Boris Johnson's pregnant fiance says she is 'on the mend' from COVID-19

British Prime Minister Boris Johnson's pregnant fiance, Carrie Symonds on Sunday revealed that she was bedridden after developing symptoms of coronavirus but is now on the mend and feeling stronger.

The 32-year-old conservationist had been self-isolating separately from Johnson with the couple's dog Dilyn. Her social media post on her own symptoms subsiding came as Johnson, 55, continues to self-isolate at Downing Street after testing positive for coronavirus last week.

"I've spent the past week in bed with the main symptoms of coronavirus. I haven't needed to be tested and, after seven days of rest, I feel stronger and I'm on the mend," Symonds posted on Twitter.

In an accompanying post, Johnson's partner, who is around six months pregnant and expecting the couple's baby in the coming months, added a link to guidance from the UK's Royal College of Obstetricians and Gynaecologists for pregnant women during the pandemic.

"Being pregnant with COVID-19 is obviously worrying. To other pregnant women, please do read and follow the most up to date guidance which I found to be very reassuring," she said.

In an earlier post on Instagram, Symonds believed to be at her flat in Camberwell, south London is seen lying in bed with Dilyn with the caption: "Self-isolating isn't so bad with this one."
