"I had a fever and a cough before I left - I was so scared," the Chinese traveller wrote on social network WeChat, according to Chinese news platform Sohu.
"I quickly took some medicine and checked my temperature.
"Luckily the temperature was controlled and I had a smooth journey through the border," she said.
She was identified by the Chinese embassy in France as "Ms Yan".
It is not known which airport in France she travelled to or when she arrived.
Her post attracted critical comments. The Chinese embassy in France out a notice on Wednesday (Jan 22) night, asking citizens to comply with border checks.
"Our embassy has received multiple phone calls and e-mails from Chinese nationals regarding a woman from Wuhan who posted on social media about deliberately taking fever medication in order to evade the airport temperature checks," the notice posted on the embassy's website read.
"We attach high importance to this incident and were able to contact Ms Yan, who is involved in this incident. We have requested that she call the French emergency hotline (for her case) to be handled by the relevant departments."
French authorities meanwhile said they would separate any passengers arriving in the country who had a fever so that they could be assessed by emergency health personnel.
Other Chinese embassies, including in the United States, South Korea and Thailand, have issued similar notices to nationals travelling abroad.
In a separate notice on Thursday, the Chinese embassy in Washington said travellers from Wuhan would face extra quarantine measures at five US airports - New York, San Francisco, Los Angeles, Atlanta and Chicago.
In Britain, passengers arriving in London from Wuhan are being placed in isolation to be screened for symptoms.
The death toll in China's viral outbreak has risen to 25, with the number of confirmed cases also leaping to 830, the government said on Friday.
Thailand has reported four cases, Japan and Vietnam two apiece, and South Korea, Taiwan, Singapore and the United States one each.
A second possible case was being tested in the US and the BBC reported five people being tested in Scotland. Patients in these cases were either residents of Wuhan or recent visitors to the city.
