Samoa's National Health Services has confirmed three suspected cases of Acute Fever and Rash disease, with blood samples being sent to Tahiti for testing.
One of the suspected patients is a thirteen year old girl who was in American Samoa two weeks ago.
Dr Tile Ah Leong of the National Health Service says the girl has been admitted for treatments.
The test results are expected sometime this week-end to confirm if she has symptoms of Chikungunva currently spreading in American Samoa.
Another case is a 15 year old boy who was recently in New Zealand.
In American Samoa, health officials last week confirmed three cases of the rash disease as chikungunya, a virus similar to dengue fever.
