[h=3]Abstract[/h] [h=4]OBJECTIVE:[/h] This study aims to examine the synchrony of influenza epidemics between Hong Kong and Shenzhen, two neighboring subtropical cities in South China.
[h=4]METHODS:[/h] Laboratory-confirmed influenza data from January 2006 to December 2016 were obtained from the Shenzhen Center for Disease Control and Prevention and the Department of Health in Hong Kong. The population data were retrieved from the 2011 population censuses. The weekly rate of laboratory-confirmed influenza cases were compared between Shenzhen and Hong Kong.
[h=4]RESULTS:[/h] Unsynchronized influenza epidemics between Hong Kong and Shenzhen were frequently observed during the study period. Influenza A/H1N1 caused a more severe pandemic in Hong Kong in 2009, but the subsequent seasonal epidemics showed similar magnitudes in both cities. Two A/H3N2 dominant epidemic waves were found in Hong Kong in 2015 but were very minor in Shenzhen. More influenza B epidemics occurred in Shenzhen than in Hong Kong.
[h=4]CONCLUSION:[/h] Influenza epidemics appeared unsynchronized between Hong Kong and Shenzhen most of the time. Given the close geographical locations of these two cities, this could be due to the strikingly different age structures of their populations.
