Abstract

Introduction: Large numbers of confirmed Zika Virus (ZIKV) infections have been reported as a result of vector-borne and non-vector-borne transmission. With a recent ZIKV outbreak, several methods of transmission have been identified during this pandemic. Knowledge of transmission methods is essential to prevent further spread.

Aim: To conduct a literature review on ZIKV and its methods of transmission, to improve the understanding of how the virus may spread.

Materials and Methods: Systematic literature review was performed on methods of ZIKV transmission including: vector-borne, sexual, mother to foetus, blood transfusion, and breast milk.

Results: A total of 18 articles were reviewed involving 2573 cases. Vector-borne transmission was most prevalent in ZIKV cases, followed by mother to foetus vertical transmission and sexual transmission. ZIKV has been detected in blood, urine, semen, saliva, amniotic fluid and breast milk. However, ZIKV is not present in all bodily fluids at one time. Blood and semen have proved to be infectious and a contributory to the spread of ZIKV. It is unknown whether breast milk is infectious to neonates.

Conclusion: Our systematic review demonstrates the influence of different methods of ZIKV transmission possess with the spread of ZIKV. It provides significant implications on testing, prevention and control of ZIKV. Finally, it provides a guide for further research opportunities.
