A huge rise in the numbers of UK residents travelling to malaria endemic areas, combined with a failure to use prevention measures, has significantly increased cases of imported falciparum malaria in the UK over the past 20 years, according to a study published on BMJ.com.
Between 1987 there were 5120 reported cases of the potentially fatal faliciparum malaria, increasing to 6753 in 2002. These findings highlight the urgent need for health messages and services targeted at travellers from migrant groups visiting friends and family abroad, say the authors.
Malaria acquired in one of the 150 countries where it is endemic and then imported into non-endemic countries accounts for a significant proportion of largely preventable disease and death in Europe every year.
Dr. Adrian Smith and colleagues from the Health Protection Agency's Malaria Reference Laboratory, present the latest trends in malaria in the UK between 1987 and 2006, using data from the Malaria Reference Laboratory, involving 39 300 confirmed cases of malaria.
64.5% of 20 488 malaria cases amongst UK travellers had visited friends and relatives in malaria endemic countries. This is reflected by the huge increase in the number of UK residents travelling to malaria endemic areas - from 593,000 visits in 1987 to 2.6 million visits in 2004.
Imported malaria cases were heavily concentrated in communities with frequent travel to see friends and relatives in West Africa.
The researchers also note a worrying trend in cases of the potentially fatal falciparum malaria which have increased steady over the past 20 years in the UK. Of all malaria imported to the UK, 96% of falciparum malaria occurred after travel to Africa. Travellers to Nigeria and Ghana, neither common tourist destinations, account for half of all imported falciparum cases.
