A UK junior health minister has tested positive for coronavirus.
Conservative MP Nadine Dorries, who oversees patient safety, is self-isolating at home.
She started feeling unwell on Thursday - the same day she attended an event at Downing Street hosted by Boris Johnson.
Ms Dorries tweeted to say she hopes she's over the worst of the virus and is now more worried about her 84-year-old mother:
Thanks for so many good wishes. It’s been pretty rubbish but I hope I’m over the worst of it now. More worried about my 84yo mum who is staying with me and began with the cough today. She is being tested tomorrow. Keep safe and keep washing those hands, everyone.

Elsewhere in the UK, a Premier League match has been called off tonight due to Covid-19.
Some of Arsenal's players met Evangelos Marinakis - the owner of Greek club Olympiakos - 13 days ago, but he has since tested positive for coronavirus.
As a result, tonight's game against Manchester City has been postponed as a precaution.
The players who met Mr Marinakis are now self-isolating.
In a statement, Arsenal said: "The medical advice we have received puts the risk of [the players] developing Covid-19 at extremely low.
"However, we are strictly following the Government guidelines which recommend that anyone coming into close contact with someone with the virus should self-isolate at home for 14 days from the last time they had contact."
Both Arsenal and Manchester City have wished Mr Marinakis a swift recovery.
Last night, ten new cases of coronavirus in the Republic of Ireland were confirmed by health officials.
It brings the total on the island of Ireland to 50, after Northern Ireland’s Department of Health earlier confirmed the total there had risen to 16 cases.
The Department of Health's Chief Medical Officer Dr Tony Holohan said five of the new cases in the Republic are associated with travel, while the other five had contact with previously confirmed cases.
The figures include two healthcare workers - one man and one woman.
He said 1,784 suspected cases have now been tested in Ireland, with 98% testing negative.
Last night, EU leaders agreed funding for research to find a vaccine and to ensure enough medical equipment and supplies during the outbreak.
The bloc's health ministers will hold daily talks, while airlines will be protected from losing landing slots where flights are suspended.
Meanwhile, coronavirus cases continue to soar across Italy, the European country worst impacted by the outbreak.
The entire country is now into the second day of a lockdown, with severe travel restrictions and a ban on public gatherings in effect.
Thousands of flights to and from Italy have been cancelled, while Austria is refusing to let travellers cross the border without a medical certificate.
More than 10,000 cases have been confirmed in Italy.
The death toll yesterday rose to 631 people - an increase of 168 people in the space of 24 hours.
