[Imported malaria in the hospitals of Marseilles from 1973 to 1976: epidemiological characteristics]
Abstract:
Between 1973 and 1976, 96 confirmed hospital cases of imported malaria occurred in Marseille. The collected epidemiological data indicate the recent increase of the annual incidence and an equal number of cases in immigrants and in people returning from the tropics. Among them, tourists, servicemen and merchant seamen are the groups most at risk. A high proportion of infections are with P. falciparum, mainly from Africa, Malagasy and Comoros. The diagnosis is only confirmed on an average of 6 days after the first medical advice and 2 patients died from falciparum infections. Travellers to tropical countries are often careless about taking prophylactic drugs and the danger of imported malaria should be emphasized.
Insights
Imported malaria cases in Marseille increased between 1973-1976, affecting immigrants and travelers equally. Travelers often neglect malaria prophylaxis, highlighting the risk of imported infections.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Context:
- Marseille experienced a rise in imported malaria cases from 1973 to 1976.
- Epidemiological data revealed an equal incidence among immigrants and those returning from tropical regions.
- Tourists, military personnel, and merchant seamen were identified as high-risk groups.
Purpose:
- To analyze the epidemiological characteristics of imported malaria cases in Marseille.
- To identify high-risk populations and geographical origins of malaria infections.
- To emphasize the importance of malaria prophylaxis for travelers.
Summary:
- Ninety-six confirmed hospital cases of imported malaria were recorded in Marseille between 1973 and 1976.
- Plasmodium falciparum infections, primarily from Africa, Madagascar, and Comoros, were prevalent.
- Diagnostic delays averaged six days, and two deaths resulted from falciparum malaria.
Impact:
- Highlights the persistent risk of imported malaria in non-endemic areas.
- Underscores the need for increased traveler awareness regarding malaria prevention.
- Informs public health strategies for managing imported infectious diseases.
