Abstract

Healthcare-associated norovirus outbreaks increase later but have a more pronounced seasonality than nonhealthcare norovirus outbreaks. Healthcare-associated norovirus outbreaks had higher correlation with Google Trends activity than nonhealthcare outbreaks (R2=0.68 vs 0.39). Google Trends data may have the potential to supplement existing norovirus surveillance due to its real-time availability.
