Cuddy had sought out Cameron because Foreman was consulting with a neurologist and House had the rest of the team running around like chickens without heads.
The infant in pediatrics was three weeks old and had a small pustular rash on her stomach. Her heart rate was slow and indeed, her parents lived only a quarter-mile away from the parents of the two dead infants.
Cameron carefully picked up the baby in order to more closely examine the rash. "We need to get the CDC involved," Cuddy said.
"No, we don't." House appeared behind her. "The CDC will set off an unnecessary panic. I won't."
"You're Dr. House?" the baby's mother asked.
House didn't respond. He moved in closer towards Cameron and the baby. "There are no signs of airborne illness here. The CDC will come in with spacesuits anyway and send everyone running."
"Well, sometimes it's better to –" Cuddy's eyes grew wide. "Dr. Cameron, the baby just stopped breathing. Her heart rate's falling."
By the time Cameron moved to hand the baby to a nurse so that they could start CPR (less than a second later), it was already too late. One of the nurses called a code and Cuddy shuttled the parents into the hallway, but they were unable to resuscitate.
Cameron stood frozen, arms open as though there were still a baby in them.
A nurse had to assure Cameron that she hadn't reacted too slowly.
"Did any of you see a dip in the respiratory rate?" House asked.
"N-no," Cameron stammered, and the nurses agreed. "Time of death, 6:12 P.M."
House wrinkled his forehead. "What causes instant respiratory arrest?"
"I don't know." Her voice was still shaking.
"If this isn't in the lungs, it's got to be the brain," House said. "There's no other reason why the respiratory system would just shut off like that."
"Get blood samples and tissue while you can," Cameron told the nurses. "I'll spend tonight in the lab."
