Tropical Cyclone Gita

Tropical Cyclone Gita passed through Tonga and Fiji on 12-14 February 2018 as a category 4 cyclone, causing substantial damage.

Health Advice following the Cyclone
Over the weeks following the cyclone there may be an increased risk from food, water borne and arboviral diseases. This is due to damage to infrastructure, such as water and power supplies, possible sewage contamination and the proliferation of mosquito breeding sites. The current outbreak of dengue in Tonga could be exacerbated if there is an increase in mosquito populations.

As there is no vaccine to protect against dengue, travellers are advised to use insect repellent, wear protective clothing, and stay in lodgings where there are mosquito screens on windows and doors. The Ministry of Health website contains more advice on avoiding mosquito bites while travelling.

Dengue is a serious viral disease. Symptoms of dengue include sudden fever, headache (especially behind the eyes), joint pain, muscle and joint pain, feeling very tired and rash. If travellers do develop any of these symptoms while away, or when they return home, they should seek medical advice promptly, see further information here. People with severe dengue symptoms require hospitalisation, because the disease is life-threatening. See our related news feature on the Dengue fever outbreak.

Other health advice: 

  • Get vaccinated against typhoid fever and hepatitis A.
  • Only eat thoroughly cooked food and only drink well-sealed bottled or packaged cold drinks if unsure of hygiene standards.
  • Boil drinking water or use water purification tablets if the water quality is doubtful. Avoid ice in drinks.
  • If you have fever, drink plenty of fluids and use paracetamol to manage fever and pain. Do not use aspirin or ibuprofen tablets (and other non-steroidal anti-inflammatory tablets) as they can increase the risk of bleeding from dengue infection).
  • Avoid contact with flood or stagnant water and mud. Wear protective clothing such as gumboots, as well as gloves, goggles, when working in water, soil or mud or with animals. Clean and cover any cuts and abrasions on your skin with a waterproof dressing.
  • Always wash and dry your hands.
