CDC Emerging Infectious Diseases media summaries, September 2013
Centers for Disease Control and Prevention (CDC) sent this bulletin at 08/14/2013 03:10 PM EDTGastroenteritis Outbreak Associated with Unpasteurized Tempeh, North Carolina, USA
Salmonella infections are most often associated with contaminated poultry or eggs, but sometimes animal products are not the cause. In North Carolina, an outbreak was caused by contaminated tempeh, an increasingly popular meat substitute made of fermented beans. The contamination had originated in the culture used in the fermentation process.
Continued Evolution of West Nile Virus, Houston, Texas, USA, 2002–2012
Since 1999, when West Nile virus was first detected in the United States, evolution of the virus has been continually tracked by examination of dead birds. Recently, this tracking (surveillance) revealed that genetic changes have been occurring in the virus. During 2010–2012, four new genetic groups of the virus were found in Texas.
Nodding Syndrome
Over the past 10 years, an epidemic of nodding syndrome has affected young children in Uganda and South Sudan. The cause of nodding syndrome is unknown, but it is now recognized as a form of epidemic epilepsy with characteristic rhythmic head nodding. The syndrome occurs in previously healthy children between the ages of 5 and 15 years; the nodding episodes are often triggered by eating or cold temperatures.
