  • Malaria: Raja Ampat area
    There is malaria in the region for the Raja Ampat cruise – this area is around the equator and we recommend you discuss this with your doctor. Certainly when we walk in the jungle early mornings you will need to cover up well and also use mosquito repellant. We have a supply on board but suggest you bring your preferred brands. And from the Raja Ampat Tourism Association: Papua is a malaria area and you are advised to take precautions and follow the advice from your local health centre. Note that the medication Lariam has limited effectiveness in this area due to a resistant strain of Malaria and is not recommended. Alternatives could be Malarone or doxicycline.
  • Malaria – Komodo area
    Generally speaking basic precautions such as covering at dawn/dusk and using mosquito repellant for land tours is satisfactory. If you are in doubt whatsoever, please liaise with your doctor.
