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

Dengue,
a mosquito-transmitted viral disease, has posed a public health challenge to
Singaporean residents over the years. In 2020, Singapore has been experiencing an
unprecedented dengue outbreak. We collect a dataset of geographical dengue
clusters reported by the National Environment Agency (NEA) from 15 Feb to 9 July
in 2020, covering the nationwide lockdown period from 7 April to 1 June for controlling
the pandemics of COVID-19. NEA regularly updates the dengue clusters during
which an infected person may be tagged to one cluster based on the most
probably infection location (residential apartment or workplace address), which
is further matched to fine-grained spatial units with an average coverage of only
about 1.35 km2. Such dengue cluster dataset helps not only reveal
the dengue transmission pattern, but also reflect the effects of lockdown on
dengue spreading dynamics. The resulting data records are released in simple
formats for easy access to facilitate studies on dengue epidemics
