Boris Johnson's fiancee Carrie Symonds recovering from coronavirus

Carrie Symonds, fiancee of British Prime Minister Boris Johnson, said on Saturday she was “on the mend” after a week suffering from symptoms of COVID-19.

Symonds, 32, tweeted: “I’ve spent the past week in bed with the main symptoms of Coronavirus,” though she had not been tested.

Symonds, who is pregnant, is not currently staying with Johnson at the prime minister’s Downing Street residence.

She said in a tweet that “being pregnant with Covid-19 is obviously worrying” but she was reassured by the latest medical guidance.

The UK's Royal College of Obstetricians and Gynecologists says babies are unlikely to be exposed to COVID-19 during pregnancy and there is also no data at the moment suggesting an increased risk of miscarriage for pregnant women.

Johnson tested positive for the virus on March 26 and remains quarantined in Downing Street.

For most people, the new coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks.

For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia and death.

The vast majority of people recover.
