Former DUP North Belfast MP Nigel Dodds is now working on internal party matters, his wife has said.
The senior party figure lost the seat to Sinn Fein's John Finucane last year after 18 years.
He had also served as the party's leader in the House of Commons and played a high-profile role in advocating for Brexit.
However, he and his party consistently voted against the Prime Minister's Brexit withdrawal agreement, and against the Brexit deal negotiated by Boris Johnson's predecessor Theresa May.
Speaking to the Belfast Telegraph, the Economy Minister and Upper Bann MLA Diane Dodds said her husband had been keeping well since the end of his Westminster career.
"He's grand. He's working on some internal party stuff at the minute. He's fine, totally fine," Mrs Dodds said.
In the context of the suffering of many people directly affected by Covid-19, she added: "We're very fortunate, we're well, that's all that matters."
She said coronavirus had also affected the grieving process of families who had lost loved ones to causes other than the virus due to restrictions on the numbers who can attend funerals.
"Having 10 people at the funeral, no grieving ... it's terrible," she said.
Mrs Dodds became Economy Minister in January after 11 years as an MEP. She has faced a challenging time in office as her department has reacted to the impact of coronavirus and lockdown on the economy.
"I thought this would be the simpler life," she joked when asked how her present role compared with being an MEP.
Mrs Dodds said the department would be distributing over £400m in support to stricken businesses through grant schemes of £10,000, £25,000 and a separate micro-businesses hardship fund, which opened to applications last Wednesday.
She said it had been a very busy time dealing with the concerns of businesses, and this week had been communicating with up to 180 businesspeople at a time through video conferencing. She said the Executive had put health at the heart of its strategy for dealing with coronavirus and economic recovery.
