Narcolepsy onset is seasonal and increased following the 2009 H1N1 pandemic in China
Annals of Neurology , 08/23/2011
Han F et al. – In China, narcolepsy onset is highly correlated with seasonal and annual patterns of upper airway infections, including H1N1 influenza. In 2010, the peak seasonal onset of narcolepsy was phase delayed by 6 months relative to winter H1N1 infections, and the correlation was independent of H1N1 vaccination in the majority of the sample.
