Samoa's Ministry of Health has cleared the first three locals suspected of being infected with the swine flu virus.
The World Health Organization says 1,490 swine flu cases have been verified in 21 countries and Samoan health officials last week started checking incoming passengers for flu symptoms.
The ministry's chief executive officer, Palanitina Toelupe, says three Samoans were put in quarantine, but they have now been cleared as symptom-free.
The ministry and the disaster committee are continuing to screen all people arriving in the country to protect its community from the virus.
Samoa suffered hugely during the flu pandemic in 1918, which killed twenty-two percent of the population.
