Advice for travellers
Cholera is transmitted through contaminated water or food in areas of poor sanitation. It can cause rapidly dehydrating diarrhoea that can be fatal in up to 50% of cases where medical care is inadequate. However, with prompt intervention with hydration, either by oral rehydration solutions in mild to moderate cases, or by intravenous therapy in severe cases, the case fatality should be less than 1% .
Those travelling to Haiti and the Dominican Republic should practise food and water hygiene precautions. Cholera vaccine is recommended in this situation for those at higher risk, such as humanitarian aid workers and those who will have limited access to safe drinking water or medical care [5, 6].
UK travellers should consult the Foreign and Commonwealth Office (FCO) for advisories relating to travel to Haiti and the Dominican Republic. Country-specific health advice can be found on the NaTHNaC Country Information Page. General advice can also be found in the NaTHNaC health information sheet: Advice for relief workers and other travellers to areas affected by natural disasters.
Those wishing to assist should contact appropriate aid and charity agencies for guidance on how best they can help. Travelling to an affected area independently and without adequate preparation may put a strain on the already challenged emergency and medical services in the area.
Advice for health professionals: returned travellers
Information for health professionals advising travellers returning from affected areas is available from the Health Protection Agency.
