With four diagnosed cases of meningitis at the University of California, Santa Barbara, decision makers have canceled several fraternity and sorority events. The fourth case was announced on Monday, The Washington Post reported.

The symptoms of meningitis are swift and serious, brain and spinal swelling among the most life threatening, but they are usually overcome through timely treatment. Of the eight documented cases at Princeton (the first occurring in March), five are recovering or have made full recoveries, one was being treated out of state so his progress hasn't been updated, and the two most recent cases from November are also pending an update.

The outbreak at UC Santa Barbara, which began in November, has already been more damaging. A freshman had his feet amputated when the infection cut off circulation to his limbs, according to The Post.

Because the disease is spread through close contact, UC Santa Barbara has issued probiotics to any student who may have come into contact with the four diagnosed cases. To better protect the entire population, the school has thoroughly cleaned all public facilities, such as cafeterias, athletic facilities, and residence halls, according to The Post.

Princeton has taken a more proactive approach. The B strain that's affecting its campus corresponds to a vaccine that isn't yet available in the United States, however, the CDC has granted the college permission to export the drug from overseas and dispense it to students. The vaccine will be available on Dec. 9, according to NBC News.
