One female patient is in critical care at Daly City's Seton Medical Center, hospital spokeswoman Elizabeth Nikels said this afternoon.
A second patient, whose gender has not been released, remains in serious condition at San Francisco General Hospital, spokeswoman Rachael Kagan said today.
Following the "etd.POP 2010" music festival on May 29, nine partygoers were hospitalized, and two of those patients eventually died as a result of their injuries.
Police suspected the illnesses were caused by overdoses of the drug Ecstasy, Daly City police Lt. Jay Morena said last month.
One day after the event, 23-year-old Santa Clara man Anthony Mata died. A second man - 25-year old San Jose resident Trung Nguyen, who was on life support after slipping into a coma - died a week later.
Nikels said that five patients were originally brought to the medical center in Daly City for treatment after being transferred from San Francisco General Hospital. Since then, four were released or transferred again to other hospitals, she said.
A spokesman from Washington Hospital in Fremont, where some of the patients were transferred, did not return a call for comment as of this afternoon.
