Health minister and Conservative MP Nadine Dorries says she has been diagnosed with coronavirus.
Ms Dorries, the first MP to test positive, said she had taken all the advised precautions after finding out and had been self-isolating at home.
It comes as a sixth person died from the virus in the UK, which has a total of 382 cases.
The latest person to die was a man in his early 80s who had underlying health conditions.
Meanwhile, GPs are warning that routine appointments at surgeries may have to stop as the number of coronavirus cases rises.
Ms Dorries, who has been an MP since 2005, said in a statement: “I can confirm I have tested positive for coronavirus.”
She added: “Public Health England has started detailed contact tracing and the department and my parliamentary office are closely following their advice.”
Health Secretary Matt Hancock tweeted that she had “done the right thing” by self-isolating at home and wished “her well as she recovers”.
He added: “I understand why people are worried about this disease. We will do all we can to keep people safe, based on the best possible science.”
Earlier, England’s deputy chief medical officer defended the decision to delay closing schools and introducing other stringent measures, saying experts were assessing new cases on an hourly basis to achieve a “balanced response”.
Dr Jenny Harries said she expected significant increases in the number of cases in the UK beginning in about 10 to 14 days time, at which point people with flu-like symptoms would be advised to self-isolate.
The vast majority of those diagnosed with coronavirus in Britain were “pretty well” but might “feel a bit rough for a few days”, she added.
Mr Hancock said that “wherever clinically and practically possible” people should access GP appointments “through phones and digital means”, rather than going to surgeries in person.
The number of total cases for the UK include 324 cases in England, 27 in Scotland, 16 in Northern Ireland and 15 in Wales.
There are 91 in London, with the next highest infected area being south-east, with 51 cases. Cases by local council area in England can be viewed here.
The latest person to die, on Monday evening, was a man with underlying health conditions who was being treated at Watford General Hospital.
He caught the virus in the UK and officials are trying to trace who he had been in contact with.
The UK Foreign Office has warned Britons against all but essential travel to Italy, which is experiencing the worst outbreak outside China, after it introduced strict travel restrictions.
Italians are being told to stay home, seek permission for essential travel, and give justification if they want to leave the country.
The Foreign Office is advising anyone arriving in the UK from Italy since Monday evening to self-isolate for 14 days.
The government says it has facilities to accommodate Italian visitors to the UK who need to self-isolate.
British Airways has cancelled all of its flights to and from Italy until 4 April, and has asked staff to take voluntary unpaid leave.
Easyjet, RyanAir and Jet2 are also cancelling their flights on Italian routes, though EasyJet will operate “rescue flights” to bring British travellers home in the coming days.
