To explore the epidemiological dynamics of dengue fever.
Epidemiological dynamics of imported and indigenous dengue cases during 2014-2018, including demographic, time-series, spatial and spatio-temporal features, were analyzed.
There were 5 458 imported dengue cases and 59 183 indigenous dengue cases during 2014-2018. Both imported and indigenous dengue cases show seasonal patterns from August to November. 12.9% (12.9/100) of dengue cases were from businessmen. 58.2% (58.2/100) of dengue cases were from individuals between 21-50 years old. Imported dengue cases, mainly from Southeastern Asia, had doubled, and were distributed in 734 counties, 29 provinces, with 50% (50/100) in Yunnan. Except in 2014, indigenous dengue cases were under 5 000 every year, but the number in counties increased dramatically from 51 to 127. The total cases were distributed in 314 districts, 13 provinces. They were clustered in Yunnan border and southern Guangdong. They emerged gradually from southwestern and southern provinces to southeastern coastal provinces, and then to central and northern provinces every year. They spread from the southern regions to the central and northern regions in 2014-2018.
The findings of epidemiological dynamics of dengue fever are helpful to formulate targeted, strategic plans and implement effective public health prevention and control measures.
探讨登革热的流行病学动态。
分析 2014-2018 年期间输入性和本地登革热病例的流行病学动态，包括人口统计学、时间序列、空间和时空特征。
2014-2018 年期间共有 5458 例输入性登革热病例和 59183 例本地登革热病例。输入性和本地登革热病例均呈现 8 月至 11 月的季节性模式。12.9%（12.9/100）的登革热病例来自商人。58.2%（58.2/100）的登革热病例来自 21-50 岁的个体。主要来自东南亚的输入性登革热病例增加了一倍，分布在 734 个县、29 个省，其中 50%（50/100）在云南。除 2014 年外，每年本地登革热病例均少于 5000 例，但病例数在各县急剧增加，从 51 例增加到 127 例。总病例分布在 13 个省的 314 个区。它们聚集在云南边境和南部广东。每年它们从西南和南部省份逐渐向东南沿海省份，然后向中部和北部省份出现。它们从南部地区传播到 2014-2018 年的中部和北部地区。
登革热流行病学动态的研究结果有助于制定有针对性的战略计划，并实施有效的公共卫生预防控制措施。
