A baby is under surveillance this morning at Hennepin County Medical Center after being taken off a Northwest Airlines flight arriving in the Twin Cities from Asia. Officials were concerned the child might have Severe Acute Respiratory Syndrome. The fatal respiratory disease has killed at least 55 people and sickened more than 14-hundred, mostly in China. The Centers for Disease Control and Prevention contacted Northwest airlines after the eleven-month-old experienced coughing and diarrhea. The state health department says the baby tested positive for a common respiratory infection, but is being observed for further symptoms.
