Two UC Santa Barbara students have been diagnosed with the type of bacterial infection which can potentially cause meningitis, and other bloodstream illnesses.
Santa Barbara County Public Health officials say the students are being treated for the illness, and are investigating what led to them becoming sick.
Because it is contagious, UCSB and county health officials are trying to identify people who may have had contact with the infected students, and preemptively treat them with antibiotics.
People can be infected if they are living in close quarters with someone with the illness, or through actions like kissing.
There has been a recent outbreak at Princeton University, but so far, no link has been made to the cases at UCSB.
Symptoms include high fever, headache, rashes, body aches, and vomiting. Treatment is considered essential, because it can quickly become serious, or even fatal.
