In Samoa, thirteen students from Vaipouli College on Savaii Island tested positive for the H1N1 virus or swine flu last week.
The results mean the number of confirmed swine flu cases in Samoa is now 29.
The Ministry of Health is strongly advising all schools and parents in the country to ensure that any student found to suffer symptoms of the flu should be kept at home until they are fully recovered.
Meanwhile, the affected college students were treated with Tamiflu last week and some returned to school yesterday.
