In preparation for the Commonwealth Youth Games in Samoa, people are being asked to prevent the spread of dengue fever.
Samoa's Ministry of Health says it has recorded 475 cases of dengue fever over the past ten weeks.
To prevent the spread of the mosquito-borne disease, the Ministry is asking people to wear suitable clothing during peak mosquito biting times at dusk and dawn.
Communities are also being asked to destroy mosquito breeding sites, like stagnant water in gutters, pot plants and tyres, and to clear rubbish around homes and workplaces.
The Ministry says there has not been a huge increase in the number of dengue cases, and clinics are not overwhelmed.
The Commonwealth Youth Games run from 5-11 September.
