El antivirus más potente contra la COVID-19: nuestro sistema inmune

Más de 200.000 personas fallecidas, casi la mitad de la población mundial confinada, consecuencias sociales y económicas nunca imaginadas… Y todo ello es causado por un microorganismo, el SARS-CoV-2, que solo mide 120 nanómetros (o sea, 0,00000012 metros). Está claro que, en inmunología, no hay rival pequeño: a pesar de su tamaño, el coronavirus es capaz de poner en jaque nuestro sistema inmune (y nuestro mundo).

Aunque los datos disponibles son aún limitados, conocer los mecanismos implicados en la respuesta inmune frente a un virus como este puede ser crucial para entender la enfermedad y hacerle frente con contundencia.

Se todos usarem máscara, nível de proteção vai além dos 85%

Miguel Guimarães alerta ainda que o regresso à vida normal tem que ser feito de forma "muito cautelosa" sob pena de termos uma "recaída" na infeção por Covid-19 no país.

Defensor desde cedo do uso generalizado de máscaras, Miguel Guimarães referiu, em declarações à SIC Notícias esta sexta-feira, que a “curva [epidemiológica] está aparentemente estável”, não se tendo registado uma “subida exponencial como aconteceu em Espanha”. O que “dá mais capacidade ao Serviço Nacional de Saúde (SNS) de poder responder adequadamente às necessidades que  vão existindo”, admitiu.

Todavia, com a abertura para o regresso à vida “normal”, esse cenário que á agora favorável pode alterar-se, avisou. “Esta abertura da possibilidade de as pessoas terem uma vida mais normal tem que ser feita de forma muito cautelosa”, disse, sugerindo que Portugal siga o exemplo da Alemanha.

How to shift your mindset and choose your future

When it comes to big life problems, we often stand at a crossroads: either believe we’re powerless against great change, or we rise to meet the challenge. In an urgent call to action, political strategist Tom Rivett-Carnac makes the case for adopting a mindset of “stubborn optimism” to confront climate change — or whatever crisis may come our way — and sustain the action needed to build a regenerative future. As he puts it: “Stubborn optimism can fill our lives with meaning and purpose.”

00:13 – I never thought that I would be giving my TED Talk somewhere like this. But, like half of humanity, I’ve spent the last four weeks under lockdown due to the global pandemic created by COVID-19. I am extremely fortunate that during this time I’ve been able to come here to these woods near my home in southern England. These woods have always inspired me, and as humanity now tries to think about how we can find the inspiration to retake control of our actions so that terrible things don’t come down the road without us taking action to avert them, I thought this is a good place for us to talk. And I’d like to begin that story six years ago, when I had first joined the United Nations.

Is COVID-19 Leading to a Mental Illness Pandemic?

We are in the midst of an epidemic and possibly pandemic of anxiety and distress. The worry that folks have about themselves, families, finances, and work is overwhelming for millions.

I speak with people who report periods of racing thoughts jumping back in time and thinking of roads not taken. They also talk about their thoughts jumping forward with life plans of what they’ll do to change their lives in the future – if they survive COVID-19.

Consider what this uncertainty is doing to people who have an underlying emotional problem that is well-controlled with care (and even without care). Those people are suffering even more. Meanwhile, people with obsessive-compulsive disorder that had been under control appear to have worsened with the added stress.
