Parly told French lawmakers on Monday that one sailor from the Charles de Gaulle remains hospitalized. Others have recovered.
The number of positive cases reached a total 1,046 out of 1,760 sailors onboard the aircraft carrier.
The investigation shows that the virus first infected people after February 26, while the carrier was at sea, Parly said.
The virus was then introduced again onboard during a stop in the French port of Brest in mid-March, as the country was about to enter into lockdown.
Parly said the commandment established precautionary measures, like increasing physical distance between sailors, but they were lifted at the end of March because of concerns of the low morale of the troops.
She said the virus was not detected onboard before April 5. (AP) SCYSCY
