Melania Trump has decided against accompanying US President Donald Trump to a campaign rally because of a lingering cough after her bout with Covid-19, her chief of staff said.

The event in Erie, Pennsylvania, was to be Mrs Trump’s first public appearance since recovering from coronavirus, as well as her first time out on the campaign trail in more than a year.

The first lady’s announcement served as yet another reminder for the president that, as much as he wishes the virus would “just disappear” – as he has said – it remains a powerful presence in everyday life, including his.

Mr Trump said on Monday that people are tired of hearing about Covid-19

More than 58,000 Americans a day are testing positive for the virus, and more than 700 a day are dying from the disease.

Mrs Trump continues to feel better every day “but with a lingering cough, and out of an abundance of caution, she will not be travelling today”, her chief of staff Stephanie Grisham said.

The first lady last appeared in public for the September 29 debate in Cleveland between Mr Trump and Democrat Joe Biden.

She and the president tested positive two days later.

The first lady announced in a blog post last week that she had recovered from a bout with Covid-19 that included headaches, body aches and fatigue, and had tested negative.

She also revealed that the couple’s 14-year-old son Barron had also contracted the virus, but never had symptoms.

He has since tested negative.

President Trump spent three nights at a military hospital outside Washington receiving treatment for his case of the disease.

He was released on October 5 and returned to active campaigning last week.

Tuesday’s rally in Pennsylvania was to be the first campaign trail appearance for Mrs Trump since she spoke briefly at a June 2019 event in Orlando, Florida, where the president launched his re-election bid.

She addressed a mostly virtual Republican National Convention in August from the White House Rose Garden.

The first lady had planned to headline Trump campaign fundraisers back in March, but those appearances were cancelled due to the coronavirus outbreak.

She is expected to accompany the president to Nashville, Tennessee, on Thursday for his second and final debate against Mr Biden before the November 3 election.
