North West Leicestershire MP Andrew Bridgen has confirmed he is self-isolating.
It is understood the Conservative MP made the decision after having lunch with health minister Nadine Dorries in the House of Commons last week, before she became the first MP to be diagnosed with coronavirus.
Mr Bridgen is now awaiting a test.
Speaking from his home, he told Press Association: "I have a cough and a cold but I am working via Skype and the telephone."
Meanwhile, fellow Tory and Charnwood MP Edward Argar - who has self-isolated "as a precaution" - told the BBC he is "feeling fine with no symptoms". He has not yet been tested for the illness.
