Since 14 December, at least 16 of the 25 workers at the Princess Elisabeth Polar Station have caught the virus.
Officials say cases remain mild so far.
"The situation isn't dramatic," Joseph Cheek, a project manager for the International Polar Foundation, told the BBC.
"While it has been an inconvenience to have to quarantine certain members of the staff who caught the virus, it hasn't significantly affected our work at the station overall," Cheek said.
