Advice for All Destinations

The risks to health whilst travelling will vary between individuals and many issues need to be taken into account, e.g. activities abroad, length of stay and general health of the traveller. It is recommended that you consult with your General Practitioner or Practice Nurse 6-8 weeks in advance of travel. They will assess your particular health risks before recommending vaccines and /or antimalarial tablets. This is also a good opportunity to discuss important travel health issues including safe food and water, accidents, sun exposure and insect bites. Many of the problems experienced by travellers cannot be prevented by vaccinations and other preventive measures need to be taken.

Measles occurs worldwide and is common in developing countries. The pre-travel consultation is a good opportunity to check that you are immune, either by previous immunisation or natural measles infection.

Ensure you are fully insured for medical emergencies including repatriation. UK travellers visiting other European Union countries should also carry the European Health Insurance Card (EHIC) as it entitles travellers to reduced cost, sometimes free, medical treatment in most European countries. Online applications normally arrive within seven days. Applications may also be made by telephone on 0300 330 1350 or by post using the form which can be downloaded from the website.

For Travel Safety Advice you should visit the UK Foreign and Commonwealth Office website.

A worldwide list of clinics, run by members of the International Society of Travel Medicine is available on the ISTM website.

Boosters are usually recommended in a country or situation where the correct treatment of an injury may not be readily available.
