•Human uterine fibroblasts are susceptible to Zika virus infection.•Both African and Puerto Rican Zika strains can infect human uterine fibroblasts.•A quantitative reverse transcription PCR with primers targeting the envelop regions of the virus was utilized.•Uterine fibroblasts continually produced virus, while maintaining cellular viability over 5 days.•Uterine fibroblasts may be linked with heterosexual transmission of Zika virus in women.
