The resources are scarce for the scale of the problem
Em meados de setembro de 2020, Portugal deparou-se com um sinal de alerta que os especialistas esperavam, mas não tão cedo: 770 novos casos de COVID-19 num único dia, o valor mais alto desde abril, quando o país ainda vivia sob estado de emergência. A pandemia, como tantas crises humanas, não respeitou o calendário que lhe foi atribuído — chegou antes, mais forte, e encontrou um sistema de saúde pública ainda a tentar apanhar o passo. O momento revelou não apenas a fragilidade dos recursos, mas a distância sempre presente entre o que se antecipa e o que, afinal, acontece.
- Portugal registou 770 novos casos de COVID-19 a 17 de setembro, o número diário mais elevado desde abril, forçando o primeiro-ministro António Costa a convocar uma reunião de crise de emergência.
- Os especialistas de saúde pública admitiram estar preocupados: o aumento era esperado para o outono, mas chegou semanas antes do previsto, apanhando o sistema de vigilância desprevenido.
- Os dados do dia não refletiam ainda o impacto real do regresso às aulas — as infeções contraídas nas escolas só apareceriam nas estatísticas duas semanas depois, criando um perigoso ponto cego.
- A capacidade de resposta das unidades de saúde pública revelou-se insuficiente face à escala do problema, com recursos escassos a dificultar a vigilância epidemiológica em tempo útil.
- A experiência dos subúrbios de Lisboa, onde equipas multidisciplinares travaram surtos anteriores, surge agora como modelo urgente a replicar em todo o país, especialmente nas escolas.
A 17 de setembro de 2020, Portugal registou 770 novas infeções por coronavírus num único dia — o valor mais alto desde 10 de abril, quando o país ainda estava em estado de emergência. A gravidade do número foi imediata: o primeiro-ministro António Costa convocou uma reunião de crise de emergência para o dia seguinte, em São Bento.
Ricardo Mexia, presidente da Associação Nacional de Médicos de Saúde Pública, reconheceu a inquietação que atravessava o sistema. O aumento de casos era esperado com o fim das férias, o regresso às aulas e a chegada dos meses frios. Mas a antecipação do surto apanhou os especialistas de surpresa. "Este aumento acabou por ser mais cedo do que o esperado", admitiu.
O que tornava o momento ainda mais perturbador era o que os números ainda não mostravam. Os 770 casos refletiam infeções de dias anteriores. O verdadeiro impacto do regresso às escolas só seria visível nas estatísticas duas semanas depois — e o mesmo atraso aplicava-se às hospitalizações, internamentos em cuidados intensivos e óbitos.
Mexia identificou a falta de capacidade como o problema central. As unidades de saúde pública não tinham recursos suficientes para fazer vigilância epidemiológica em tempo real, e à medida que os casos aumentavam, o fosso entre o necessário e o possível alargava-se. Como exemplo de resposta eficaz, apontou o que acontecera nos subúrbios de Lisboa, onde equipas multidisciplinares — epidemiologistas, enfermeiros, assistentes sociais — tinham conseguido conter a propagação. Com as escolas abertas em todo o país, esse modelo seria agora mais essencial do que nunca.
Quanto à questão de saber se Portugal entrava numa segunda vaga, Mexia preferiu não se deter na terminologia. O que importava era a trajetória, a capacidade de resposta e a velocidade de adaptação. E os números de quinta-feira tinham deixado uma coisa clara: essa adaptação não podia esperar.
On Thursday, September 17th, Portugal recorded 770 new coronavirus infections in a single day—the highest daily count since April 10th, when the country was still under a state of emergency. The number was jarring enough that Prime Minister António Costa immediately convened an emergency crisis meeting for the following day at his office in São Bento.
The surge had arrived ahead of schedule. Ricardo Mexia, president of the National Association of Public Health Physicians, acknowledged the anxiety rippling through the health system. He and his colleagues had anticipated a rise in cases as summer holidays ended, schools reopened, and the autumn and winter months brought their typical circulation of respiratory viruses. But the timing caught them off guard. "We are concerned about the increase in cases," Mexia said. "We knew an increase was likely, given the return from vacation, the resumption of school activities, and the typical circulation of respiratory viruses in autumn and winter. But this increase turned out to be earlier than expected."
What made the moment particularly unsettling was what the numbers did not yet reflect. The 770 cases recorded that Thursday represented infections contracted days earlier. The real impact of students returning to classrooms would not show up in the data for another two weeks. The same lag applied to hospitalizations, intensive care admissions, and deaths—all of which trail behind the initial spike in confirmed cases by a matter of days or weeks. Mexia, a public health specialist at the National Institute of Health Dr. Ricardo Jorge, underscored this temporal gap as a critical blind spot in the response.
The core problem, he argued, was capacity. Public health units across the country lacked the resources to conduct epidemiological surveillance in real time, to track cases and their contacts with the speed the moment demanded. As case numbers climbed, the gap between what needed to be done and what could actually be done widened. "It is fundamental to strengthen our response capacity," Mexia said. "Specifically, in Public Health Units, it is essential to have the ability to conduct epidemiological surveillance in a timely manner. This has not been happening because the resources are scarce relative to the scale of the problem, and as cases increase, it becomes increasingly difficult."
He pointed to what had unfolded months earlier in the suburbs of Lisbon as a cautionary example—a moment when the shortage of personnel and equipment to contain spread had been painfully visible. The solution implemented there, he noted, was the deployment of multidisciplinary teams, combining epidemiologists, nurses, social workers, and other specialists to work in concert. It had worked. Now, with schools reopening across the country, such teams would be more necessary than ever. "It's a good example," Mexia said. "And now, with schools, they will be even more essential."
When asked whether Portugal was entering a second wave of the pandemic, Mexia demurred. The question, he suggested, was not particularly relevant from a technical standpoint. What mattered was the trajectory, the capacity to respond, and the speed at which the health system could adapt. The numbers on Thursday had made one thing clear: adaptation could not wait.

The Hearth Conversation Another angle on the story
When Mexia says the surge came earlier than expected, what exactly was he expecting?
He and other officials had modeled a rise in cases tied to specific events—the end of summer holidays, schools reopening, the seasonal shift into autumn. They anticipated it would happen, but they thought they had more time before it became visible in the data.
Why does the timing matter so much if the cases were going to happen anyway?
Because preparation takes time. If you know something is coming in October, you can staff up in September. If it arrives in mid-September, you're caught short. And in a pandemic, being caught short means the system fractures.
He mentions the lag between cases and hospitalizations. How long are we talking?
Typically a week or two. Someone gets infected, takes a few days to show symptoms, a few more days before they're sick enough to need a hospital bed. By the time you see the real burden, the wave is already here.
So on Thursday, when they counted 770 cases, the actual crisis was still invisible?
Exactly. Those 770 people were already infected days before. The people who would need ICU beds hadn't arrived yet. The deaths hadn't happened yet. The system was looking at a rearview mirror.
What does he mean by multidisciplinary teams?
Not just doctors. Epidemiologists to trace contacts, nurses to do follow-ups, social workers to help people isolate safely, sometimes translators. The Lisbon suburbs showed that you can't fight a surge with epidemiologists alone.
And the question about a second wave—why does he dismiss it?
Because the label doesn't change what you have to do. Whether it's a second wave or a continuation of the first, the work is the same: test, trace, isolate, support. The name is less important than the response.
