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.
