Stelzer, a member of the Kappa Delta sorority, had contact with hundreds of people in San Diego, including her sorority sisters and members of two fraternities - Alpha Epsilon Pi and Delta Sigma Phi - during a party last Thursday before she became symptomatic, public health authorities said.
She attended regular classes until Monday of this week and also spent time at a homecoming celebration last weekend at Moorpark High School in her hometown of Moorpark, California, north of Los Angeles, according to the Ventura County Health Department.
"We are deeply saddened by the loss of one of our students to this terrible illness," Rivera said in a written statement. "Sara was a vibrant young woman who loved San Diego State, her friends and the time she spent at our university."

Symptoms typically begin with headache, neck stiffness, fever and nausea, and the most severe cases can result in hearing loss, brain damage, kidney disease and death.
The bacteria can be spread through direct contact with a sick person's saliva or mucus by way of sharing utensils, kissing or exposure to their throat and nasal secretions.
Although transmission is more likely in close quarters with an infected person, meningococcal meningitis cannot be contracted merely by breathing the air where an ill person has been, public health officials say. The time between exposure and onset of symptoms ranges from two to 10 days.

Students were notified of possible exposure through mass emailings, notices posted on campus and a message recorded on the call-in line of the student health service center.
