Expert opinion

As the world continues to face myriad health challenges, including the ongoing COVID-19 pandemic, it is significant that for the first time the World Health Organization (WHO) has chosen to focus this year’s World Health Day on the theme “Our Planet, Our Health”.   Although the health impacts of climate change are increasingly being recognised, health has generally been peripheral to climate change policies and negotiations. As we approach COP27 later this year, WHO’s campaign signals it is time to change that.

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.

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.

The unprovoked and unjustified Russian invasion of Ukraine on 24 February 2022 is already having terrible consequences for health. As we write, only seven days since Russian troops crossed the border, substantial numbers on both sides have died, many due to Russian attacks on civilian targets in violation of international law.

Cervical screening was a hot topic following the announcement that from 1st January 2022 the routine screening interval for people with a cervix aged 25 to 49 in Wales was extended from three to five years. 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.
