Macron tested positive for the virus on Thursday showing symptoms of fatigue, coughing and muscle aches.
The president, who self-confined in an official residence near Paris from where he is running meetings remotely, had promised daily updates on his health.
He is now “showing signs of improvement,” the Elysee palace said, without giving details.
All previous daily updates had said that the 43-year old president was in a “stable” condition.
Here's Covid-patient Emmanuel Macron – in slightly less grand surroundings than his usual broadcasts – reassuring us that he's fine and begging everyone to continue observing covid protocols despite the “moment of negligence” that lead to him catching the virus https://t.co/XjgNsPhZn2

The Prime Minister Jean Castex, who has been self-isolating since Macron's diagnosis, tested negative for the virus on Wednesday, his office said, so can now resume his duties in person.
The French authorities are concerned that the holiday period could see a new spike in infections, after the country's total Covid death toll went above 60,000 last week.
Authorities said on Tuesday that nearly 12,000 new cases had been reported in the previous 24 hours, and 386 deaths.
A vaccination campaign is to start on Sunday, with health workers and older people among the first to get Covid shots, the government said.
The EU gave the green light for the Pfizer-BioNTech coronavirus vaccine on Monday, paving the way for the first inoculations to start across 27 countries soon after Christmas.
