🦠 Dengue Fever: What You Need to Know
Dengue fever is a viral illness caused by the dengue virus, spread through the bite of infected (Aedes) mosquitoes. It is most common in tropical and subtropical regions, including parts of Asia, the Pacific Islands, the Caribbean, Central and South America, and Africa.
👉 In Samoa and other Pacific Islands, dengue has caused serious illness and even deaths, so it’s important to know the signs and how to protect yourself; especially if you are travelling.
