Case report: Zika surveillance complemented with wastewater and mosquito testing.

ABSTRACT:

Background

In June 2023, a local cluster of 15 Zika cases was reported in a neighbourhood in Northeastern Singapore. The last significant local transmission of Zika virus (ZIKV) with more than 450 cases was in 2016-2017.
