All three cases are residents in the Hemsley Avenue vicinity.
The Zika cluster is in close proximity to an eight-case dengue cluster reported last month at Bridport Avenue, Cowdray Avenue, Huddington Avenue, Portchester Avenue and Tavistock Ave.
The NEA has commenced vector control operations in the area since the dengue cluster was notified.
Residents and stakeholders are urged to maintain vigilance and continue to eliminate mosquito breeding habitats, said the NEA.
The first Zika cluster in Singapore was reported in August 2016 and about 450 patients were infected with the virus later that year. The last reported case in the country was in July 2017./.
