Coronavirus Covid-19 has claimed the lives of more than 82,000 people around the world. There have been more than 1,440,000 confirmed cases - with 308,000 people recovering.
And while it is a race against time to find out more about this new, highly-infectious disease, what is clear is that Covid-19 can affect people in dramatically different ways.
From Prince Charles, 71, who displayed mild symptoms and was "otherwise in good health" to actor Idris Elba, 47, who tested positive, but had no symptoms.
But this invisible enemy has also killed more than 6,000 people in the UK, including a five-year-old child, and left many others fighting for their lives or in intensive care, including our Prime Minister Boris Johnson, 55.
