Prevent mosquito bites on holiday overseas
In some overseas countries, mosquitoes can transmit serious and potentially fatal diseases such as dengue, malaria, chikungunya, yellow fever and Japanese encephalitis. These are known as mosquito-borne diseases.
Protect yourself against mosquitoes
Anti-malarial drugs, yellow fever, and Japanese encephalitis vaccination are only partially effective and do not protect you against other mosquito-borne diseases. Whilst it is important to seek advice on whether these preventative measures are right for you, the best protection is to avoid being bitten by mosquitoes.
It is important to visit your GP at least six weeks prior to travelling overseas to determine any health risks associated with your destination. In some cases, it may be necessary to get vaccinated or start taking preventative medication before you leave.
Plan. Prepare. Pack.
Before you travel overseas:
- visit your travel GP at least 6 weeks before you leave
- research your holiday destination and know the health risks
- pack long, loose-fitting, light-coloured clothing
- pack a chemical-based insect repellent containing DEET, picaridin or Oil of Lemon Eucalyptus (OLE), also known as PMD
- pack a mosquito net
- consider travel insurance.
Preventing mosquito bites is the first line of defence against mosquito-borne diseases. Many mosquito species are most active outdoors, especially between dusk and dawn. However, some mosquito species that transmit disease will bite indoors and during the day.
Prevent mosquito bites while travelling overseas by:
- avoiding areas of high mosquito activity
- wearing long, loose-fitting, light-coloured clothing
- applying a chemical-based insect repellent containing DEET, picaridin or Oil of Lemon Eucalyptus (OLE), also known as PMD
- sleeping under a bed net, preferably one that has been treated with an insecticide
- closing all doors and windows if they do not have insect screens
requesting hotel rooms be sprayed for mosquitoes if you notice them.
