A British teenager fell into a 10-month coma before the pandemic. Now he's waking up in a new world

Flavill's accident came three weeks before the UK went into lockdown.

London (CNN)Joseph Flavill slipped out of one world and woke up in another.

On March 1, 2020, when the 19-year-old was struck by a car in Staffordshire, central England, the United Kingdom had recorded just 23 cases of a concerning new virus. The vast majority of Covid-19 infections were still confined to China, and the United States had confirmed just one death.
Sporting events, bars and restaurants teemed with life. And in Flavill's home country that day, newspaper front pages were leading not with the spreading disease, but on Prime Minister Boris Johnson's announcement that he and his fiancée were expecting a child.

    The family's ordeal began just days before the rapid onslaught of cancellations, fatalities and lockdowns.
    Flavill, a cricket and hockey fan, was preparing to visit Buckingham Palace in May to collect the Duke of Edinburgh youth achievement award. But a collision with a car left him with a traumatic brain injury to the back of his head, and he was rushed to a hospital in Leicester, central England.

    Three weeks later, Britain was in lockdown -- meaning only his mother, Sharon Flavill, was permitted to visit him in hospital, at a distance, dressed head-to-toe in protective equipment. "Life was suspended, and then lockdown happened," said Yarbo.
    His mother is still waiting until it's safe to touch her son, who is now recovering at a care home.
    The pandemic has drastically affected Flavill's hospital care, but it is unclear whether he has grasped his family's explanations as to why.
