House of Travel has confirmed two pregnant women have cancelled trips to Samoa since news of the Zika outbreak was reported.
The travel company has also had inquiries from other travellers about whether they should be concerned about going to other Pacific Islands.
They are being directed to the Ministry of Health website.
The virus is being linked to microcephaly, a condition where babies are born with small heads and damaged brains, and is carried by the same mosquito that transmits dengue and yellow fever.
It has been linked to thousands of babies being born in Brazil with deformities.
In less than a year it has spread to 21 countries, including many in the Pacific.
The vast majority of suspected cases were in French Polynesia (8750), while New Caledonia had the most confirmed cases (1538).
Samoa has reported three cases of the zika virus, with one being exported to New Zealand.
