machinery of maximum alert.

Why did the WHO wait a month before reconvening? Didn't they see this coming?
They had a framework. In June, the committee set eight specific warning signs to watch for. They were essentially saying: we'll reconvene if these things happen. The cases did quadruple, so they reconvened. But having a framework and meeting the threshold are different things.
So the experts still don't think it's an emergency?
Most of the ones quoted don't. The cases are rising, yes, but they're still mild. It's still mostly contained to specific networks. And they point out that other diseases with worse outcomes have never gotten emergency status. It's not that monkeypox isn't serious—it's that the emergency declaration is a very specific tool.
What about the children? A seven-month-old?
That's the thing that worries people most. The virus hasn't killed anyone yet, and hospitalizations are mostly for pain management. But the literature from Africa shows that children and pregnant women and immunocompromised people can get very sick. So far it hasn't happened at scale, but that's what everyone's watching.
Why is Spain so badly hit?
It's not clear from the reporting. But the outbreak seems to have found a particular social context there—networks of men with multiple partners, frequent contact. Once it gets into a network like that, it spreads fast. Spain's also reporting cases more thoroughly than some countries.
The vaccines—why so few doses?
Supply. The vaccine wasn't designed for this. Europe ordered 160,000 doses total, but that's for a continent of hundreds of millions. Spain got 5,000. It's a rationing problem, not a refusal problem.
What happens if they don't declare an emergency?
Probably not much changes on the ground. Countries are already vaccinating, already tracking cases. The emergency declaration is more symbolic—it signals to the world that this is a priority. But if experts think the tools already available are sufficient, the symbol might not matter.
