Expert opinion

Nelson Mandela famously said “the youth of today are the leaders of tomorrow”. This is perhaps no more true than the role of young people in advocating for immediate action on climate change.

March 2022 marks two years since the World Health Organization (WHO) declared the rapid and wide spread of COVID-19 to be a pandemic. It was – sadly - clear that the world wasn’t ready. Two years and more than six million deaths later, and following scores of articles about how countries could have done better, what have we learnt? Are we ready for the next threat?
Those are the words of Olga, a 71-year-old woman who lives just five kilometres from the “contact line”, in Luhansk province, in the government-controlled area (GCA) of Eastern Ukraine, speaking a week before Russia escalated its invasion of Ukraine. Her son, granddaughter and two great grandchildren live on the other side of the stretch of land, in the non-government-controlled area (NGCA). They are separated by ongoing fighting and various checkpoints, making visits difficult and dangerous. Olga lives alone and has difficulty walking because of pain in her legs and joints.

This caused widespread concern and a petition to overturn the decision has received over 1.2 million signatures to date.  
Malaria infection exerts a tremendous impact on the body, which can have long-term health repercussions, ranging from accrued susceptibility to bacterial infection to cognitive impairment. While some of these nefarious effects are known for the most severe forms of the disease, mounting evidence suggest that this is merely the tip of the iceberg.
Once again COVID is resurging across Europe. But not all countries are in the same position. Why? It’s an easy question to answer, yet confusion reigns in the press, on social media, and even among some scientists and epidemiological modellers. The answer is a basic epidemiological principle - population immunity - a concept that any young epidemiologist learns in early career development, as did I during my first month at the Centers for Disease Control and Prevention (CDC) back in 1976.
