She was taken by a medical team to the Colonial War Memorial Hospital and was assessed by specialists, he said.
"Her baby was safely delivered by emergency caesarean section two days later. Sadly, her condition worsened and she died five days after admission on 21 July," Fong said.
Fong said 79 cases of the latest Covid patients are from the western division while the rest are from the Central Division.
Seven other people who tested positive to Covid-19 had died. However, Fong said their deaths were not caused by the virus but due to "serious pre-existing medical conditions".
"There have now been 186 deaths due to Covid-19 in Fiji, with 184 of these during the outbreak that started in April this year.
"The ministry also has recorded 94 positive patients died from the serious medical conditions that they had before they contracted Covid-19 and these were not classified as caused by the virus."
Meanwhile, Fong said some people are more focused on undermining the ministry's efforts to combat Covid-19.
His comments come amid a video that surfaced on social media recently, which showed how dead bodies were being kept at the country's main hospital, the Colonial War Memorial Hospital's temporary morgue.
The video showed a container located outside the mortuary full of dead bodies.
"Fortunately, together with our private sector partners, we have expanded our morgue space to address this issue," Fong said.
"This supportive effort by Suva Morgue Services highlights the positive spirit that is well appreciated by the Ministry of Health and Medical Services."
He said there was a group tasked by the ministry to facilitate funerals of Covid patients.
Fong said the seven-day average of new cases per day is 1046 or 1182 cases per million population per day.
He said with the high numbers of new daily cases, the ministry was also seeing increasing cases of severe disease and deaths.
Fiji now has over 17,000 active cases in isolation.
