More younger people are falling severely ill with coronavirus, the World Health Organisation (WHO) has said, as the number of deaths surpasses 50,000 globally.
The international health body said individuals in their 30s, 40s and 50s were being admitted to intensive care with the disease and dying, despite having no underlying health issues.
However, experts said that the majority of people who experience severe illness still tend to be older and with other health problems.
Dr Mike Ryan, executive director of WHO's emergencies programme, said at a press conference in Geneva on Friday that one in six Covid-19 deaths in Korea had been people under the age of 60.
