Dengue cases are increased In Samoa, American Samoa and French Polynesia currently. So, remember to take repellent and use it to prevent day time mosquito bites when visiting these countries. According to Samoa's Ministry of Health, more than 1,500 suspected and confirmed cases of dengue fever (serotype 2), a significant increase over average incidence, occurred from August to November and high numbers are still being seen. Cases are particularly on Savai'i and Upolu islands, mainly in Apia and the districts of Gaga'emauga and Tuamasaga (Upolu Island). The last dengue outbreak (serotype 3) occurred in 2015-16. In French Polynesia it is dengue 1 circulating currently.
The Pacific has the climate and environment for mosquitos to thrive and movement of people ensures the different strains of dengue virus are introduced regularly to different countries in the region. Dengue, chickungunya and zika are all transmitted by the same day feeding mosquitos which are common in the Pacific so always remember to try and prevent mosquito bites when there.
