Mosquito-Borne Viruses

Dengue Fever, Chikungunya and Zika Virus

When it comes to mosquito-borne diseases abroad, most travellers might think of malaria as the biggest concern, However, mosquitoes also spread viruses – often in areas than pose no or very low malaria risk. It is important for travellers to understand the risks of these illness, and how to prevent them.

Dengue fever, chikungunya fever and Zika virus are all illnesses that are spread by the Aedes mosquito – which bite predominantly in the daytime. Effects of the illness can range from mild flu-like symptoms, rash, and conjunctivitis, joint pain or swelling, to more serious complications. The geographical distribution of these illnesses has changed and rapidly expanded in recent years. Chikungunya, once a disease found only in East Africa and Southeast Asia, emerged in the Caribbean in 2014 and has now spread throughout the region.

The Zika virus is causing worldwide concern, having already spread throughout Latin America and the Caribbean. The ultimate fear is that it may spread throughout the tropics, to all parts of the world where Aedes mosquitoes are found. Infection during pregnancy carries a high risk of birth defects with obvious implications and concerns for travellers  to affected parts of the world; Zika virus may also remain present in semen for several weeks following exposure – and may then be sexually-transmitted, behaving as a blood-borne virus. Always seek up-to-date advice if you are travelling to a Zika-affected area.

How can I prevent mosquito-borne diseases?

What can I do to protect myself?

Unfortunately, no travel vaccines have yet been developed against these illnesses.

Prevention therefore depends on avoiding mosquito bites, by:

  • Covering up, using long sleeves and long trousers
  • Using insect repellent such as DEET – especially when outdoors, both during the day and at night
  • Using insect nets and clothing impregnated with permethrin
  • Using air conditioning where available
  • Using insect sprays, plug-in mosquito killers or mosquito coils in your bedroom at night
  • Screening windows and doors in the home
  • Reducing the availability of breeding sites for mosquitoes from around the home (mosquitoes need water to breed and often lay their eggs in small vessels filled with water such as flower pots and containers).
  • Steps to control mosquitoes around your accommodation, where possible (e.g. removal/treatment of stagnant water and other possible mosquito breeding sites).
