“We have established the facts and we will communicate it to the public today on what action will be taken,” spokesman Macks Lesufi said.
“We will send out a press statement later.”
He declined to say anything further.
The department dispatched a team to the hospital on Monday after the Sowetan reported that most of the babies died because they were premature and the hospital allegedly did not have medication for them.
Cockroaches reportedly infested the ward for premature babies, no sanitisers were available for mothers to use before handling babies, there was a shortage of milk formula, and mothers had to buy their own nappies.
The African National Congress met with Health Minister Aaron Motsoaledi over the matter on Monday.
ANC spokesman Zizi Kodwa said an urgent and decisive intervention was needed.
“Should the allegations be confirmed to be true, he [Motsoaledi] has committed to take firm action against all individuals involved.”
