Harry Potter actress Jessie Cave has revealed her newborn son has tested positive for COVID-19.
Cave, who is best known for playing Lavender Brown in the Harry Potter series, shared the worrying news on social media.
The 33-year-old posted a picture of her son in a hospital bed as she watched British Prime Minister Boris Johnson's lockdown announcement.
"I watched the news about lockdown from an isolated room in the hospital. Poor baby is COVID positive," she wrote.
"He's okay and doing well but they are being vigilant and cautious thankfully. This strain is super powerful and contagious so I do hope that people take extra care in the coming weeks."
Johnson announced a new nationwide lockdown on Monday as a mutated strain of COVID-19 spreads throughout the country.
To slow the spread, Johnson announced everyone in England must stay home except for permitted reasons, with all schools and universities closed. The lockdown is expected to last until mid-February.
The difference between now and back in March - when the UK first went into a national lockdown - is that Britain is now rolling out vaccinations, Johnson says.
He believes the country is entering the "last phase of the struggle" despite the weeks ahead likely to be the hardest yet.
"Thanks to the miracle of science, not only is the end in sight but we know exactly how we are going to get there."
