The health minister and Tory MP, Nadine Dorries has reportedly tested positive for coronavirus.
The 62 year-old, who has previously worked as a nurse has been told to self-isolate at home.
On Twitter, she thanked people for their good wishes and expressed concern for her mother, who is yet to be tested for the virus.
The MP for Mid Bedfordshire did also confirm her diagnosis in a statement.
I can confirm I have tested positive for coronavirus. Public Health England (PHE) has started detailed contact tracing and the department and my parliamentary office are closely following their advice. I would like to thank PHE and the wonderful NHS staff who have provided me with advice and support.
The news that she has the disease comes after a sixth person in the UK died following the outbreak and further criticism of the government's relaxed approach to the escalating problem.
The government's health secretary Matt Hancock has said that it will "take a national effort to combat the virus" and just a few days ago, Dorries herself praised her colleague who she claimed had a "total grip" on the situation since "day one."
In response to Dorries diagnosis, Hancock said he was "really sorry" but that she had "done the right thing" by self-isolating.
Dorries reportedly showed symptoms last Thursday after she attended an International Women's Day event at Downing Street with Boris Johnson. She had also voted and spoken in the Commons within the past week, meaning that she was more than likely in close contact with other MPs. It has not been confirmed if the prime minister has yet gone under tests for coronavirus.
