Health facilities, hygiene and disease risk vary worldwide. You should take health advice about your specific needs as early as possible and ensure that vaccinations or preventative measures such as malaria tablets are taken early enough (which may be a month or more prior to departure) to be fully effective by the date of travel.
Sources of information include the Department of Health free leaflet ‘Health advice for travellers’ (available on request Tel. 0800 555 777), the National Travel Health Network www.nathnac.org, your General Practitioner or a specialist vaccination clinic.
