Lymphocytic encephalitis is an actual disease caused by the Lymphocytic Choriomeningitis Virus. Encephalitis is the acute inflammation of the brain. Brain damage and death can occur as a result of the inflammation.
As Doc Cottle stated in the episode, it is usually carried and transmitted by rodents. Unlike the Colonial survivors, humans on Earth are not immune, although infection does not result in symptoms in most healthy adults. It can, however, be deadly for persons with compromised immune systems.
Tahmoh Penikett (Karl "Helo" Agathon) read the "Previously on Battlestar Galactica" line at the beginning of this episode.
As of the beginning of this episode, there are 41,420 survivors, two fewer than at the beginning of the previous episode, "Torn."
This episode contained a warning about violent content and mature subject matter.
Baltar: (to Caprica Six and D'Anna Biers) I was wrong and it was a mistake and I fully admit my responsibility. It will never happen again and I hope you accept my most, uh, yeah, my most humble apology.
Apollo: Sharon...Athena! See what you can pick up on the computers.
