Improved surveillance systems are needed to identify rare but difficult-to-diagnose encephalitis cases resulting from pathogens transmitted during organ transplants, according to a recent report.
From 2002 to 2013, the Centers for Disease Control and Prevention investigated several US encephalitis clusters among transplanted organ recipients. The investigators found that some cases were caused by emerging pathogens including West Nile virus, rabies virus, lymphocytic choriomeningitis virus, and Balamuthia mandrillaris amebae (Basavaraju SV et al. Emerg Infect Dis. 2014;20:1443-1451).
