Viral Swing: What happens if Donald Trump becomes seriously ill? The line of succession explained

Just 32 days out from the US presidential election, Donald Trump has been taken to hospital with Covid-19 and will be be monitored there "for a few days", the White House has said. At 74, Mr Trump is in the age category deemed most vulnerable to the coronavirus, with around 80 per cent of Covid-19 deaths in the US occurring among those aged 65 and older. Mr Trump has also been reported to have high cholesterol, and at 17st 6lb (110.7kg), is considered obese for his height, which may also make him more vulnerable to the deadly virus. Mr Trump's doctor, Sean Conley, has said the president and his wife Melania Trump are both "well at this time" and receiving treatment. Mr Trump, who has displayed symptoms, is being treated with a Regeneron polyclonal antibody cocktail. He is also taking vitamin C and zinc, melatonin and a daily aspirin, his doctor said. Mr Trump said in a video from his hospital room on Saturday that he felt "much better" and hoped to be "back soon". Dr Conley also suggested that Mr Trump intends to continue "carrying out his duties" while recovering, but as Mr Trump is taken to hospital – and is expected to quarantine for at least the next two weeks – there are some duties the Commander-in-Chief may be unable to perform. In that instance it is likely that many of his duties will be handed over to Mike Pence, the US vice president.
