Long COVID could cost OECD countries €116 billion a year over the next decade

The long-term illness impacting some people who suffered a COVID-19 infection, known as long COVID, could cost OECD (Organisation for Economic Co-operation and Development) countries a total of $135 billion (almost €116 billion) per year over the next decade.
