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 where each infected person is tagged to one cluster based on
his/her most probably infection location (residential apartment or workplace
address). Each cluster is further matched to fine-grained spatial units termed
as subzones with an average coverage of only about 1.35 km2. Such dengue
cluster dataset helps reveal not only the dengue transmission pattern, but also
the effects of lockdown on dengue spreading dynamics to a certain extent. The
resulting data records are released in simple formats for easy access to facilitate
studies on dengue epidemics.
