The unprecedented dengue outbreak in Singapore, a dataset of spatiotemporal dengue cases covering the nationwide lockdown period in 2020

Dengue, a mosquito-transmitted viral disease, has posed a public health challenge to Singapore residents over the years. In 2020, Singapore has been experiencing an unprecedented dengue outbreak. As of 7 Sep, the cumulative number of dengue cases for this year stands at more than 28300. We collect a dataset of weekly dengue cases with the locality of each case. Specifically, our dataset captures all dengue cases that are reported from 15 Feb to 9 July in 2020, which covers the nationwide lockdown period from 7 April to 1 June for controlling the pandemics of COVID-19. The locality is matched to spatial units with a high resolution, with an average coverage of only about 1.35 km². The dengue case dataset with such a fine-grained resolution could provide materials for either revealing dengue transmission pattern, or researching on the effects of lockdown on dengue spreading dynamics. The resulting weekly dengue case records with geographical locality are released in simple formats for easy access to facilitate studies on dengue epidemics.

登革热（Dengue）是一种经蚊子传播的病毒性疾病，多年来一直是新加坡民众面临的公共卫生挑战。2020年，新加坡遭遇了前所未有的登革热暴发疫情。截至9月7日，本年度累计登革热病例已超过28300例。
本研究收集了一份包含每例病例所在区位的周度登革热病例数据集。具体而言，本数据集收录了2020年2月15日至7月9日期间报告的所有登革热病例，该时间段覆盖了新加坡为控制新冠（COVID-19）疫情实施全国封锁的2020年4月7日至6月1日期间。
该数据集的区位信息匹配至高分辨率空间单元，平均覆盖面积仅约1.35平方千米。
这种具备精细粒度分辨率的登革热病例数据集，可为揭示登革热传播模式、研究封锁措施对登革热传播动态的影响提供研究素材。
本研究将这份包含地理区位信息的周度登革热病例记录以简洁格式发布，以便于获取，助力登革热流行病学相关研究。
